Environment - CAS Array - with 2 CAS/Hub Transport servers. DAG with 2 MBX servers.
Issue - just a couple of users have an issue where their outlook will stop communicating with exchange, usually when sending a messasge. The outlook client does not freeze up, it gets stuck on status updating.
When viewing the users mailbox, via EMC the properties dialog box will freeze when checking the "Mailbox Features Tab". Also when tyring to move the mailbox to another DB store it times out.
Can not find any related errors in the logs at the time of the issue.
update - The re-created profile did not help. Nor did SCANPST. It appears that the issue occurs after a big update to the mailbox, for example.. the user deletes 300 messages in their inbox. The client then hangs on status - "updating"
