Exchange 2010 - unable to connect to an account that was disabled / enabled

In the process of troubleshooting a problem with a user's mailbox, we had to disable the mailbox in Exchange console, and then re-enabled the account. Since then, Outlook or OWA can not connect anymore to the mailbox. OWA says that the account is disabled. The mailbox does not show as disabled in Exchange Management Console

We had done this exact same procedure a few minutes before with another user and the reconnection worked fine. All the other users on this Exchange server that we have not modified work fine.

Any idea on how to re-enable properly the mailbox.

Thanks.

It may just be a timing issue.

But I would try updating the GAL manually to see if that helps.

Also, be sure that your browser cache is emptied just to make sure there are no lingering saved credentials.

Hi,
The issue you may be due to a poisoned mailbox. Exchange 2010 will detect logical or physical corruption in a mailbox and isolate it to ensure it doesn't cause a store failure. Exchange will then attempt to repair the mailbox. If the repair is successful, the mailbox will be unquarantined, which happens six hours after the last failure was detected. You can speed up the process by deleting the registry key which contains the mailbox GUID, after the mailbox has been repaired.

Microsoft was working on a previous case when this happenned (it was in fact caused by them). They fixed it, but don't know yet what they did to fix it. Will try to find out and will post here once I know.
