If you install the Enterprise Vault Outlook Add-In, and then later remove it and reinstall to a different location, the following problems occur:

The problem occurs because Outlook maintains a cache file of settings, called extend.dat, which contains a pointer to the original location of the Outlook Add-In.

You can stop the problem from occurring by taking the following steps:

If the problem already exists, the solution is to delete the extend.dat file so that it is automatically rebuilt when Outlook is next started. As the location of this file varies, you need to search for it. One copy of the file exists for each user who uses Outlook on the computer, so there can be several copies of the file to delete.
