Hello.
One month ago something strange happened to a mailbox of my Exchange 5.5 Mail Server.
A user told me that he could not send any message.
I logged on using the Outlook Web Access feature of Exchange 5.5 and I noticed some strange long text characters next to the INBOX title heading on the left.
I decided to delete his account and recreate it but when I tried to delete the mailbox, the system refused and displayed the following error message:
“An unexpected, unknown error has occured MAPI or an unspecified service provider ID no: 8004011b-0000-00000000”
After this, I tried to clean the mailbox with the “Tools->Clean” command and it failed, too.
Also, when I tried to check the status of the mailbox size on the server using the special “Mailbox Resources” option I got the same error message.
Now,I do not have the ability to check the mailbox size of all mailboxes on the server because whenever I select the “Mailbox Resources” option I get this error message.
Any ideas what caused this problem and how can I solve it?
Thank you in advance.
