My issue:
The journal inbox is not processing emails fast enough.
My setup
Running Enterprise Vault 9.0.2 on Windows server 2003
Running Exchange 2010 SP3 Rollup 7 on Server 2008R2
1 journal mailbox
3500 user mailboxes
My problem
The journal inbox contains about 20000 emails at 8am in the monring. During the day this number rises to 75000 and then overnight it may drop down to 18000-20000 - then it all happens again (on a daily basis).
This has only started to happen in the last 3 weeks.
Things that I have noticed and tried to adjust
We have migrated a lot of users to Office 2013.
I can see in the logs that it is trying to expand distribution lists in our global environment, no local ones - Event ID 3257.
We have archiving set to run from 6pm to 6am every night.
I have changed the "Closest GC" and "DS Server" registry entries to "1" and "local GC" respectively
In a DTRACE I can see:
CEVFilterController::ProcessAllFilters - Time Taken to Process External Filter [EnterpriseVault.CustomFilter]: [1.053366] seconds

Any ideas on how I can fix my systems
