Outlook Cache Mode Cleanup

I have come across many users either wanting to know how to manually update the GAL, various issues with exchange cache mode, and outlook running slow. One of the fixes I have always used is to cleanup the profile on the client workstation. So I figured I would post a small little guide for Windows XP and Windows 7 on how to cleanup outlook in exchange cache mode.

Windows XP

Open up Outlook

File > Account Settings > Email Tab > Change

Remove Check from Use Cached Exchange Mode

Close Outlook

Navigate to C:\Documents and Settings\*User Profile*\Local Settings\Application Data\Microsoft\Outlook

Create a Folder Called Junk

Move everything into the Junk Folder (***Exclude the .OST file***)

Open up Outlook

File > Account Settings > Email Tab > Change

Add Check from Use Cached Exchange Mode

Close Outlook and Reopen

Windows 7

Open up Outlook

File > Account Settings > Email Tab > Change

Remove Check from Use Cached Exchange Mode

Close Outlook

Navigate to C:\Users\*User Profile*\AppData\Local\Microsoft\Outlook

Create a Folder Called Junk

Move everything into the Junk Folder (***Exclude the .OST file***)

Open up Outlook

File > Account Settings > Email Tab > Change

Add Check from Use Cached Exchange Mode

Close Outlook and Reopen

This procedure will remove the currently downloaded OAB (Offline Address Book), and cause outlook to download the most recent OAB. If you are having trouble with the GAL (Global Address List) updating across all users you can refer to the article below which discusses how to Fix the GAL on exchange and update the OAB across all workstations.

I understand this would take a long time for larger companies but is very helpful for when you get those handful of users with outlook issues.

Thank you and if you like my article please check yes if it was helpful :).

Best,
