Hi

I have a TMG 2010 server acting as a proxy server for all my internal clients.  We have migrated to office365 for mail and everyone can use ok.  I am trying to let our users connect to other office365 prosucts such as sites Skype but even though I think I have added all the domains and ports TMG seems to be blocking as it thinks it anon access.  Even though I have added all the office365 domains to the networking tab to bypass proxy for those domains.

I can access all these sites if I bypass the proxy which makes me think my firewalls are setup correctly.  Has anybody had issues like this?

Hi,

Any information in TMG logging when Skype got blocked?

Please also check ondrej's suggestions in the following thread.
