I'm still confused and don't understand of why my Exchange Server 2007 SP1 transaction log always fills up quickly when the Symantec Enterprise Vault 8.0 SP4 executes the weekend archiving job ?
in my previous diagnostic steps I have done the following actions:
1. Pin point the shared mailbox (SharedMailbox1) that cause the problem in Storage Group 1 and then move the Shared mailbox onto Storage Group 2, after several weekend yes the problem arise again in the Storage Group 2.
2. Export the old SharedMailbox1 content, disable the SharedMailbox1 (mark as delete), create new one with the same name (including aliases and its permissions) and then importing the exported content into the new one.
Somehow the transaction log still growth uncontrollably and always 90% full in the weekend? in which I believe there were very low email traffic in my company.
Any suggestion and help would be greatly appreciated.
