Trapper Posted January 28, 2014 Posted January 28, 2014 This has been driving me mad for months. Since the latest wave update my Outlook clients on site connect, then disconnect, then connect, disconnect etc. As far as I can tell this does work fine off site - and the connection analyser tool checks out OK. My tenant domain school.bham.sch.uk is also the same as my internal AD domain (also school.bham.sch.uk) - don't ask why it's legacy. I've set all the DNS records up - even typing autodiscover.school.bham.sch.uk into a browser takes you directly to OWA. I've been reading that a very small % of users have had problems with Outlook and the latest wave of O365, but I cannot tell whether I am one of the really unlucky ones or there is something screwy in my internal DNS which I'm too stupid to figure out. Help!
Michael Posted January 28, 2014 Posted January 28, 2014 (edited) It sounds firewall ish to me, the fact everything works outside of school talking to Office 365. I don't believe it's DNS, as surely it wouldn't connect at all, but connecting and instantly disconnecting does sound like a firewall issue. This is what you're looking for: POP setting Server name: outlook.office365.com Port: 995 Encryption method: SSL IMAP setting Server name: outlook.office365.com Port: 993 Encryption method: SSL SMTP setting Server name: smtp.office365.com Port: 587 Encryption method: TLS Hope this helps! Edit: It might be because Microsoft previously used different server names, whereas now they're standardised and have been for quite some time. Edited January 28, 2014 by Michael
dezt Posted January 28, 2014 Posted January 28, 2014 I remember having that issue before we got the upgrade, our issue was related to the LA internet and the filters they controlled. As soon as we went with a different provider everything worked fine.
Cache Posted January 28, 2014 Posted January 28, 2014 Do you use a proxy server? Is the Bypass Proxy Server for Local Addresses box ticked? Try unticking it and see if that helps which was the answer to my issues in this thread: http://www.edugeek.net/forums/cloud-services/124386-office-365-outlook-connectivity-through-proxy.html
Trapper Posted January 30, 2014 Author Posted January 30, 2014 Hmm bizarrely it works from our partner school who are part of the same LEA network. This has to be a DNS issue, but I just can't see it. There aren't that many DNS settings to get wrong, and I've triple checked all of them!
Trapper Posted January 30, 2014 Author Posted January 30, 2014 It bloody well is the bypass proxy! How the hell this has occurred is beyond me! Well I've been meaning to setup a PAC file for years, got no choice now.
