TyTN "forgets" personal certificate

[ascalon]

I try to get my mails pushed to my TyTN. Thus I enabled the appropriate services on my Exchange 2003 SP2 server, set the user permissioning and so on. I generated an P12 cert with my CA and imported it using p12import.exe on my tytn. I also installed .cer for the domain and for the CA on the mobile device. Thus I was able to sync and push. Now I am facing the following issue:

After successfully syncronizing and pushing for some hours, I regularely get an 0x85030027. Checking my certificate I can see that my p12 is gone. After reimporting it using p12import, i can change the server settings the following way to force an "reinitialisation" of the link between user settings and cert: I delete the "m" in "blabla.dynaccess.com", go forward to login information - the password is gone then - go back to the server, add the "m", go forward adding the password. Sometimes I am than able to sync again, sometimes I get an 0x85010004. In the latter case I must delete the whole server setting - loosing all my mails - and have set it once again.

Dealing with this issue now for several days and beeing unable to find any description or solution in this forum and the web, I kindly ask for any idea which could be considered beeing helpful...

I use CACert certificate for my email and have imported it using smartphoneaddcert (http://download.microsoft.com/download/0/3/b/03b3162a-c093-4434-917c-4b289d027ceb/smartphoneaddcert.exe) utiltity from Micro$oft.

Copy your certificate into \Storage\root.cer (has to be named like this) and run SPAddCert.exe, hopefully that should work :)

thanks for the immediate answer. i already installed my root-certificate with no probs. The issue I have is related to the individual cert for the device, generated and signed by my ca, which is trusted by the tytn. This individual one disappears after some syncs?!

I think your method is ok (Jacco in DDSL.NL) have a nice tools to import personal certificate to device...

Now I can describe the problem more precise: the personal certificate disappears after every soft reset?!

I have the exact same problem !!!!
When you do a soft reset the personal Certificate disappears.
I can reimport it directly, but I need to hook it up to a PC in order to validate the Certificate.

Is there no other way. This is really annoying when i'm on a trip, and I have to soft reset the device.

Does anyone know hpw this can be done differently.

Thanks
