Mac 14.2.1 Spamsieve 3.0.3 apple mail outlook mailbox

For the past few days I have been getting the error. “The message [message subject line] could not be moved to the mailbox “Exchange”
The specified object was not found in the store. The process failed to get the correct properties.”

Here’s the log for one of the messages:

What’s going on?

Addendum:

Generally I get the spinning beachball at this point and mail hangs. I have to kill mail. Rarely I can hit OK to dismiss the dialogue box, but not much later another one appears.

The message subjects show as a light brown in Mail and they can’t be deleted manually either.

It sounds like SpamSieve is identifying a spam message and asking Mail to move it to the Junk mailbox, and Mail is asking the Exchange server to do this but encountering an error. Are you able to drag that message to Junk manually?

Please record a sample log from Mail so that we can see what’s causing this.

It sounds like there’s something wrong with Mail’s data store. It may help to rebuild its database.

Thanks for your reply pointing to an exchange server issue.

The messages had been marked by microsoft as spam, that’s why they were brown.

went to the website and instructed it to block the messages and deleted them.

they are still showing on my Mac but I’ll work it from the Mac software side if they don’t go away.
