This morning I opened Microsoft Outlook 2007 and got the
error "Cannot start Microsoft Office outlook. Cannot open the outlook
window"
No system changes have been made, no anti-virus software is running.
The easiest way to remedy this is to go into Control Panel > Mail > Show Profiles…
- Select your current profile (probably only one profile in the box)
- Click “Copy” and type a new name
- Set the new profile as the default profile under “Always use this profile” at the bottom
- Close this and then restart Outlook 2007
Exactly one week ago, Automatic Updates installed “The 2007 Microsoft Office Suite Service Pack 2”, which I believe has introduced a pretty serious bug into MS Outlook 2007.
