It would appear that the user has a problem with their MAPI core files.
Here is a repair procedure:
Stop Outlook first!
1. Start Windows Explorer.2. Locate and then open the following folder on your computer:
C:\Program Files\Common Files\System\Msmapi\1033
3. Right-click the MSMapi32.dll file, and then click Rename.
Note: The file (Msmapi32.dll) that you are renaming may differ from the file (Mapi32.dll) that is mentioned in the error message, if any.
4. Type Msmapi32.old, and then press ENTER to rename the file.
5. Start Outlook 2013.
Note: When you start Outlook 2013, the program will repair itself.
