Is your Outlook 2007 running slow ?

Outlook 2007 running slow

        Outlook 2007 uses your existing account settings to create new ones for you. There are 4 files which contain information about add-ins, views, custom toolbars, and custom forms which may be corrupted in the upgrade process. You can safely delete (or rename) these as Outlook will recreate them without loss of data or settings, with the exception of outcmd.dat.






This file holds customized toolbar settings, but since Outlook 2007 uses ribbons, not toolbars, you'll need to redo any customizations anyway.

Extend.dat - 

Windows Xp: This file is located in C:\Documents and Settings\username\Local Settings\Application Data\Microsoft\Outlook.

Windows 7:  C:\user\Username\Appdata\local\Microsoft\Outlook.

Views.dat and Outcmd.dat :

Windows Xp: These files are located at C:\Documents and Settings\username\Application Data\Microsoft\Outlook

 Windows 7:  C:\user\Username\Appdata\local\Microsoft\Outlook.

Frmcache.dat :

Windows Xp: This file is located in C:\Documents and Settings\username\Application Data\Microsoft\Forms

Windows 7:  C:\user\Username\Appdata\local\Microsoft\Outlook.

Keep in mind that unless you customized Outlook or installed custom forms, some of these files may not exist. Also, the folders that these files are in are hidden.


If deleting the files doesn't help, try a new profile.
