Damn Glenn!  That is some serious BAS(tm) you got there! 

Have you tried disabling the AV software for a start?  Have you considered
SP3 for Exchange?  Are you aware you are vulnerable to MSBlaster running W2k
SP2?

Subject: Strange behaviour after running ISINTEG

All,

Recently we have been having some strange behaviours with user mailboxes,
such as users being denied access to folders in their mailboxes, rules
disappearing etc.  After running ISINTEG on all stores (approx 20), a number
of errors were found and fixed...all good so far.  After remounting the
stores everything looked fine....until the next morning when people came
back to work.

A number of mailboxes had suddenly a LOT more mail in their inboxes and
deleted items folders, some users over 200mb worth, which threw a lot of the
organisation over the store limits and stopped them sending and receiving
mail.  We temporarily increased the store limits to cope with the problem,
however we are still at a loss to explain what happened.

After speaking with PSS, they are also at a bit of a loss as well. I've also
checked Technet and other online resources, but no mention is made of this
sort of problem.

- Some users had no effect on their mailboxes
- Some users had lots of mail return to either their deleted items or inbox
(we are surmising that the way the message was originally deleted has
determined where it came back to - shift-delete - back to inbox, deleted via
deleted items - back to delete items).
- The restored messages don't seem to be from the previous days. In all of
the cases we have confirmed, messages deleted the couple of days previous
didn't come back, but messages deleted prior to that did come back.

Has anyone seen this behaviour before and could possibly explain what
happened ? As with all of these things, the people most affected were senior
management, and they are screaming for a satisfactory response.

Config:
Windows 2000 SP2 with hotfixes
Exchange 2000 SP2 - 6 Servers, 2 badly affected, 1 with minor effects, 3 not
affected at all Trend Scanmail installed on all servers
1 Storage group on each server, between 2 and 4 databases per storage group

On the servers that were affected, only one or two of the 4 stores was
affected.

As far as we can determine, either Exchange wasn't properly cleaning out
deleted items from mailboxes (but was reducing the size of mailboxes as
users were under the mailbox limit cap until the messages were restored), OR
something happened and exchange replayed some of the transaction logs
restoring old messages (but in that case all of the stores in the storage
group should have been affected, but weren't)

Thoughts ?

TIA

Glenn Corbett
