Hi rbic102,

You’ve to do a small modification in the system registry to get your Windows mail back to work. Before you do this step, did you try running Windows Mail in administrator mode. Right click on Windows mail and click on Run as administrator. Check if Windows mail opens without any problems.

However serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
