Here’s an issue I experienced recently (not really sure what caused it), but as I’m sure it happens to others as well I decided to post a quick solution that worked for me.
For some reason Outlook 2010 (on Windows 7 Enterprise SP1) wouldn’t launch. I mean the application would start, but the window wouldn’t open to full screen and would therefore become useless. Luckily, while tinkering around I came across a solution (one that I subsequently found on several forums as well).
Here’s what to do should your Outlook “decide” not to open to full screen.
1. With Outlook closed right click on your Outlook shortcut icon, click on Properties and change Run: field to Maximized
2. Start Outlook
3. With Outlook running right click on the task bar and click on Cascade windows (this will momentarily re-size the Outlook window to a smaller size)
4. Restart Outlook (this is more of a test to make sure it worked)
That should do it!
