I have a 365 client that is trying to E-mail to known good address but gets a bounce back that the address can't be found. I can E-mail the same address from any other source and it goes through. But from the 365 users, it won't go. Below is the bounce we are receiving.
I'd like to call 365 support but can't find a number. Does anyone have the number?

This error occurs because the sender sent a message to an email address hosted by Office 365 but the address is incorrect or doesn't exist at the destination domain. The error is reported by the recipient domain's email server, but most often it must be fixed by the person who sent the message. If the steps in the How to Fix It section above don't fix the problem, and you're the email admin for the recipient, try one or more of the following:
The email address exists and is correct - Confirm that the recipient address exists, is correct, and is accepting messages.
Synchronize your directories - If you have a hybrid environment and are using directory synchronization make sure the recipient's email address is synced correctly in both Office 365 and in your on-premises directory.
Errant forwarding rule - Check for forwarding rules that aren't behaving as expected. Forwarding can be set up by an admin via mail flow rules or mailbox forwarding address settings, or by the recipient via the Inbox Rules feature.
Recipient has a valid license - Make sure the recipient has an Office 365 license assigned to them. The recipient's email admin can use the Office 365 admin center to assign a license (Users > Active Users > select the recipient > Assigned License > Edit).
Mail flow settings and MX records are not correct - Misconfigured mail flow or MX record settings can cause this error. Check your Office 365 mail flow settings to make sure your domain and any mail flow connectors are set up correctly. Also, work with your domain registrar to make sure the MX records for your domain are configured correctly.

@Brian Reichert Similar issue with one of our shared mailboxes. But there are no emails delivered from any domain. Did you ever figure out a solution? -O'Fetfa
