I have a Comodo Personal email certificate, which I use for signing and encrypting emails using the S/MIME protocol, over MS Exchange.
The Samsung stock Email application supposedly allows the use of such certificates natively. However I am running into problems when I attempt to install my key.
I'm using a PFX file exported from Windows Certificate Manager. When I generate the file using the standard wizard, I have the option of exporting my key and user certificate either with or without the other certificates in the chain of trust.
The complete certificate chain, by the way, is as follows: Private key/Personal Cert --> Intermediate CA (Comodo RSA Client Authentication and Secure Email CA) --> Root CA (COMODO RSA Certification Authority, included in default store)
When I omit the other certificates in the signing chain when exporting, the PFX just installs my key and my user cert in credential storage. But then everytime I use it to sign or encrypt something in the Email app, I get a nag from the Email app warning me that it could not validate my credentials. That is, Samsung Email app is unable to verify my cert's trust unless the intermediate CA is provided to it.
But frustratingly, when I export the PFX file so that it includes the intermediate CA's in the chain and install, Android places the Intermediate CA in User folder in the keystore, and treats it as a root CA. That is to say, instead of inheriting trust from the COMODO RSA Certification Authority (which is in the default keystore) Android assigns trust to the intermediate CA *explicitly*. And so, despite the fact it's a valid certificate signed by a trusted root authority in the default keystore, Android gives me nearly constant nags about my phone being "monitored by a 3rd party" until I delete the intermediate CA from User Trust. Which of course, breaks the Samsung Email app's ability to verify the certificate chain and yields a nag everytime I send an email.
Anyone else encounter this issue/know of a solution?
Bump.
I've scoured the internet for months and I cannot find a single thread anywhere on exactly this issue. It's a pretty straightforward question, I think. So I'm surprised I can't find any insights anywhere.

hello ppl,
does anyone know hot to make WM6 trust a certain root CA/certificate? I have a Commodo SSL certificate on my exchange server and because WM6 doesn't trust it (for some reason), I cannot use Push Mail.
installing the certificate doesn't help.
Does the Root Certificate appear in Settings/Certificates/Root?
Has the Root Certificate been installed on the device OK? i.e. does it appear in Settings/Certificates/Root? If it does that should be enough for your device to trust it and certificates issued by the same CA.
I have two root certificates installed on my WM6 device (over the default ones) -one for push email and the other for Wireless (I also have a client certificate for wireless since we use EAP-TLS for Wireless Authentication). The one for push email was installed via a .cab file, the other automatically installed when I enrolled for the client certificate from an AD-integrated CA via ActiveSync.
Some info here for creating a .cab file for your root certificate:

