I'm an admin and ironically my mailbox has frozen up this morning.  I was using IMAP via Outlook when it happened, but nonetheless it won't even open in a browser now either.  Outlook shows my inbox with lines through the two emails I was trying to delete two hours ago.  If I try to logon to webmail it attempts to open, showing the folders to the left, but the inbox stays empty showing one unread message to the left.  There are several messages showing in the queue and most if not all are mine.

 

We have tried ending session for my online user, but the last one will not end no matter what we do.  I now show two new anonymous activity from my IP as well that weren't there either.

 

Any help would be greatly appreciated!
