Outlook Desktop M365 error: "This is not a valid file name." when sending email with no attachments
Latest version of Office Desktop - for some new email, when we reply, we get an error message popping up: This is not a valid file name. There is no attachment on the email, we're just replying to t...
We've been getting the exact same error for random internal people. A customer of ours just told us they get the error when responding to some of our emails. It's not all emails and reply's seem to be worse.
Anyone know if the latest update on the 4th January addresses this at all? as the customer in question is running on an RDS I cannot easily update without getting everyone off the system first.
If anyone notices this has vanished at any point, please do update us.

- Hi all,
I upgraded to M365 Version 2112 (Build 14729.20194) yesterday and I'm NOT seeing this problem on older problem emails I had flagged. I can reply to them and forward them with no errors in Desktop Outlook.
I read the release notes on the current channel - https://docs.microsoft.com/en-us/officeupdates/current-channel - and Microsoft mentions several fixes to Outlook where Outlook "...stopped responding when retrieving personas or an unexpected close when loading people photos". I had noticed that some of our trouble email, if looked at in OWA had recipient headshots in the header and in Outlook desktop they did not. Told that to Microsoft support 2 months ago.
Fingers crossed, this is fixed!- Can anyone else confirm that the issues are no longer presenting themselves following the update mentioned?
