Exchange in Mail.app

Same problem. Apple?

Ugg the mavericks mail update did not fix this for me... 😟 I can verify like others on this thread if I can get to the internal server (corporate network) it works fine. If I have to go through the OWA server externally then messages are very delayed getting to me and some times just stop for awhile and no attachment over 200K can be sent.

I have the same problem with mail.app and an exchange server. The update of mail.app today has not changed anything.

If I send a mail with an attachment mail.app will not able to send this mail via exchange.

Bump, same here.

Bump... still ongoing. This is a HUGE bug for those that use OSX for a work computer. !!! Even a work around would be better than nothing.

I am having troubles with OSX 10.9 Mavericks Apple Mail and MS Exchange, too. I used the Migration Assistant to pull my user account from a Time Machine Backup of a Snow Leopard system (OSX 10.6.8).

My troubles are with email RETRIEVAL DELAY. I can send email with no troubles.

I have tried REBUILD of the mailbox.

I have tried deleting the Apple Mail Account that points to the Exchange Server.

I have tried closing Mail, then moving ~/Library/Containers/com.apple.mail/Data/Library/Preferences/com.apple.mail.pli st to the Desktop, and then re-opening Mail to rebuild the com.apple.mail.plist preferences file.

I have gone into the Preferences->General and changed from Automatic to Every 1 Minute ... email retrieval is like waiting for a log jam to break free. Retrieval delay varies anywhere from a couple of minutes to a couple of hours.

I can hit the "Get new messages" button all day long and nothing happens.

My iPhone 5 (iOS 7) is pointed to the exact same MS Exchange account and it picks up emails from the server way faster than Apple Mail on Mavericks. I had no problem with Apple Mail on Snow Leopard.

I noticed that Apple Mail was updated on Nov 8, 2013, but no mention of MS Exchange enhancements or known issues list.

Same attachment problem here. Also having the delay in receiving messages. Help Apple!

I am experiencing similar delays with retrieving mail from Exchange 2010.

Sometimes restarting Mail.app helps and new email shows up. It will sometimes even stay in sync for a short period of time. The recent update does not seem to help.

Mail.app - Version 7.0 (1822)

Back to the top...

Help apple !!!

I found a solution for fix the mail.app problem on my Mac. I have to switch off the Exchange autodiscover service (Preferences -> Accounts -> unmark the autodiscover service) and enter the correct (internal) server adress. Now, I can send mails with large attachments without any problems.

Hopefully, this workaround fixes my problem.

I and another collegue in my office are also having the exact issue you initially described.

I have reported it as a bug with Apple and referenced this discussion.

I am running "Exchange 2010 SP2 Rollup 4 version 14.02.0318.001" and Mail.app Version 7.0 (1822).

Bump.. still broke.. removing the autodiscovery doesn't work externally..

After waiting for more than a month, my solution is to install the commercial mail plug-in Lokiware: Attachment Tamer for Mac. Right now running the pre-release version for mavericks.

It is an understatement that I hate to use a commecrical software to fix the flaws in another commercial software, but I guess that is life nowadays.

It is strange why apple software engineers don't fix this problem. It is clearly fixable.

All problems are solved for me now, and got some bonus features like the removal of bogus “ATT0001” attachments.

It will be ironic if this post will be removed as unpermitted advertisiment of third party software.

Have the same Mail/Exchange attachment issues as everyone else here.

I've been using Attachment Tamer for a long time now, great plug-in. It does however not solve the problem for me.

First Gmail and now this... they really should take a better look at Mail.app before they launch an OS update.

I wonder if Mail in iOS has the same issues?

You are right. I did not solve the problem. It worked for a few hours however, and it still works intermittently. It is a change that I don't have to try resending all emails several times.
