Q: Not all messages being synced in Mail

Hi all,

 

My Apple Mail is exhibiting some strange behaviour and I haven't been able to get to the bottom of it, I was hoping someone here might have an idea.

 

In Mail when I open a mail folder and read the message count at the top of the window it suggests there are 8500 messages in the folder, but when I open the same folder using Outlook on PC or Mac or in the web access client there are 8524 messages in the folder.

When I right-click the mail folder and select Get Account Info, it suggests that there are 8524 messages on the server:

I can't figure out why it won't sync the other 24 messages.

This seems to be the case with most of my folders where some messages are missing, for example I have an archive folder where Mail syncs 136 items but in all other clients and on the Get Account Info window it reports as 139 another example where a larger number won't sync is one with 2090 in Mail but 2344 in all other locations.

 

I have tried a number of things including reindexing mailboxes, setting up the account from scratch and disabling conversation view to name a few.

 

I should mention that this is connecting to an Exchange 2012 server using Exchange and Apple Mail 8.2 on OS X 10.10.2.

 

Any advice or insight would be appreciated.

iMac, OS X Yosemite (10.10.2)

    Hey there William-au,

     

    It sounds like your Mac Mail application isn't updating with all the messages you have in your Exchange server. The fact that it is getting information tells me your settings are correct and you have done the troubleshooting for it I would have as well. I found this bit of info from the following article that might help the situation here:

     

    OS X Mail: Using Microsoft Exchange (EWS) accounts

    ...This may happen if certificate authentication is enabled on the server and your mailboxes have a large number of email messages. Microsoft recommends that you keep fewer than 5000 mail messages in Exchange mailboxes.

     

    Thank you for using Apple Support Communities.

    Regards,

    Sterling

    Hi Sterling,

     

    Thanks for taking a look, I did see that KB article but I am not using certificate authentication and this is occurring on mailboxes that even have as few as 100 or so messages. I was trying to think about whether or not Mail might be automatically ignoring duplicates but I am not sure. Any thoughts would be appreciated.

     

    Still quite stumped though and on further investigation it doesn't appear to be only me affected, it appears that everyone in my company is having similar issues.

     

    Regards,

    William
