Exchange under Mountain Lion

Gabarrios - others are less willing to do this, so it's up to you.

I disabled calendars, went to my Library, and deleted all of the files under calendar, emptied trash, and reset all of my calendars and allowed the library to rebuild.

You will have to rebuild all of your calendars, iCloud, Exchange, etc.

To get to the Library folder you go to the Go menu from your desktop and hold down the "option" button. The library folder will appear. Then go to Library/Calendars - and me personally - I deleted everything in there and then repopend Calendars. Your call.

I trued checking and unchecking Enable this Account and that didn't work. I'm a little hesitant to go into Library and begin deleting things (although I may have to). Also, Reminders isn't working but Contacts is. Very strange. I'll keep monitoring this thread for other ideas. If nothing comes up I may try deleting some of the folders.

delete under preferences exchange account

restart

delete under library/mail/v2/exchange folders. not mailboxes not maildata and not other like AosIMAP... (if you have other mailaccounts e.g. icloud ...

which folders under v2 for exchanges are you see the names and know how is your exchange. may be EWS-mailalias......

then create under proferences new exchange account. wait to sync complete 5 or 10 minutes

Calendar and Reminders are now working - just took a little more time.

So I have installed 10.8.1

Mail is coming in now... every now and then I get error messages like 'cannot move to trash' and 'unable to send message' indicating that the fix is not perfect.

Contacts seems to be working... every now and then I get an "!" icon and it alerts me "connection has been lost"

Calendar gets an "!" icon next to the Exchange folder and alerts me "your calendar couldn't be refreshed - the connection with server xxxx has been closed - please try again later."

So it's not perfect... unless I've done something wrong.

Mail "use Autodiscover" is unchecked.

Both internal and external are populated with mail.xxxx.com (the external server) on all 3 apps - Mail, Contacts, Calendar

Am I missing something?

I'm having the same intermittent issues (can't move some emails to trash, calendar cant get refreshed). I've noticed that whether I check or uncheck Autodiscover the behavior seems to be the same.

So it is better but not perfect. Also having to manually change server settings on all three apps separately is very un-Apple like (it just works?!)

I setup Exchange once, in Mail, all Apps (Contacts/Calendars etc) work fine. Your problems sound like a Lazy IT dept setup of your server.

Our IT department is in the process of migrating our Exchange servers from 2003 to 2010. I had been using IMAP integration to the Exchange 2003 server just fine. My mailbox was migrated to the Exchange 2010 cluster a little more than a month ago and I tried reconnecting Mail, Calendar, etc. using the new autodiscovery service and it worked like a charm...for about a week. Then Mail stopped getting new messages and I noticed the little warning icon next to the Exchange account. Ever since then I've been unable to receive mail from Exchange.

Interesting however is that Calendar, Reminders, and Notes all work perfectly fine. I applied 10.8.1 this morning and no change, however I see the ability to uncheck Autodiscovery but doing so still does not change my issue with Mail.app.

It would appear I spoke to soon. Everything worked fine on the corporate network. Everything worked fine on the Wi-Fi at a nearby Panera Bread. But when I got home Mail worked ... but as I noted much earlier in the thread ... Calendar and Contacts did not. These two apps just don't seem to use what's in the External Server field when I'm at home. And it seems to have been that way in Lion as well. In my previous post I mentioned how all the focus seems to be on Mail. Well I'm now even more convinced of that. I have Charter internet and an Airport Extreme base station along with an Airport Express as a network extender. I also use OpenDNS. So perhaps it's something about that setup that's causing this? In any event, I'm not inclined to spend a lot more time trying to figure out what's so different about my home network than Panera Bread's. If there are some networking gurus out there feel free to chime in. In any event, the good news is that I can simply uncheck the Use Autodiscover Service and put the entry that I would put in External Server into the Internal Server field and then don't use the External Server field at all. That's the way I had it setup in Lion. And Mail, Calendar, and Contacts are working at home again ... and I have no reason to think they won't all function properly at work tomorrow. Naturally, YMMV.

Hi All,

I just wanted to say thank you to the Apple Engineers, for bringing out a maintence update so quickly

I did the following

remove my exchange accounts ( i have 2)

Restarted

remoted the ~/library items such as the ews mail accounts, i remoted my addres book folder and also the ical in app support (only do this if you only have exchange accounts)

I then re added one of my exchange accounts in the system preferences, but did not tick everything

I have left the settings as there were, ie am using autodiscover

My email loaded, but i have to select each mail box and also rebuild each (tedious but worth it)

I then went back to check the contacts in the system prefferences

opened contacts

checked the settings, contacts appeared

did the same for ical

and also reminders

added my second exchange account

Things are looking ok, but just need time to rebuild

so thank you to Apple engineers, its looking good at this stage cross fingers

Hi All,

I think it is still not right, does seem to still be using the autodiscover setting for Calendar and Contacts. Contacts you can reset but Calendar goes nuts when you go for the account settings!

Agreed. The 'use autodiscover' button is checking itself back on automatically after a reboot or when opening Mail. Internally it works fine but externally there are still issues. I've tried different combinations like setting the external server name as internal, both - same results. It may work for a little while then it reverts the autodiscover setting to back on. Contacts and Calendar are not right either.

To All,

I want to say thanks to the Apple Egineers as well. I have installed the 10.8.1 patch and email, calendars and contacts are all working again with my hosted Echange account. I am checking on the battery but it looks like my battery life is also back to what it was before the upgrade.

Yep I spoke too soon.

The account reverts back to autodiscover settings. Arrrggggggggggggh.

You can't even access your Exchange Calendar account at all - you have to force quit out of Calendar if you try.

Super no bueno.

Back to the hosts file fix.

After trying out a few things, the hosts file is the only thing that is still working.

Back to the drawing board Apple.
