Exchange under Mountain Lion

I have major problems using Exchange in Mountain Lion. Under Lion everything worked fine (Mail, Calendar, Contacts incl. global address list). Under ML only Calendar works, Mail and Contacts show connection errors. Our corporate server is Exchange 2007.


Has somebody a fully working Exchange in ML?


Any ideas?


Many thanks!

Fixed my problems (unable to download old email) only new were coming down from exchange.


1. Open up terminal go to /Users/myLoginName/Mail, there should a folder V2. make a copy. (better to be safe then sorry)

2. Close down Mail/Calendar app and remove any server setting you have for exchange in the Mail, Contacts & Calendar settings in System Preferences.

3. Delete or better yet move /Users/myLoginName/Mail/V2 folder out to some other location.

4. Create new mail setting in System Preferences.

5. Open up Mail app and if mail doesn't start to come down uncheck Use Autodiscovery service and click on Advanced and uncheck use SSL.


Hope this helps, I've been fighting with this for a few days.

For what it is worth...I had a similar problem that I found a resolution.


For a little history, in the past I connected to my work Exchange server via Apple Mail and had connectivity problems while trying to connect externally (I did not want to VPN in everytime I wanted to get my Exchange mail). For whatever reason, the workaround that succeded with my Exchange was to put the external server address in both external and internal server address boxes.


Everything worked fine until I upgraded to ML and it broke again. I could get Exchange to connect via VPN, but it would not connect to the external server (after shutting down VPN). I noticed that there was a new option for autodiscover in Mail.app v6.0, which worked flawlessly when first connecting to my Exchange account via VPN. But I could never connect without VPN whether this option was unchecked or not. After messing it with for many days, I noticed that the mail activity window showed that mail was still trying to hit the internal server address, even though I was not connected to VPN (should have been trying to connect to the external server).


I remembered my previous problem, and so I configured my Exchange server settings to the external server address in BOTH boxes again (and then unchecked autodiscover). Bang, connected immediately with no problems. My guess is that Apple probably does not have autodiscover talking to Exchange the way MS likes. I might have issues if I try to connect to Exchange via VPN, but I don't care since the intent is to connect without having to VPN-in everytime I wanted to check mail.


This might not work for everyone and your personal demands might need both internal and external servers working, but if you want to connect to Exchange externally and ML broke your connection, this workaround might be worth a shot.

The inbox of Apple Mail did not sync with my Hosted Exchange Account after upgrading to ML.


Now i've found a solution:


  • i started Windows Outlook 2010 in my virtual machine
  • then went to the account settings of my Exchange Account
  • looked up the https:// adress of my exchange server in Connection Settings / proxy
  • disabled autodiscover in apple mail
  • inserted the servername from windows outlook 2010 in to internal AND external server, withouthttps://
  • Now Apple Mail is up and running with my Hosted Exchange Account !!!


Nochmal in Deutsch:


  • Ich habe in Windows Outlook 2010 gestartet
  • in den Konteneinstellungen den Servername gesucht: Weitere Einstellungen/Verbindung/Exchange-Proxyeinstellungen
  • Feld "Diese Url für die Verbindung mit dem Exchange-Proxyserver verwenden:"
  • Den Servernamen, der nach https:// steht kopiert
  • Automatische Servererkennung in Apple Mail deaktiviert
  • Den Servernamen bei Interner UND Externer Server eingetragen
  • Läuft


I hope this is also a solution for you folks 🙂!

With the options in 10.8.1 I can get mail working - just need to edit the settings afterwards, turn off autodiscovery and add the correct hostname again. Calendar does not work, and trying to access account settings inside calendar results in an immediate hang.


10.8.2 has the same behaviour - I deleted the account, removed some files, rebooted and readded the account: Mail still does not work without the same manual intervention as in 10.8.1, and nothing can make the calendar work.

Sep 19, 2012 6:26 PM in response to fthomas21

I just updated to 10.8.2 today and got everything working. After the update, I tried working with different settings and still had to use my other mentioned workaround to get it to work. However, I tried one more time and completely deleted the Exhange account in System Settings and reinstalled the Exchange account. I had to VPN in order for the account to setup.


After I got it reinstalled, I went to mail and made sure Autodiscover was checked and that the internal and external servers were both automatically configured. I disconnected VPN and low and behold, it works great both internal (VPN) and external (VPN client disconnected).


Not sure if this is directly related to the 10.8.2 update, but it is working perfectly for me now after several months of problems and workarounds.

10.8.2 BLEW UP MY NOTES .. no longer syncs with exchange.. any ideas.

I've updated to 10.8.2 and still exchange does not work. It still downloads the headers and folder trees but when I click on an email it never loads. I have tried deleting the account from keychain, settings, etc but still does not work.


Is this a problem Apple have acknowleded as it seems to gave been going on for a long time now and I would have thought there is a huge market of business users this would be impacting (if they do not go down the Outlook route)?

Sep 20, 2012 7:54 AM in response to simwit

I had this problem too. It suddenly went away, though. Only thing that happened was that our Exchange admins noticed that the indexing service process on the Exchange server had gotten hung and needed to be killed and restarted. It's unclear if that was somehow related to the problem (perhaps Mail.app's exchange implementation makes more direct use of it than others?) but you might ask your admins to check that.

After iOS 6 came out I decided to make the jump from Outlook for Mac 2011 to Mac mail, calendar, reminders, etc. (There's just somethng liberating about moving away from M$ Office products), but unfortunately I'm still stuck with M$ exchange... Should be no big deal with Apple's "exchange support" right? Wrong.


I have two exchange accounts on the same server, after setting them up (using auto-discover) on my Mac (10.8.2), Mac mail seemed to be working as advertised... I left mail open, grabbed dinner while my email sync-ed up... Came back and found that some of my folders were no longer there... so 2 questions for you all:


1. Has anyone had this issue with a previous version of OS X (10.8.1 or earlier) and found a solution? (or has apple provided them any direction)?

2. Has anyone had any luck with messing with the auto-discovery settings?


Any help would be greatly appreciated!

This is exactly the same behavior I have:


more than one Exchange Account with the same Exchange Server results into:


  • empty Mailboxes Folders
  • missing Folders
  • Resync of Mailboxes


I changed to only one (the main Exchange Account) and all others are now Imap4 (Calendar and Addressbook are still working with Exchange).


This works for me since 10.8.1 and still does with 10.8.2!


Still this needs to be fixed soon! I hope Apple will focus now back to Macos after all this IOS hype....

Sep 21, 2012 3:18 AM in response to opb1978

Yep, broken for me too.


iMac & MacBook Air all working fine under 10.8.1 and then for a while after upgrading 10.8.2, then they just stoped working.


I deleted my Exchange account from my iMac Mail and tried to re-add it and it will not auto-discover. I have now noticed that the same account that I left on my Air will connect intermittently, so I'm leaving that well alone.


This is a real pain as I use both machines to access my work email, contact & Calendars while at home.


Sorry this isn't a solution but Apple need to understand that Mail is a fundemental service and issues with Exchange Support are about serious as things get.

Sep 21, 2012 3:41 AM in response to sceptic

Hello, in my Option Apple is giftig us 4 choices:

1. accept the unabylity of Mail dev team and use the devices without busines services

2. Install a third party solution (Outlook for Mac or something else)

3. Give your macbooks or imacs as a gift for your children and use another well Wirkung alternative

4. Or start to bring more and more support request directly to the Apple Support team Witze weekly reminders


Now the first hype from iOS 6 and "Pokémon"-Services (facebook &amp; twitter integration........wow) on MacOS X is gone, i really hope they switch back to the needs now.
