Why am I not receiving email from another O365 account? #M365AMA

In this episode, the #M365AMA panel discusses the following community question:

“I have an issue where my main email account (hello@example.com) is not receiving emails sent from another companies O365 email accounts (shop@client.com). I can see the email in mail trace and it says it arrived was delivered, but at no time did it appear in my inbox. I have no rules in place on the account and as far as I know this is the first time I have encountered this issue. I have several shared mailboxes (info/accounts/licensing@example.com) on my account and these receive the emails with no issues at all, so it’s just my primary business address. Just wondering if anyone has any ideas. I’m a mac user and I don’t use PowerShell yet so it would have to be done through the admin centre. “
