Cannot FETCH message S: B00000007 OK EXPUNGE completed.

Sometimes I get a email I cannot FETCH from outlook.office365.com with imap and I have to delete it with Outlook or similar. The email looks OK in Outlook. The email is written in Norwegian. Has anyone had the same problem? Is it some charset that needs to be set in the Client? Here is the log:

That log doesn't seem to be from this module, as that format for the request IDs is not used by this module.

Anyway, I think the server is telling you that there is only one message (and there is, judging by the * 1 EXISTS sent by the server during mailbox open) so when you ask for the first two messages in the mailbox, it of course gives you an error.
