Exchange 2007 on VMware with a Fibre SAN. Clients about 200 users on, Outlook XP, 2003, 07 and 2010, 50 BB's, 1 iPhone. Recently we started to have performance problems we noticed that some users where not in cashed mode and switched about 10 users back to cash mode yesterday, that totally crippled our Exchange server. Started monitoring and found that PhysicalDisk, Avg. Disk Queue Length is between 0 - 5, and users and BES are complaining.
I did some googeling and found someone had problems with Mac's and Entourage but no Mac's, I had the iPhone turned off temporarily, no change. Right now I'm thinking to create another Drive with a new Store and start moving users to the new Store, maybe some corrupt e-mails? Any other ideas? -- Stefan Jafs