when I install the certificate it appears as an intermediate CA.
am I installing the wrong certificate?
Ok I have wrestled with this for 2 days straight.
I had issues with this with my CFO's windows mobile device but at least his was giving me a specific error message.
My Tilt has the latest Dutty ROM upgrade (Dual Touch), I haven't been able to get my exchange server synced OTA.
I run a Exchange 2007 Enterprise environment. Everything on the server side is fine. My OWA url is https://webmail.firethornmobile.net. All I get is waiting on network after 2-15 minutes.
I have soft reset, deleted the PC partnership, taken my connection off of auto and tried both my work connection and isp.
I'm starting to suspect it maybe the ROM upgrade but it was doing the same thing when I first started the phone.
Please help.
OMA enabled?
Do you have the OMA enabled? Do you have the server root CA installed in the tilt (I am assuming you are using secure method for OMA)?
I have flashed Dutty's dual touch v2 and I don't have problem to get emails through OMA services.
Do you ever get the other PDA sync with email before? From the error message, it seems the Activesync in the Tilt can't talk to the exchange (front end) server at all.
Yes on Exchange 2007 OMA is enabled natively. In the middle of seperating data centres from our sister company.
We just got bought by Qualcomm so we never bought a cert from Verisign. I am using a self sign cert from our exchange server ( I have to turn SSL off on the pda side.
This has never worked, I already called Cingular and they said if I can get webmail from gmail and hotmail then it isn't their problem.
I have installed the self signed cert on the handset.
OK, you don't need to install the self-signing cert in the PDA, but you need to install the root cert of the self-signing cert in the PDA.
Usually, a server cert or user cert has a root authority (CA), you need to install the CA cert in the PDA, not the server cert.
If you can install a window server (2000 or 2003), you can enable the certificate authority server and issue your exchange server a server certificate. In this case, you will have your own root certificate. I don't suggest you to use Verisign's certificate because everyone has Verisign's root certificate can try to "play" with your OMA server.
However, the error message is still showing that the Activesync in PDA can't reach to the OMA at all.
BTW, the push email doens't work if it's not on the SSL connection.
I apologize that I wasn't clear. Its is the root cert from the CA (Which is our DNS server).
I realize the message means that it isn't getting to OMA. I have been on the phone with AT&T and HTC aboutthis and no one can tell me why it can't connect. I have been given tons of different network settings by AT&T and HTC and nothing changes. I get different error messages but when i put everything back to the way it should be it still gives me this generic message.
I have configured my CFO's handset to get email (Its Palm Treo with WM 6.0) and even though that was a pain in ass it still works (just as good as his Blackberry) and he has SSL unchecked as well.
In that case, you can try to see if you can reach to the OWA from your PDA, if it can, you shall not have network issue.
BTW: the connon name of the server cert must be the same as your public domain name, otherwise, the Activesync will still reject the connection.

I agree with the poster above. I have this exact same set up at my company and it does work. The certificate has to be the external name of the exchange server. If this does not match the PDA will never sync. Check your certificate and make sure the FQDN is correct.
I just check your exchange server from the URL you posted above, your OMA and OWA are working, but the certificate's common name is not the same as the public domain name.
Try to re-issue the certificate, it may just work.
Thanks guys. I'll try that.
Webmail does work from the handset. I don't know how I got my CFo's working to be honest if its flaking on the name of the cert but I'll try that and let you know. I was about to hard reset this thing and leave the cooked ROM's alone for a while. Hopefully this resolves it.
From my experience dealing with Acticesync in the PDA, it's very picky of the name of the certificate. I think that's security reason. The Activesync doens't accept certificate that common name doesn't match the public domain name.
When I use the IP address for test, I have to get a certifiate with the IP address as its common. So I believe that's the certificate's problem, not the cooked rom.
I still suggest you to get your own CA and certificate, in that way, you have more control even debugging this problem.
I feel like a moron asking but how the hell do I change the common name.
You can't change an existing certificate, you have to re-issue a new certificate.
I guest you can't do it by the self-siging certificate, but I am not fimiliar with the self-signing certificate. Get a WIN server machine and install the CA server, after that, you can issue a certificate.
Assumeing you have a CA server ready:
1. Request the certificate from exchange server: you will have a chance to enter the common name of this certificate.
2. Generate a certificate from this certificate request from CA server
3. Import the certificate back to the exchange server.
If you can't get a WIN server as CA server, I will need to ask my colleagues about the free CA server he used from the Internet.
My DNS box is a CA server (started the service on that).
I'll try that then (I hard reset and I now I have an error stating I'm not authorized).
I'll let you know if it works. Thanks.
Ok I believe I did it right but I still get tha error (When connect via usb cable) and I still get the waiting for network message.
When you connect to the USB cable, you have to "allow" the Internet access pass through from the Activesync in the PC, otherwise, it won't reach out to the Internet at all.
Try to connect to other web site to see if you have a good internet connection or not.
Some updates. I made sure the cert is the right common name. I noticed that after I install it on the handset it doesn't put the cert in the root tab...only intermediate. I installed the ca server's cert as well (That went into the root tab).
Im leaving ssl checked and now I get 0X80072F17.
incorrect common name
Your common name is still not correct, it shall be "webmail.firethornmobile.net" only, but you put "http://" at the begining and "/owa" at the end, it not correct.
You have to issue the server certificate one more time with "webmail.firethornmobile.net" (without quotes) as the common name.
Also, when I check the Certification path of your certificate, I don't see this certificate is under any root certificate. Properly you need to check your CA (DNS) to see if it's setup properly.
Hey,
Use this site to figure out the errors you are getting on your phone. http://www.pocketpcfaq.com/faqs/activesync/exchange_errors.php
Also are you the Exchange Admin? If so enable verbose logging so that you can see what is going on with exchange as the connection comes in.
Also if you want to make sure it is not the cert you can "Enable" SSL on the phone and then reg hack it so that it doesn't check for the cert. this will allow you to see if it is a cert problem.
Let me know if you need any help with that. I"m an Exchange Admin and i work with Active Sync day in and day out.

