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.
