Exchange under Mountain Lion

I also experienced Apple Mail functionality restored to normal after removing MailTags and MailActOn.

Thankfully I didn't have to go without either of these useful tools for long as the problem did not return when I reactivated them.

I'm keeping half an eye on the developer's website for related discussion.

Hi Turgi,

I have similar issues with addressbook (https://discussions.apple.com/thread/5252673?answerId=23340805022#23340805022&ac_cid=op123456#23340805)

were you able to solve this problem?

I had those installed a good 10 system reinstalls ago. Took them out long ago with the perscribed manner for each. What was odd was that in one of my trace logs, it looked like MailTags was still around some how even though I can find no trace of it. This was 5 system reinstalls ago, maybe in March.

I know (hope?) MailTags is uninstalled via the absence of:

~/Library/LaunchAgents/ca.indev.MailTagsHelper.agent.plist

~/Library/Mail/Bundles/MailTags.mailbundle

and MailActOn is similarly uninstalled by the absence of:

~/Library/Mail/Bundles/MailActOn.mailbundle

and in fact, I deleted the entire "Bundles" folder long long ago. Still the henious Mail, Calendar problems under Lion and Mt. Lion persisted. Most of what I have seen are Apple software defects (guarenteed). Under Lion and Mt. Lion I gave up trying to use the native MS Exchange compatiblity and starting running DavMail on my Mac as a proxy converter. DavMail has enormously better compatilbity with MS Exchange than the aforementioned AppleMail products al though DavMail is slower than molassas in January Java, it goes where no code has gone before.

After 1 month Mail App stopped syncing my inbox again. Interestingly enough subfolders were synced but not my inbox and I could not send mails any longer.

No clue what triggered its sudden death. Reinstalling the account did not help. When I created a new user under ML and installed the same mail account with identical settings again, it did work. However still not on the existing user account.

Going back to previous pactches i used for the existing account, I retried this one:

1. first go to Mac Mail Preferences

2. Under Accounts, go to Advanced tab.

3. then from the drop menu "under keep copies of messages for offline viewing"

4. Select: "Don't keep copies of any messages" when the warning message pop-up click ok

5. after you save, close Mail and then re-open it, then the emails you've been trying to delete/move and etc... it will be flushed and the email will start sync normally.

6. remember to go back and put the settings as it was before, then close Mail and re-open.

And yes i revived my maibox again.....for as long as it takes.

Maybe someone can figure out why this works (temporarily).

Menawhile i hope for significant improvements under Mavericks or otherwise i change to outlook i guess.

I have been watching this discussion since the beginning and I experienced similar problems with Apple's mail client after I recently upgraded to Mountian Lion (I had cancelled an earlier upgrade because of other problems). Mostly, I noticed that some folders have been disappearing (fortunately, in the client views only - not in the Exchange mailboxes themselves). So, I switched to DAVMAIL, which seems to work fine so far and I agree so much with someone who recently wrote in here that Apple should hire these folks in Cuppertino as soon as possible and let them take over the mail client development. To be honest, upgrading the mail client had a good side, too: being a Greek citizen and living in Athens, I had trouble using Greek character sets and encodings in older versions of Mac OS X, which went away in version 10.8. Mail not working is clearly a frustrating experience - other than that, however, Mountain Lion (and Macs in general) is an awesome offering.

Installed Mavericks today. So far Mail has behaved itself and my Exchange account continues to work without problems...

Mail Version 7.0 (1816) (was 6.6 under ML)

same here...

in ML it did not work, Mavericks seams to finaly fix the problem!

2 years waiting to get a working mail....

2 years?

I didn't have any problems with Lion and Mountain Lion exists for one year!

But it was long enough also for me.

Hi everybody,

updated to Mavericks on Sunday. No problems with exchange. Everything is doing like it should.

Installed ML in July 2012, "upgraded" back to Lion, now Mavericks seems fine again.

Greetings from Bavaria

Problems are back

Indeed it even get worse!!! is this why we get it for free 😟

thinking about get back to windows

icloud and 2 exhange account mixing everything together

notes not syning, after sync 2 calendars 1 gets disabled automatic grrrrrrrr

pfffffff

I too spoke too soon.

Seem to be having some problems sending some Exchange emails with attachments. They send OK when I switch to my me.com account.

A new problem under Maverick using hosted Exchange: After selecting any mail in the overview of the selected folder, the mail content preview window (the right window) flicker after approx one minute and then mail suddenly shows the receiver of mails in the headlines instead of the sender (this happens in the overview window in the middle, next to the folders window). I also tried to reinstall the account and building the mail database again after upgrade to Maverick, but the problem is still there.

When does this continous chain of problems with Exchange stop?

Thanks! It worked for me in Mavericks, even with the VPN (Cisco IPSEC) connected.

Still having insane processor use / hogging and hence battery drain in/from Mail when connected to the corporarte network and Mail is able to reach MS Exchange.

A moment ago the Mail activity monitor showed no threads active and processing yet Mail was using beyond 150% processor. It started almost immedaitely after I connected to the corporate network via VPN (Cisco flavor) and Mail could reach exchange. It continued for quite a while (say 30 min or more) and then mysteriously settled down.

Mail is still the largest processor pig on my system, whether idling and using 10-20% (100 times more than most) or doing anything and chewing up sometimes beyond 200% (aka more than two processors). Pixelmator, Adobe products and even MS Office with it's nortoriously bad engineering design does not do this.

And, to top it off, it still refuses to quit much of the time.

BUT, as odd as it seams, it is much better in Mavericks than prior. There is progress and for that I am thankful.
