I can only connect with POP3 to our Office365 account and when I try to delete an email I get the message:
No X-UIDL header found
If I understand the documentation correctly this is necessary (among other things) for deleting emails.
Is there a reason why Mailman isn't getting any X-UIDL headers from Office365 and/or is there another way of deleting emails?
