Subject: [Imap-protocol] Exchange IMAP service dropping sessions after 9

errors

I have observed that the Exchange IMAP server will disconnect an IMAP
|
|
session after 9 errors (such as issuing an EXAMINE command on a
|
|
non-existent mailbox or trying to append a message with an invalid
|
|
internaldate.
|
|
|
|
I've seen this with Exchange 2007 but the limit may exist in new
|
|
versions as well.
|
|
|
|
That can represent a problem during migration of a user account since
|
|
during copying thousands of messages it is unreasonable to hit the error
|
|
limit and get blown away.
|
|
|
|
I have modified my migration tool to deal with this by counting the
|
|
number of NO or BAD status returns, disconnecting & reconnecting, and
|
|
then resuming from the point of error.
|
|
|
|
However, I would like to ask if anyone knows if the error threshold is
|
|
configurable in Exchange.
|
|
|
|
Thanks,
|
|
Rick
