Outlook 2007 opens (or not), then freezes

I have been running Office 2007 since loading getting my laptop with Windows 7 2.5 years ago with no problems. Just recently Outlook has stopped responding. Symptoms include:

1. Frequently won't launch, open task manager to see an Outlook.exe process is running though application is not open. End the process application will open.
2. Once open can only do 1 thing before the application freezes again.
3. Re-open task manager and the Outlook.exe process is running using 40K + in memory.

Have re-installed the application but this has not helped.
I have run Advanced System Care and Slim Cleaner along with full scans on Avast and Malwarebytes.
Have run the Office Diagnostics a few times and get no error message.

Because of how it fails to open or freezes just after opening I feel like a start up file is corrupted or something - but the re-install didn't help.

Any suggestions?

When you say you re-installed Office 2007, did you uninstall it first?

Something is obviously wrong with the current installation, so I would be inclined to uninstall Office 2007, reboot your computer, and then re-install Office.

Yes, I uninstalled first.
