Exchange under Mountain Lion

D43m0ms - do you have mutiple exchange accounts setup in Mail? If so, are the accounts for the same domain?

D43m0ns,

Did you have multiple EWS folders? I did. In fact, I had one for each different time I re-added the account using a modified version of the credentials. The only other thing I could suggest, other than a patch from Apple, is to make sure that you deleted all of them.

No, just one Exchange account

No, I just have one EWS folder. Also after quitting Mail, moving the EWS folder out of place and starting Mail again, I still had one EWS folder. That didn't sync at all, so I quit Mail, deleted the newly created EWS folder, moved the original EWS folder back in place, started Mail and had to rebuild each folder in my Exchange account in order to see the messages again.

It's Apples turn to make a move, if not I may have made my last towards them... (sad but true...)

A week later, my settings have not changed, My internal and external server are the same listed as "owa.your corp.org". Mail is geting updated on Outlook, no messages are lost, the same info is across my iPad, iPhone and Mac 17" early 2008. I have been using my Calendar and it stays updated in Outlook and iCloud.

My corporation uses Outlook 2007. I guess IT has configured Outlook correctly to play with Mountain Lion.

An update to Mountain Lion is on the way

Here's hoping...

Really odd but I managed to get Mountain Lion re-installed today and my Exchange email is working. However, I thought I'd remove my iCloud .me mail from Mac Mail and use Sparrow for the .me account. As soon as I removed the iCloud account from preferences, the Mac Mail Exchange account stopped working. I put it back again and my Exchange email started to flood in..

No idea why this might be the case but thought I'd mention it.

Edit to say: and now it's gone again. It's impaortant to state that when I reinstalled Mountain Lion mail worked, even after a few reboots. Now I've gone and stopped it working again 😟

So here's some more info to go with yours....

I turned off iCloud and left my two exchange accounts active. I set the internal server to mail.company.com. If I close and reopen Mail.app the setting retains mail.company.com. If I go into settings > accounts, as soon as I attempt to close it I get prompted to Save Settings. If I say no to saving settings, the internal server changes to ex1.company.com. If I answer yes to saving settings, the setting stays as mail.company.com. Next, I turned my iCloud accont back on and now going into settings I never get prompted, it just automatically changes the internal server of the exchange accounts to ex1.company.com.

It appears that having the iCloud account turned on causes the settings to update and self-save.

And the cherry on the cake:

"the Mac maker asked developers to focus their testing efforts around USB, PAC proxies in Safari, Active Directory and Microsoft Exchange support in Mail."

Finally Apple!!!!! Better late than never....

Question is - does anyone here have access to try out this developer build? Asked that previously on this thread and didnt get a reply - so I'm guessing not 😟

And spent an hour at the Genius Bar today trying to get downgraded to Lion. Unfortunately seemingly not possible as my MBP shipped with Mountain Lion - to be fair to the guy, he seemed to try pretty much everything!

What you're asking can't be discussed publicly, due to NDA restrictions for those who have the Apple dev licenses.

I was fortunately able to reinstall & downgrade to Snow Leopard losing some files & apps in the process but Lion & Mountain Lion don't cut it.Apple have effectively 'dumbed down' their Software upgrade to 'marry up' with Pad & Phone as opposed to upgrading those to match Mountain Lion.Simply,Snow Leopard is a better app.The supposed advantages of the Lions are easily added to the OSX of Snow Leopard.My advice is downgrade & add cherry pick the favourable advantages from the other OS.

Is is easy do downgrade using time machine copy? Is there any other way to reinstall Lion? Apple should at least provide support to us to be able to downgrade back to Lion. I do not want the cost to be paid back to me for purchse of ML. They can use this money to set up foundation to investigate exchnage issue with ML.!!!

Don't have too much hope. Apple Engineering got back and told me that the fix needs to be on the server side from my company and this is a solid information they have for now. Also, they forwarded me the latest article from Apple that talks about the same. However, until the fix from my IT guy is issued, the temporary fix is what BiffqrgRwrzhwrerz mentioned earlier (Page 21). This will disable the Autodiscover for 100 days.

They never acknowledged that it will be fixed or is their problem. Instead suggested that my IT guys needs to work on a fix.

I tried the aforementioned auto discovery fix and its working fine as of now. Here is what you need to do:

- If you have Exchange mail already added, remove it and remove all Exchange remnants from Keychain as well.

- Close Mail

- Reopen Mail and add the exchange server and save the settings. Make sure its pulling in all the mails

- Go to terminal and run the command as mentioned by BiffqrgRwrzhwrerz or as below

defaults write com.apple.mail ReautodiscoveryTimerInterval 864000

- Close Mail completely. Wait for 10-15 mins and reopen to see if you still have problem and then report back. I had to try different things for 30 mins before the above solution worked.

Hope this helps for now and hope that 10.8.1 fixes this issue with Mail.

Greetings,

Exchange 2007, and 2010, works well with ML - we have no issues that we haven't been able to fix, after callung Microsoft.

Microsoft didn't get fix out to the Exchange users in time, nor was Apple provided with all the Exchange details it needed, before publication. MS is always a bit slow to get things done.

Your IT folks need to call MS, not Apple, to get a fix. We did nothing to 2007, except a configuration change to the Exchange Server, and we worked with Microsoft Engineers to get it all working.

Unfortunately, people have the tendency to blame Apple for any third party issues where their program doesn't work. It has never been Apple's responsibility to make other peoples software work. If they get the proper info to Apple, in time, they will include it in the update/software. Everyone has ample time to get their software updated before a new OS X version comes out, and get the proper information to Apple. They should have an update ready for direct updates, if they don't care to have Apple do it, and there are some that are like that.

As I've said, we have no issues, currently, for a few hundred users.

Cheers,

M.
