Outlook 2007 Will Not Start
MS Outlook 2007 is one most popular e-mail clients used by businesses and individuals around the world. Because Outlook is packaged with the Microsoft Office Suite, it shares a lot of important dynamic link library files with other applications. If one of these shared DLL files becomes damaged or corrupt, several applications including Outlook will stop working properly. One of the shared DLL files most prone to problems is msvcr80.dll. This file is used by both Outlook and Power Point. When this file becomes damaged, neither application will open and the user will be shown the message:
Msvcr.dll is corrupt or missing
This file can become corrupt if an application that is using is not closed properly or the computer crashes while the file is in use. Replacing the damaged or missing msvcr.dll file can be accomplished by repairing the Microsoft Office Suite in the Add or Remove Programs window.
Because msvcr.dll works directly with the Outlook PST file, the PST file often becomes corrupted and Outlook will still be unable to open after the DLL file has been replaced. The PST file can be repaired using the Scanpst.exe utility located in:
C:\Program Files\Common Files\System\MSMAPI\1033
In the Scanpst.exe interface, browse to the PST file and click the Scan button. The utility will automatically repair any damage it finds. If Outlook continues to have problems, a third party Outlook PST Repair application will be required restore the PST file to a functioning state.
