Outlook could not create the work file

Last reviewed on September 23, 2013

The “Outlook could not create the work file. Check the temp environment variable.” error is more common after an upgrade of the operating system. It’s the result of a corrupted temporary internet cache variable, possibly caused by the upgrading the OS or using Easy Transfer to move settings to a new computer.

Fixing it is easy – you can either edit the registry to change the location of the Temporary Internet Files or make the change within Internet Options (Control panel).

If you don’t want to edit the registry, you can use the Mr. Fix it in You receive an “Error 1606″ error message when you try to install or remove a Microsoft program. Mr FixIt will reset all User Shell Folders values, including Cache.

Edit the Registry method:

At Start menu, Run (or Windows key + R) type

regedit

Browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\User Shell Folders

The Cache variable (in the right pane of the register editor window) should be as follows:

Vista or Windows 7:

%USERPROFILE%\AppData\Local\Microsoft\Windows\Temporary Internet Files

Windows XP:

%USERPROFILE%\Local Settings\Temporary Internet Files

Double click on the Cache name to open it then edit it, entering the correct path (as listed above).
