Apple’s Yosemite Doesn’t Work With Exchange On Multiple Macs

Apple’s Yosemite Doesn’t Work With Exchange On Multiple Macs

And Apple’s technical support doesn’t know why.

I’ve been a Mac since Oct. 11, 2007. In that time, I’ve made a lot of pronouncements about how well Macs work. But today, Nov. 6, 2014, I am ANGRY to report that Apple has completely screwed the pooch when it comes to Exchange working in Mac Mail on multiple Macs. It flat does not work.


When one creates an Exchange account on one Mac, say an iMac, and does it in Mac Mail, it works fine.

When one opens their Mail client on a second machine, say a MacBook Pro or a MacBook Air, a dialogue message pops up saying the password, which was entered correctly on the first machine, is wrong. What is wrong, instead, is that in the Username fields on the second and third machines, the @domain.com portion doesn’t come across so the two machines perpetually are looking for just the user name on the account, not the entire username@domain.com.  Screen Shot 2014-11-06 at 6.48.17 AM

As long one doesn’t try to use Exchange on multiple machines, which is the very idea and premise for it, it works on the one machine.


The guys at Apple Care have spent more than an hour with me noting this issue. They say that it can’t be something wrong with Internet Accounts, that it has to be an Exchange issue, which of course, since it’s a Microsuck creation, they don’t support. But it’s their system of Internet Accounts that precludes one from being able to set the email account up on the three machines without it being stuck in the Cloud portion of the OS, therefore making this an Apple issue, not an Exchange issue. Screen Shot 2014-11-06 at 6.49.55 AM


The two machines that it’s not working correctly on both had Yosemite Beta on them. I did a reload of Yosemite on the MacBook Pro last night and tried it fresh this morning.  It’s not a Yosemite Beta issue, and not one that was remedied when Apple issued Beta Seed 1 on Tuesday night, either.

I’m about to call my Exchange provider and switch the account back to a simple IMAP account. Apple is apparently unable to handle an Exchange account on multiple machines in Yosemite.

If you have Exchange and are considering upgrading to Yosemite from Mavericks and you run the same account on multiple machines, I suggest you wait till Apple gets it’s stuff together and hopefully fixes this dramatic business interruption.

BTW, Exchange is working on the iPhone and iPad along with the iMac. But when it gets to the other two Macs, forget it.
