Windows – Outlook 2010 needs a password every 30 minutes

exchangeoutlook-2010windowswindows 7

I have an Exchange Server running Exchange 2010. I have one specific user who we just migrated over to Windows 7 x64 an he is also running Microsoft Outlook 2010 x86. Our exchange mailboxes are tied directly to their Active Directory accounts, so they do not need a password to open Outlook.

Now the problem that only one of my users is running in to. Every 30 minutes or so he gets a notification down in the status bar at the bottom of Outlook that Outlook needs his password. He clicks on the notification button and his mailbox updates. I have no idea what is causing this.

I have tried renaming the profile under:
%userprofile%\AppData\Roaming\Microsoft\Protect but this did not resolve my issue.

I have searched high and low for a solution and nothing seems to be relevant.

Thanks for your help in advance.

I had the same problem not so long ago. Took me 6 months to fix this :)

By GPO you need do disable "Outlook Anywhere". Outlook jumps between TCP and HTTPS/RPC for no reason, and HTTPS/RPC asks for a password.

Disabling "outlook anywhere" in outlook directly will fix the issue until the next reboot, then outlook will reset it to the default as requested by the Exchange Server.
