Michal, at the time of writting this, the web interface for the mailing lists gives a not found error.

The fact that the log mentions an SSLv3 connection attempt, rather than something more modern, might well indicate what you suspect - I would be very surprised if the O365 email service still accepted SSLv3 connections.
Hi,
it has been told earlier (at least by me), SSLv3 in the logs means nothing. It might be deceiving, but those lines aren't telling the TLS version being used.
The hint indicating it is where it says "TLS_[version] ciphersuite:".
On that log it doesn't even appear because they couldn't even negotiate them.
Could it be by TLS version?, maybe.
Ben, try Thomas advice setting in your service:
sslVersion = your desired version from what manual tells
Without know that service settings, is the only advice to give, I think.
Regards.
P.S.: thanks Michal for fixing the web interface of the lists, even though I see missing mails.
Have you been cracked?
