Error in Outlook when opening messages

Sounds like a problem with norton antivirus maybe ?

"C:\Program Files\NavNT\vpmsece.dll could not be installed or loaded. It may be missing or there may not be enough resources."

Solution:
There are four options to solve this problem. They are listed in decreasing order of preference.

Replace the missing Vpmsece.dll file:
Use Search to locate the missing Vpmsece.dll file. If the file is found, continue with the next three steps. If the file is not found, continue with the next section.
1. If the error message referred to a specific location, copy the Vpmsece.dll file to that location.
2. Copy the Vpmsece.dll file to the Outlook folder. The default location for Outlook is:
C:\Program Files\Microsoft Office\Office.
3. Restart Windows.

Delete the Extend.dat file, and then restart Windows. The Extend.dat file will be rebuilt.
For more information, see the document Error: Unable to load .dll. You may be out of memory, out of system resources, or missing a .dll file.
Delete the local user profile or the local mailprofile for Outlook (2000/XP only).

NOTE: This only applies if the problem does not occur on the workstation when you logon as a different user that has NOT logged on to this workstation before. Upon next log on, you will be presented with a new profile and default settings. Before doing this, make a backup copy of the profile (C:\Documents and Settings\).

Remove the NAVCE 7.xx add-in for Microsoft Outlook.

To remove the add-in for Microsoft Outlook:
1. Open Microsoft Outlook.
2. Click the Tools menu, and then click Options.
3. Click Other, and then click Advanced Options.
4. Click Add-in Manager, and then uncheck LDVP.
5. Click OK to exit, and then restart Outlook.

Hope that helps you.
