Blackberry 10 device ask for AD account password from time to time



We have a Blackberry 10 server setup adn we have about 15 users on it  currently (rest are on the old BES 5 paltform) on a mixture of Z10 and Q10 devices. We are using Exchange 2010 as our mail server. 


Al is working fine except a random group of BB10 users would get an error on theis handheld devices saying

"Account not responding" or "Account is not sync". When this error pop up users are not able to send or recive emails.


Resolution is to go to Settings -> Accounts -> and then enter the users AD account password.


This does not happen to every BB10 user at the same time, but when thsi happens it'll effect a number of of users. Its not always the same group of users either and there's no set time interval between the errors.


When this error pop's up users passwords ahve not expiered or accounts locked out. Some of these users have iPads and have their corperate emails set (via active sync) on the device and email works fine in that deviec platform. Which leads me to think the issue is with the new BES 10.


At the time this error pops up i get thsi error in the event viewer in the BES10 server

Re: Blackberry 10 device ask for AD account password from time to time

This is BB's recommendation  http://www.blackberry.com/btsc/KB33558


We decided to go with this, and it resolved the issue for us:



The issue is caused with a timeout based authentication that affects the active sync.

  • Open the web listener of your ActiveSync rule, go to properties > Forms tab > Advanced, and uncheck “apply session timeout to non-browser clients”.

Re: Blackberry 10 device ask for AD account password from time to time

Thanks Marissa for your input. We do not use TMG instead we use FOPE so there no seperate rules for Actiev Sync.
