Using Classic Outlook on Windows for personal email, calendar, and contact management
I have just received this from Microsoft support - maybe they can provide more detail to all of us with this problem???
We analyzed the logs and found that the issue you have is something which has been fixed in future update as the updates have already been released to selected group of users
The Outlook version and the build that you have, has not received that particular update yet.
There is not particular ETA as to when the update will be received on your Outlook but once your Outlook gets updated, the issue will be taken care of.
Therefore, we request that as of now, just wait and continue to use outlook as normal and once it gets updated, the issue will be sorted out.
Thanks
