Exchange 2010, SP3 Update Rollup 6; Running Virtually (VMware) Server 2008 R2, SP1
2 servers - CAS, and MB, no DAG
800 Mailboxes, 14 Mailbox Databases. Largest is 421GB, other sizes are 208GB, 118GB, 114GB all others are under 100GB.
Users in the largest MB DB are experiencing Outlook performance problems:
- Outlook not responding for 1 to 60 seconds.
- Outlook stalls or hangs for just a few seconds when drafting a new email.
- Outlook disconnects and prompts for login credentials.
One thing to mention: - we have recently configured all users to use Non-Cached mode. While I suspect this to be the cause, we need to retain this setting because we run Outlook on Virtual Desktops and cannot have caching enabled.
I'm just wondering what is the best method to optimize Outlook performance?
A. Move the largest MB DB to another volume on the same server?
B. Move the largest MB DB to a new server?
C. Build a secondary CAS server?
D. B and C above?
E. Another suggestion?
Thank you.
