I have recently moved all mailboxes off one Exchange Server onto another, so that I could safely run ESEUTIL (the server had not been backing up for some time). After the successful tidy up of the server, I then moved the mailboxes back - all appears fine except for the following frequent Warning entry that appears in the event log:
Event ID: 1033
The rule (#NET FOLDERS#) with sequence number 0 is being ignored because it is disabled.
I know it appears a self-explanatory message, but I have no idea why they have suddenly appeared.
I am running Exchange 5.5 / SP3.
