Exchange under Mountain Lion

i have just taken up the option to use Outlook 2011 free for 30 days and all the problems I had with Apple Mail since the ML upgrade are resolved. If Apple have not fixed within 30 days then I will be converting over to Outlook for good.

My issue with Apple Mail using exchange was that the download of messages would start each time I created a new exchange account but would only update some folders then pop up asking me for my password (nothing would happen when re-entering password

Tried all the tweaks discussed in this forum and nothing worked

Again, Apple, you have 30 days to fix and by the way Outlook appears to contain many more integrated features. With apple you have to open a seperate app for Calendar, reminder, mail and contacts. Microsoft is all in one app. This is basic stuff...

A lot of posts are referring to Apple Mail. Isn't it affecting both Apple Mail and MS Outlook 2011?

Hi leechicago,

the issues exists only for Apple Mail. MS Outlook 2011 is working as expected.

I have the same issue.

The problem is only in the Mac Mail 6.0 and Calendar, Contacts e etc.

Outlook 2011 works regular with Exchange and Mountain Lion.

Apple, please, fix this problem.

Thanks

Everyone: This topic is being monitored by Apple, I suspect many of you like me were contacted by them for log files.

Mine is working, not sure if this duplicates other responses, but here are the facts on my end:

We use Exchange 2007. The box it is running on is "nameofserver.internaldomain.com" inside the network, the outside DNS entry is "mail.externaldomainname.com" (note, the external domain and internal domain are not the same). We have a single SSL cert (through GoDaddy) that is the certificate for nameofserver.internaldomain.com but it also aliases mail.externaldomainname.com.

In Mail preferences I placed "mail.externaldomainname.com" in *both* the internal and external server entries under the advanced tab, and I made sure that SSL was checked for both internal and external. If you exit and go back in, the ML Mail App does change the "internal server" name to "internaldomain" - NOTE - it did not change it to "nameofserver.internaldomain.com"

However, mine has worked ever since, no issues.

I have installed ML on three computers and they all have the same problem. I have multiple exchange accounts in my Mail client but on different domains and besides they arent working as most of us have experienced they all are losing folders in the client. Sometimes they are there, but next time you start most of them are gone. Everything is working on the iPads and iPhones. No efforts that i have read here has done the trick. None of these problems occured in Lion.

We only have external exchange servers but have to rely on our iPads. We are dealing with patients emailing us every day with healthcare problems. For us its really serious if our mail doesnt work. Thankfully not all computers were "upgraded" with ML so some doctors still run LIon. Please help fast, this can be hazardous for our patients.

TIA

Can everyone check and confirm something for me. Go into ~/Library/Preferences/ do you see a file called com.apple.mail.plist? After firing up Mail the first time on each account on my macBook I find that this file gets deleted.

No. I only have a file named. com.apple.mail.plist.lockfile

THANKS MICRO67, I've tested it on 3 accounts. Appears Mountain Lion removes that preference file as soon as it runs the first time. Not sure if this is related as this was not the behaviour of Lion or previous OS versions.

Checked my other computers with the same result.

It removes the file the second you start Mail for the first time.

Thanks. I just wanted to make sure it wasn't just my computers. And that may be normal for 10.8 but I wanted to confirm.

I think that that summarizes our situation too. Our Exchange implementation involves several individually named machines (xxx1.xxxxxx.xx, xxx2.xxxxxx.xx, xxx3.xxxxxx.xx etc.) but as I understand it, for load-balancing purposes the server address (internal and external) is simply xxx.xxxxxx.xx. Very occasionally under Lion (once or twice a month), but now almost hourly under Mountain Lion, the internal server name in Mail will switch from xxx.xxxxxx.xx to one or another of the individual machine's names (e.g., xxx2.xxxxxx.xx). As far as I can tell, because of the way that Mail stores its offline copies of mail (in the Library/Mail/V2/"servername"/Inbox.mbox, etc.), as soon as the server name is switched, one loses access to all the downloaded mail under the other server directory. Rebuilding the mailbox downloads a new copy but it's a real pain. I hope this is fixed soon.

I had the same problem at the office where my internal exchange server address kept reverting to a local address that prevented any sync of emails, calendars and contacts.

I used the etc/hosts trick described earlier and it worked perfectly. The calendars were synced again and I could even find shared calendars accross my firm.

I think the issue comes from the autodiscovery function of MS exchange.

Somehow Apple needs to allow Mail users to disable it and everything will be fine.

I'm still in disbelief that Apple relased Mountain Lion without this issue sorted out. What a sloppy job !

Steve would never have let this fly !

You hit it when you say its the auto discovery of the address causing the issue. It appears in my situation that the auto discovery domain name is different than the address for external connection.

Something for everyone to check.

Ping the address that it auto discovers and then ping the address you were using before and compare. My case the IP's were different. I added a entry in etc/host file that changed the IP of the auto discover to the actual IP and Mail and calendars are working fine now and has been for a couple of days.

It is advisable that people who use the Exchange did not upgrade yet for the Moutain Lion. This problem is giving a lot of headaches.
