    Greetings XBedoya !

    McMapi.dll is McAfee Spamkiller. Disable McAfee Spamkiller and test if problem persists.

    1. If no joy, reset the Outlook toolbar template. With Outlook close, do a search for and rename outcmd.dat file. Do the same for frmcache.dat and outlprnt files. Restart Outlook.

    Outcmd.dat is located in C:\Documents and Settings\<user>\Application Data\Microsoft\Outlook folder. It is a hidden file, so you have to unhide hidden files. Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders". Click OK.

    2. If no joy, register two important Outlook files. Go to Start > Run and type regsvr32 OLE32.DLL
    Do the same for INETCOMM.DLL

    3. If no joy, an addin could be interfering. Disable Outlook Addins.  Do a search for and rename extend.dat file.

    4. Check if an external program running in the background is interfering with Outlook. Check Firewall, antivirus, antispyware, antispam, and all Norton programs. Disable these programs one at a time.

    5. If no joy, create a new Outlook profile.

    6. Repair Outlook. With Outlook open, go to Help > Detect and Repair.

    7. If no joy, reinstall Outlook.  Go to Add/Remove Programs and highlight Microsoft Office. Click on Install/Uninstall.  A menu will pop allowing you to choose repair or reinstall.

    Hope this helps, war1
