Hello Leigh,
Welcome to the Microsoft Community! I understand how frustrating it can be to deal with missing emails, but I’m here to help you get this sorted out.
I suggest to Logging In via Web Browser, Log into Outlook Web App to see if your emails appear there. This helps determine if the issue is device specific.

If you're able to log in to Outlook on the web but still can't find your emails, no worries just follow the steps below to help troubleshoot the issue:
Sync Issues on Devices sometimes, sync issues can cause emails to disappear:
On your Mac: Open Outlook then select Preferences select Accounts then select your account Click “Advanced” then hit the Check sync settings.
On your iPhone: Go to Settings then select Mail then select Accounts then Select your account then select Toggle Mail off and on.

Recover Deleted Emails If emails were accidentally deleted:
Go to Deleted Items folder
Scroll to the bottom and click “Recover items recently removed from this folder”.
If none of these steps work, it would be helpful if you could share any error messages or a screenshot that way, we can better identify what's going on. And if you have any questions, feel free to reply to this thread. I'm here to help.
Kind Regards,
John Oli
