We have a 3rd-party helpdesk tool, Altiris, which uses an account to login to the mailbox and monitor messages every few minutes. The content of the messages is then inserted into a helpdesk ticket. Up until SP2, the messages were being inserted as plain text. After SP2, it appears it is being inserted as HTML thus making the notes effectively unreadable.
Regarding the SP2 upgrade, it wasn't uneventful. We began with SP1 RU4v2, and went direct to SP2RU4. There was something on our CAS servers which didn't play nice with SP2RU4, and after a PSS case was logged, it was advised to remove RU4 only off CAS, leaving it on the separate HT servers and MBX server. The issue caused the address book service to continually restart on the CAS servers. The only 3rd party software on those servers is Symantec Endpoint Protection and LiveVault backup services; both of which are also on the HT & MBX servers.
Since the problem only began after the SP2 upgrade, where can I change this back to plain text encoding for this mailbox?
