my emails will not sync on my Mac

Hello Evanthea,

For issues with emails being missing on the Mac, this page can help provide some suggestions that may be able to get things resolved: If emails appear to be missing in Mail on Mac - Apple Support

• If you use more than one email account in Mail, make sure you’re looking at messages for the correct account.

• If you sorted messages, they may be in the list but not in the order you expect.

• If the missing emails are from a specific person or group, check whether you blocked messages from them.

• If you use rules, they may have moved messages to other mailboxes. Try searching for the messages.

• Check the account’s Recovered Messages mailbox, if available in the Mail sidebar.

• Quit Mail, then reopen it.

If the problem persists, you may need to rebuild a mailbox.

If nothing on the above link was able to help, and the email account is provided by a job/business/etc, then you may also try reaching out to them for any specific guidance on setting up the Exchange account.

Cheers.
