Then again when trying to add a new Calendar appointment. After a little bit of research we came up with the solution.

How to fix the Outlook Not Implemented error
It turns out the issue was caused by a recent upgrade from Office 2013 to Office 2016, during the upgrade the old version was kept, so in effect the upgrade process was just a new installation. One would assume installing a newer version of the same software would result in the old version being removed, not so.

To solve this issue you will need to remove the old version of the software.

The first time you open outlook it may take a little longer, just wait.

Another issue we noticed once Outlook was started was that some favourites were removed from shared mailboxes, these just simply need to be re added.

 

If you experience this issue and the above doesn’t work for you then it may be due to another reason, we found a few in our research, too many to add to this post.  Give us a call if you need assistance.
