Why am I getting this error when the message does exist?

Question

I just started getting the following message on Monday (I have been using web based Outlook for a year): "This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later."

I can send the same email message to single or multiple email addresses without a problem so I know the message exists. It only occurs when I try to send to one of my groups.

I have tried using 'To', 'cc' and 'bcc'. I have tried forwarding the message. I tried to send again this morning.

Any ideas?

Answer 1

Hello, I am having the same issue.

Very interested in the solution.

Thank you

Answer 2

Did we find a solution to this? Is it just a backend Exchange problem?

Answer 3

This is a major issue with me as well

Only when sending from shared mailbox

Unclear if it has something to do with an attachment, of emailgroup, and only in Exchange (Outlook for web) in O365.

This message can't be sent because it no longer exists. It can only be discarded. Make sure you copy the contents of the message before you discard if you want to use them later."

And the body of the email is gone when verifiying in the sycned draft in Outlook web app.

Only occurs with Exchange (Outlook for web)