I continue to get the same error even after dumping the device through the exchange server.
My System Admin thinks that there is something wrong with the version of ACTIVE SYNC provided in the ROM used to flash the device.

I am attempting to access my company Exchange server.
My company has a encrypted network. Can only access from external network by using a VPN link provided by a "Check Point" software (on a PC). The encryption provider is "Verisign".
I built a "L2TP/IPsec CRT" VPN link on my cell phone (Android 2.1) and successfully imported a personal certificate from a .P12 file issued by company IT. But I don't have a CA certificate to import. I found many certificates in my PC(win XP), Named as " verisign Class #*** " or " Companyname root CA ***". I tried some of them(export .CER file, and converse it to a .P12 file, import to Android) but failed to get acess to the server. Can somebody help me on this, please?
It's best to request CA root certificate from your IT people. If they don't have it, perhaps one of these will be a match:

Hello,
We have roughly 15 Motorola Xooms as well as numerous Android Personal Devices on our network. We have a certificate for our Websense Web Filter that allows it to filter and inspect SSL traffic. When we install the certificate onto our PCs and iOS Devices they are able to view all traffic just fine. When we install the certificate onto our Android Devices, we get certificate errors. We have tried changing the formats of the certificates and haven't gotten anywhere. It looks as if it is putting it into the incorrect certificate store and not the Trust Root Certificate store but I can't find anyway to manage the certificate stores on the Android Devices. Any ideas?
I have a personal Honor 8 device I use to access my company email. They use Duo Mobile software to authenticate before allowing this.
After upgrading to Nougat 7.0, I am unable to access email (using the Outlook app). I get a message saying that I need full disk encryption turned on. I don't see this as an option anywhere in my Settings. I do have a strong password set to be used.
Do I need to enable File Based encryption at this stage? I am trying to do this and do not see the option to convert to File Based encryption even after turning on Developer Options by the way.
Has anybody else run into this issue? Any guidance - I am dead in the water without being able to access my email.
Thx
AK
I remember I had a problem with my e-mail but I'm not 100% certain that it was the same issue. But try to remove all your screen locks including finger print and try again.

Thanks for the response. However in order to enable Corporate Email, Outlook asks for a password to be in place. Therefore I cannot remove all screen locks.
The problem seems to be that the authenticating software (Duo Mobile) is looking for two things on the device. One is that full disk encryption is explicitly enabled. The other is that the setting to "Require password at Startup" is enabled. Neither of these options are availalble on the Honor 8. Their support says that encryption is on by default and therefore there is no setting for it.

Further, I looked at turning on the new File Based Encryption that is part of Nougat. There are how-to's that discuss this, where you have to turn on Developer Options to do so. However, on the Honor 8, even after turnin on Developer Options, there is no option to "Convert to File Based encryption" available. If you search in Settings, it shows this option, but upon clicking on that option from the Settings Search results, it just takes you into Developer Options and there is no setting to enable File Based encryption.
Nvm this, poor reading comprehension on my part
I have no issues using Gmail's Exchange client to connect to my corporate email. It sounds like it's not a Nougat or Android problem, it's a Duo Mobile problem
I had the same problem.
Switched to the app Nine. It is a one-time purchase and its security model is app-wide instead of device-wide.
Have you tried it yet?

