We recently migrated all of our users over to Exchange 2010. After the switch, some of our iPhone users are receiving a prompt each morning to enter their Exchange password. If the user clicks "OK" or "Cancel" the message goes away and their mail works fine the rest of the day. That is, until the next morning when the prompt appears again. I don't know the exact time that this happens, but each user just says when they wake and unlock their phone, the prompt is on the screen. I've been working with MS Exchange support for a month now with no luck. It's such a hard thing to troubleshoot when it only happens once a day and I cannot force the error to happen until the next morning.

This is not happening to all of our iPhone users, just some. My iPhone has been fine from day one. MS Support can't seem to find anything different about my account (or any of the working accounts) compared to the accounts that are getting the prompts.

Has anyone seen this before? Or know how to fix? I've found a couple "fixes" online in some forums but none of them have worked for us.
iPhone 4 + 3GS, iOS 4

    I have the exact same issue on my iPhone and iPad. Our company just migrated to exchange 2007 in November. Each morning I get the promptmon both devices after unlock. I thought this was due to our company lock out from 12am - 6am for backups, but hearing you have the issue has me thinking it's a software bug.

    I also am having isssues with the phone downloading messages. It just keeps saying "connecting" but takes in some cases 30-60 minutes. This is even with 5 cell bars and full n band wifi. I also am running MobileMe and gmail on the phone, but only MobileMe and exchange are set form push.

    Please help if you can. Thank you.

    Have you looked to see if these users login time restriction is set to a specific time window? Data sync also works with this restriction.

    Hello wjosten,


    We are experiencing the same issue with users getting prompted, but Apple device users only.  Where do I go to check on the user's login time restriction?  Is this an Exchange setting or AD?  I checked the setting in AD for these users and they can logon 24x7.  Not sure where else to look.  Thanks.
