Outlook: Cannot move the items. The operation cannot be performed because the message has been changed.

Okay so I did this and it seems to have fixed it for me. I use 365 too and this issue has been driving me bonkers.

When I set up 365 I added four accounts. Added their passwords etc.

I had already unchecked the 'when a reply modifies the original" and it didn't fix it.

I went to File>Account Settings>server settings for each account and found I had to-for some unknown reason- re-provide all my account approvals/passwords.

I then went to File>Account Name and Sync Settings> and UNCHECKED "Purge items when switching folders online"

On the same screen, I have "Mark items for deletion but don't move them automatically" checked.

I had previously checked and unchecked every other setting I had to no avail.

However on sending myself an email using the above combo-I was now able to archive, move, delete or move it about with no issue.

I am still showing all my labelled/categorised emails set up in Gmail web with no issue.

I then went to have a celebratory coffee, using choice words under my breath.

SHame, I have always had those - and many of the other folder/labels hidden but not being able to move a message without moving off it is still a problem...

Amazing. Thank you SO much for this!

I had been fighting with this issue for SO many years. Reported countless times to M$ but never a (useful) response, just the usual stuff like we saw in this thread.

For me it would always happen after saving an attachment from an email then trying to move the original email. Usually clicking another email and then back to the original would work, but worst case I would have to restart Outlook. SUCH a pain.

Switched those two folders off in IMAP yesterday and no problems since. Fingers crossed...

Thank you for your description of the "workaround" which worked for me. Like others on this thread, this issue appeared for me after I switched from POP to IMAP. It appears to be related to reading a message in Outlook (which changes its status from unread to read), but the change in status hasn't been forwarded to the server version yet. It seems to be that switching to another message (or in my case, switching to a message in another folder) "frees up" the message to synchronize between Outlook and server; so that upon returning to message, the message can be moved without the notice.

Unlike other posts suggest, this appears NOT to be related to Exchange (since I do not have any exchange accounts), but IS related to IMAP.

I keep seeing this issue, too. I always need to restart Outlook for this, it's terribly annoying and costs a lot of time. It's ridiculous that a problem like this exists and hasn't been taken care of, yet. Microsoft should finally address this.