The company whose email I need to get to has only enabled Outlook as a client - therefore using other email clients (such as the Gmail app) is not an option unfortunately.

To the best of my knowledge as long as you have the correct server credentials, you can use any client. For example, my credentials:
Server: subdomain.website.com
Domain\Username: test\Telperion
Port: 443
Security type: SSL/TLS
I can connect using Gmail's Exchange client, Outlook for Android, Nine, native Huawei email client, etc. While everyone's setup is different, if you're able to log in using the Outlook client, theoretically there's nothing to prevent you from using the same credentials in a different client.
That was my not my experience.
My company's Outlook server is configured to require device-level encryption for mobile devices with complex passwords. On my Nexus 6p, Outlook for Android did not work, with the error that it "did not support the encryption required". Also, I could not use fingerprint authentication on the device, and required a 8-digit unlock code. Not just for Outlook, mind you -- any time I wanted to unlock the phone.
OWA (Outlook Web App) for Android worked fine, but it supports neither push nor notifications, rendering it utterly useless. OWA is, as far as I can tell, just a shell containing an HTML rendering engine that reflows the web app.
The only reason CloudMagic (and potentially Nine) worked for me is that CloudMagic (and I think Nine) have device-level encryption on their server (?). The end-user provides credentials for their server to log in, download the email, and act as an intermediary.

When adding my corporate exchange email to Gmail, Gmail is activated as a device administrator with permissions to:
Erase all data
Set password rules
Monitor screen-unlock attempts
Lock the screen
Set lock-screen password expiration
Set storage encryption
Disable cameras
I'm not using webmail, I'm using Exchange ActiveSync. Device policy forces me to have a lock screen pin or password, but I can still fingerprint unlock it. It sounds as if your respective Exchange servers aren't configured properly, because all of the security that they're requiring can be mandated through ActiveSync and Gmail's device administration service.

Is Exchange ActiveSync different from Office 365's Exchange?
When I asked IT about local ActiveSync, they said that they don't support it, just Office 365 on Shibboleth.
Then again, I couldn't get a Chromebook to connect to the WiFi network here due to some misconfiguration in their Cisco router's PEAP setup, so I wouldn't be surprised.

Different back end, same capabilities. Exchange ActiveSync is a site-hosted server, Office 365 is a cloud-hosted version. On a local Exchange server, your IT department will have set up a local domain and you will have a user account in Active Directory (domain\Telperion). In Office 365, your user account is your email address ([email protected]) and there is no domain mapped that you have to configure. Once you know this, you can piece together the way to configure it.
The biggest challenge is that IT typically won't mess around with supporting mobile device configuration ("I don't know Android"), and Microsoft tutorials don't give clear instructions ("I don't know Android"). Android tutorials say "I don't know Microsoft" so you end up having to piece things together from multiple sources online.
See attached tutorial, it's very easy once you know what to do.
Add new account from device Accounts menu
Choose 'Exchange' with the Gmail logo
Enter your corporate email address, don't hit next, hit "Manual Setup"
Choose 'Exchange' as the account type
Make sure your email is entered in "domain\username" field
Enter password
Server for Office 365 is "outlook.office365.com"
Port 443
Set security to "SSL/TLS"
From there it should handle all the rest of the configuration.

Thanks. Tried Nine. Works the same way as Outlook so far. In other words, setting its policy to only apply to the app doesn't make a difference in how Duo Mobile (the two factor authentication checker) continues to insist the device be encrypted and have the setting "Require password on startup" be turned on.

Thanks for the detailed message. Tried the above.
When I left the server be the default server name (derived from my email address), I got a "Certificate is not valid" error. I had "None" as the certificate.
After I changed the server name to be outlook.office365.com as mentioned in your instructions above, I now get a "Can't connect to server" message.
I did recheck my steps. Not sure why Gmail fails to connect. Any suggestions on where to look?
