I recently did some fresh installs of office 2007 standard for a client. Now the client is experiencing some minor issues where when they go to do something (such as attach a file or really do just about anything) in outlook it will freeze on them temporarily freeze and the program will appear as non responsive. Outlook will hang for 5-10 seconds and then it will resume and they will be able to continue working. The computers can handle outlook 2007, so the issue isn't with not enough RAM/HDD space/etc.. They are connected to Small business server 2008 64 bit using the built in Exchange 2007. Exchange is acting as an SMTP and pop connector, collecting email form a third party and distributing it to the appropriate mail box. Outlook is set up with 2 accounts the exchange account and another pop account. All of the end user computers are using the latest version of Kaspersky anti virus as their AV program. Any ideas to why outlook is freezing?
