    I finally found the poblem.

    There was Microsoft Office Desktop Apps installed by default with the new PCs in the master that causes the problem. Even if Microsoft Office was installed properly in addition, it caused the problem. Uninstalling it resolve the issue.

Hello Phil,

The interesting message is "Unable to perform a MAPI Logon".

What Outlook version? Is it by any chance a 'click to run' version? If it is, you need client 12.4

If you have a client pc which is working, can you have one of the employees having the issue logon to there, open Outlook, see if that works? It might be that there is 'something' on the new pc's preventing proper loading of EVclient. The KB article in the log references a local install of ESM, which is unlikely, but worth a try.
