We just finished a migration from Microsoft Exchange/Office 2003 to Microsoft Exchange/Office 2007.
Now many users are experiencing Outlook 2007 browsing hangs and typing delays in emails.
The browsing delays are from 2 to 15 seconds. After the delay, Outlook may be responsive for 2-10 minutes before it hangs again.
The typing delays may be up to two or three words and also are random.
Exchange 2007 is on a Dell 1850 2x 2.80GHz CPU's w/ 4GB ram & Server 2003 R2 Standard x64 SP2 OS. It has a Dell PowerVault 220S 1TB DAS SCSI array for the Exchange data drive.
Clients Outlook 2007 are on XP Pro 32 & 64 bit SP2 OS's w/ 2 & 4GB ram.
We have 125 users on a 1GB network and many users have Business Contacts Manager for Outlook as well. This is the only Add-in we add.
Any ideas on what may be the issue?
