Hi @Glenn Maxwell ,
Welcome to our forum!
couple of users have reported issue that they are unable to see emails in legacy outlook for MAC
What do you mean about "unable to see emails"? Empty mailbox in Legacy Outlook for Mac? Or maybe you can't get real-time update emails? Please provide more information about your case.
In addition, in order to further confirm the issue, it's suggested that you could try to remove the account configured in Legacy Outlook and re-add it to check if there're any differences.
