Outlook wont run up, mail control panel applet says I have run out of resources

Environment:
Windows 7 Professional, Outlook 2010

I have been using Outlook for a couple of hours without issue. I then rebooted my machine and went to run Outlook and received an error dialog with "Cannot Start Microsoft Outlook". I then tried to run outlook in safe mode:

  • outlook /safe
  • outlook /safe:1
  • outlook /safe:3
  • outlook /safe:4
  • outlook /resetnavpane

Nothing worked so I tried a repair of my Office install, followed by an uninstall of Outlook and a re-install. Still no joy.

I then attempted to open up the "Mail" control panel applet and receive a warning dialog of  "Your system needs more memory or system resources. Close some windows and try again."

As this is a fresh boot and the machine has 3GB of free RAM resources is not the problem. I suspect I have a corrupt profile. Can anyone shed any light on this for me? Anything I can try? I was hoping that Outlook was going to prove more stable than in the past with more informative error messages *sigh*.

I renamed the HKCU\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem to "Windows Messaging Subsystem OLD" (no need to do anything in HKLM in my case).  Then I was able to open the "Mail" Control Panel and create a new profile.  Nice one!

You have two options: completely uninstall office and reinstall - delete all office files from the hard drive, all registry keys. Actually, since it works on the other system, deleting *all* outlook registry keys and repairing might fix it.

If you aren't in a hurry and want to try different things - delete the windows messaging subsystem key in HKCU and HKLM and repair. If that fails, delete it and all outlook keys you can find then repair.
