I have a client using Office 365. They have 39 accounts, and they have all
been in use for about 9 months.
This morning one of the users says "no one has been able to e-mail me for
several days".
She was able to get the remote user to forward me details.
Apparently the remote user is a Hotmail user. The delay notification is
beyond useless. No information about message IDs, or mail server responses:

So I figured I would look at the "message tracing" feature of Office 365.
Maybe it's just because I'm connecting from an evil Linux system using
Chrome, but there appears to be no way to put a 'recipient' in to their
wizard. You can add a Message ID and a sender--just no recipient.
(Javascript console was full of 401, 403, and 500 errors)
Putting the proper sender in returns no results.
I tried e-mailing a test account at the affected domain. The message came
through almost immediately, but message tracing showed no results.
Does anyone know if Office 365 logs messages that are rejected or delayed
as part of spam filtering?
I know in Exchange 2007 (or maybe it was 2012) that rejected messages were
never logged unless you turned on protocol logging.
Thanks,
-A
