Outlook crashes every time it sends an email or accesses the Global Address List

Filed in Outlook 2010, Outlook 2013Tags: , , , , ,

I had an Outlook 2010 client today that would crash every time the user tried to send an email, click Check Names (ctrl-K), or update the offline address book. Sending or checking names would generate the typical Windows 7 error message saying, “Microsoft Outlook 2010 has stopped working. Windows can check online for a solution…” Attempting to download the offline address book just caused Outlook to stop responding.

The solution was to start Outlook with the CleanAutocompleteCache switch:

Outlook.exe /cleanautocompletecache

    I’m glad to hear a solution for 2013 has been found but how does an “average Joe” (non-techie) like myself, implement this fix?

    Hi Raymond.

    First, make sure that Outlook is not running. Then, on Windows Vista or 7, click on the Start button and type “outlook.exe /cleanautocompletecache” then press Enter.
