Outlook multiple errors - multiple users All work in OWA 0x80070057-0x00000000-0x00000000

Have several users who are getting this error when sending message to multiple recipients

Error is [0x80070057-0x00000000-0x00000000].

Failed to upload attachments to server (error 0x80070057).

Submit-Message failed: message id(17), failure enum(29), HResult(0x80070057), EC(0).

Also seeing the errors when opening a message that message has been changes. Do you want to keep changes?

Thirdly, some users cannot forward meetings to users. they get: "! Unknown Error." popup. This is for internal and external meetings.

All of this works in OWA, so I believe these to be Outlook issues.
Perhaps a recent update is causing this?

Hi @SteveHull-7215 ,

I noticed that the new version has been released. Have you ever updated your outlook to the latest version as this ariticle said? And have your issue already been fixed?

If you have any updates, please feel free to post back.
