I'm working on a request from a customer who needs to redirect all external emails sent to a specific user's inbox to another user's inbox. However, they want to ensure that internal emails continue to flow to that original user as usual. The reason for this is due to the user's health issues. They want to maintain access to internal communications but completely avoid seeing any external emails. Changing the email address of the user isn't an option, as this user has been part of the company for decades and receives hundreds of emails daily. I initially thought about using a transport rule in the Exchange Admin Center, but I'm wondering if there's a better solution out there. They have tried setting up Outlook rules, but some external emails still managed to sneak through, so it needs to be foolproof.

To get this done, you'll need to set it up through the Exchange Admin Center. Look for mail flow rules to create a transport rule that redirects external emails intended for that user.
You can create a transport rule that specifies any email from external sources to be redirected to the other user. Just make sure you've set the conditions correctly to catch all external emails; it can get tricky, but it's doable! Also, it might be wise to chat with HR or Legal about this setup since the situation seems a bit sensitive.
Thanks for confirming the transport rule! I know HR and Legal are aware of the request, but it still feels a bit odd. I’ll keep records just in case!

Exactly! Transport rules are definitely the way to go. It's the most reliable method in this case.
