Exchange under Mountain Lion

The problem in Lion is the disappearing folders, if you have two or more Exchange accounts on the same server, you will start losing folders and/or email. So if they fix the ML issue, I have a workaround for the Lion issue. It's just the ML issue has made the Lion issue happen again, so without a fix for one, I can't workaround the other. Soon, hopefully soon...

Adding a host file entry to have my mail client remap to the external address 100% of the time worked like a champ for me. It looks like the issue is the client not switching addresses as it should. Basically the mail client wants to use the internal address all the time and not fail over to the external address, even when the internal one is unreachable. To me, that's what the reall issue is.

This might not work for someone in an organization that doesn't allow connectivity o their external server from within their own network.

I finally gave in and edited my hosts file as you suggested. It works.

Thanks a ton. I think you've figured out the issue.

I'm on the road at the moment and this gives me full access to my account.

(Here's hoping that Apple will come out with a for-real fix, but in the meantime this gets me working without having to depend on Outlook 2011 and having to manage two calendar apps.)

I should probably mention that our office has a single server - no load balancing to worry about. And that because I'm on the road, I edited my hosts file and pointed the .local server that Mail seems to insist on using at the IP address of our external server.

This works well on the road. I'm not in the office and can't tell if it will work on the LAN or not.

Dear All,

after reading this thread very carefully and trying some of the advices (changing hosts file etc.) with limited success I found a solution that worked for me:

Deleting the exchange account in mail, calender and contacts. Reboot. Setting up the new account in mail, calender and contacts. Manually type in the external and internal server (need to point ssl) and instead of EWS I´´m using /ews.

Thats all.

Till now, meaning since 2 days, it seem to work

Kind regards

Norbert

Could anyone help me to roll back to Lion from ML. ? Trying further without an apple fix this is becoming more frustration for me. I have no time to try anything further. Apple this time has gone wrong and should admit this. We should demand this to be solved with a fix ASAP!!!!!!!!!😠

It is my understanding that you just reinstall Lion over ML and you are back. Download Lion from the App Store if it was purchased from there. It sounds too easy to be true but that is what support told me when I called them about this Exchange issue. I ask them how to rollback to Lion and that was their answer.

Good luck.

You can't download Lion from the App Store anymore, the links are no longer there and they were replaced with Mountain Lion. If a person wants to roll back to Lion they will need to do a Recovery Install from the recovery partition or USB stick.

Thanks for the suggestions, but this did not work for me. Works for a few minutes, then dies. If I rebuild the mailbox it again works for a while. When I click on the mailbox I see no messages. Once it fails I can not send or retrieve any new mail.

I hope that there is a fix out for this soon.

Good luck everyone

When is the last time somebody got contact from Apple? It has been a couble of time now and there is no update yet.

@Apple: please let us know what the status is. On which date can we expect an update?

Yesterday I got a 2nd call back. They are aware of the issues and monitoring these threads. They are working on a solution at least for the Mountain Lion issue. The original Lion issue is still in progress but no word as to when a fix will be out. Pretty much it was just a call to say Please Wait.

At least a reaction - and if they don't delete your post I'll try to be patient and stil hope that there will be a fix soon.

Same issues here as most folks reporting. One of the universities for whom I teach was running a 2007 Exchange server, and I had nothing but trouble trying to set my Mail up (New MBP I bought in July). Could never get it to synch, or send mail in a reliable manner. I could get it to connect the first time and diplay an inbox, but that was about it.

Last weekend the university migrated to a 2010 Exchange server, and I was expecting more headaches. Fortunately, the IT guy called me yesterday and we went through the account set up and everything seems fine so far.

Now if I can just get my full-time university that uses First Class to connect . . . .

On another note, the recovery partition on Mountain Lion isn't working for me.. https://discussions.apple.com/thread/4182932?tstart=0

So I have that problem and the Exchange problem.

It's almost as if I'm using Windows.

(Sorry for the pointless post)

Sorry I believed the Apple rep when he told me that I could download Lion from the App store since I purchased it from there 😠. I just launched the store and selected it from the list and it says you can't install that version of software because mine is already newer.

Sorry for the bad advice even if it did come from Apple support.
