WHAT TO TRY
Not Enough Available RAMYou can make more memory available by quitting all programs, restarting Windows and then only starting those programs that you require. You can use the Windows Task Manager to view and selectively shut down programs that you do not need.
To view all running programs press CTRL+ALT+DELETE. Click the program you want to shut down and click End Task.
Not Enough Available Swap File Hard Disk SpaceWhen Windows runs out of RAM, it uses hard drive space to free more RAM. It does this by swapping information from RAM to the swap file on your hard drive. Normally Windows manages this process without user intervention, however, if you run too low on hard drive space on the drive that contains your swap file, Windows cannot free enough RAM for normal program operation.
If you have multiple disk drives, you can use the My Computer Properties to determine which disk drive contains your swap file.
To make more disk space available empty the Recycle Bin and then use Windows Explorer to delete any files you do not need.
Invalid Extension InformationOutlook may have problems with incompatible or invalid extension information. Extensions may cause Outlook to not start or generate errors while running.
