Microsoft exchange email sync issues

https://www.apple.com/feedback/macosx.html

Hi. Thanks for the reply.

I have Mac Mail, Calendar, Notes, Reminders and Contacts running on three computers (MBP 15, MBA and 27" iMac) connected to the same Office 365 Exchange account.

There are various issues all of which seem to stem from a very slow refresh time between the Mail client and the Exchange server.

This manifests itself in a number of ways....

- Mac Apps crashing (primarily Calendar and Notes)

- Slow refresh time (minutes) for Mail on multiple devices (sometimes not appearing until I restart Mail)

- Mail messages moved into folders (I have 75 folders or so) reappearing in the inbox

- Deleted items reappearing in the inbox minutes after they have been deleted.

None of these problems occurred before I upgraded to Yosemite (except the app crashing, that happened periodically).

One point of note: Removing and re-initiating the Exchange link now gives me a message that Mail is running on the other machines (never did before). I presume they changed something in that relationship which, to me, would be a smoking gun....

Thoughts?

Not a criticism, but if it were me, I'd untag that "solved my question" answer because "use Microsoft Outlook" is not really an adequate answer for many of us.... It might be for me if Microsoft would only get off their tails and implement Favorites folders in O4M... /rant.

I had the same problem and tried quite a few things. Here is what eventually worked for me:

1. Delete the Exchange account in System Preferences>Internet Accounts.
2. Quit Mail.
3. Launch Mail and go to Preferences>Accounts.
4. Set up the Exchange account from within Mail, NOT from within System Preferences.
5. Once the account is set up, go to the Advanced tab inside the Mail account settings and uncheck 'Automatically detect and maintain settings.'

Setting the account up from within Mail got both Mail and Calendar up and running correctly but without unchecking that detect settings box, the account would lock up again the second time it tried to check for mail.

I had a similar problem and I did a variation of others' suggestion:

1. Deleted all instances of my Exchange account from Mail > Accounts and from Internet Preferences.

2. Rebooted the computer.

3. When to Internet Accounts in System Settings and added my Exchange account. However! The first time I was asked for a password, I entered a bunch of random characters that wasn't my password. When prompted that my account couldn't be validated, I clicked continue and on the second screen entered the proper password. I think this is a different way of bypassing the auto discover function.

This has worked for me.

Best of luck

Thank you, this worked for me. 😎

I have two exchange account. The one i use the most (20.000 e-mail) has the problem and the other one i rather use (1.000 e-mail) works fine. So it depends on the number of email you have in the server...

i have the issues. I think because both have several computer with the same account...

The way I got around this issue was by deleting the Exchange account, closing down mail, then adding the account again but using 'other...' as opposed to the 'Exchange' option. All the mail seems to be syncing normally now, there must be some sort of bug with the way Exchange account is being configured within Yosemite.

The 'other' seems to have helped as well. The only issue I've run into so far is that e-mail invites come-in as links, rather than 'Accept', 'Decline', or 'Maybe' buttons. Can't find anything online to help fix it.

I had the exact same problems. However reindexing the messages solved it for me.

Mail (Mavericks): Reindex messages

Work perfect!!!!!

I'm having the same issues. It takes 1-2 minutes longer to retrieve mail once the message has been sent. I know it's that long, because my iphone receives the email before my mac does... Have they found a solution yet?

Hello,

I have temporarily solution.

First of all, i have 3 Microsoft Exchange server. One mailbox server, one Cas server and one Hub Transport server. Mailbox and Cas servers version number is 14.3 and Hub Transport server 14.1.

EWS service was running on CAS server and yosemite mail app client cannot connect and cannot sync to exchange. But when i change client settings to other server (Hub Transport server version 14.1), everything ok.

Yes its not right solution but it's will save time for me.

And now, I'm investigating the differences between them.
