We are migrating from a Scalix email system to Office 365, andI'm testing all functionality before go-live.
We gave up on ADFS because when we implemented it, it broke, then locked out all our 365 accounts for 5 days, so we're just using password sync.
I've created all my local DNS entries, as well as the DNS entries with my hosting provider. Lync connects without any issues, and autodiscover works on Outlook 2013 (sometimes). It fails with Outlook 2007 and 2010, and with certain users, won't work on 2013.
All necessary ports on our firewall are open.
I can get it to work with my account on Outlook 2013 every time, but if I try my account on Outlook 2007 or 2010, it fails at autodiscover.
I have a user that wouldn't configure on 2013 either, unless I did it manually.
If I do an nslookup on autodiscover.mydomain.com, it points to 365:
