I’ve been experiencing some strange issue with my domain user in Exchange – I would be glad if anyone can assist me in this strange issue. I’m domain admin and my account was working fine – but in recently while I was working I got an prompt in Outlook to input my username & password – despite of giving the correct inputs the pop-up continues – when I tried to access through OWA I’m getting the above attached error message. After tried various troubleshooting approach I couldn’t figure out the issue – even I tried to move my mailbox to different mail storage but no luck. Then I deleted my domain account completely and clear the mail storage – it was working fine for few weeks but again same issue reappears. I have delegated full access to one of the account and through OWA I’m able to access my emails but not through Outlook. Would you kindly assist me in this strange issue? Since I'm affraid if this issue happens to other users Would you kindly also let me know how can I make pst file for my emails from Exchange Powershell ?

Are you using RPC over https for outlook connection? Is it only your account or even others are facing the same issue? Did you try to disconnect and reconnect your mailbox from the user account?Raj

You shouldn't be using an account with elevated permissions for everyday work. Give yourself another account to use, then disable your mailbox in EMC. The reconnect the mailbox to the "normal" user. Log in as the "normal" user and use "runas" when you need to be a domain admin. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Maybe there are some permission issues You can remove explicit Deny for Exchange Servers Rights from Exchange Server object: Store Constrained Delegation Store Read and Write Access Store Read only Access Store Transport Access And you could refer to http://support.microsoft.com/kb/2172960 Cheers Zi Feng
