Apple Mail Not downloading Emails in Exchange

The only thing that "works" for me is to rebuild the Inbox folder. I then get all my emails from that moment and earlier.....but still no future emails unless I rebuild again. Rebuilding is crazy though.

Hello laynestaley123,

Thank you for using Apple Support Communities!

Based on what you mentioned, you are having some trouble with how Microsoft Exchange is being sent or received. The Mail app is more of a conduit for how your actual account is configured. If you are not receiving emails to Mail, it may not be configured according to what's on the main server. To make sure you get all the necessary configurations, you may need to reach out to Microsoft's support. However, there are a few links that may help listed below.

• If you can’t receive emails in Mail on Mac.
• Microsoft Exchange features in Apple devices.
• Microsoft Exchange integration requirements for Apple devices.
• Payload best practices for Apple devices.

Best wishes!

This has been doing this for a week on all 3 of my Apple computers. I am really upset about this since I use them for work and I have to rely on Outlook to see what emails I am missing. It sometimes comes back to life, like all day this Sunday (Dec 13) and then it died again yesterday early morning. I contacted Apple support and they were useless, and contacted Microsoft which was just as useless. Both point the blame to each other. My iPhone and iPad Apple mail works perfectly with Exchange, so why not on MacOS???

I've been experiencing the same exact problem, intermittently, for the past week or two. FYI, I'm running macOS High Sierra 10.13.6 on my MacBook Pro. This has made Mail on my Mac virtually useless, as I can't trust it to display the latest mail in my Inbox. Therefore, I've moved to Outlook for the time being (as many other people have done), as it reliably talks to the Exchange server and displays my latest incoming messages. I've used Mail on my Mac for years and years, and this is a major inconvenience, so I'll be watching this forum for any breakthrough solutions.

For an update, one of my three computers has finally come back to life when it comes to Apple mail with exchange. It’s the fastest one of the three, so I don’t know if that has it anything to do with it. It is not showing me mail instantaneously but it pretty much updates itself every few minutes, even though I have it set to automatically send and show up immediately. Somebody at Microsoft reached out to me via email and asked me what was going on and if it was happening still, and I told him it was. I did tell him that one computer seems to be working more or less. Still isn’t right. I am loading the new beta for Big Sur tonight on one of the ones that is not working to see if that does anything.
