Looking for some best practices, 

 

1. Is there any way to set up Microsoft Team "Channel" email addresses to use *@contoso.com instead of 6f37b12d.contoso.com@amer.teams.ms.

 

 

2. We are experiencing ALOT of emails getting caught as phishing (AntiPhishPolicy) or SPAM from the @amer.teams.ms  and  noreply@email.teams.microsoft.com  sender addresses for some reason in EOP/EOL and security is not wanting to whitelist those domains.  

 

 

Any suggestions or either or both Team? Thanks for your time.

No. As explained in the documentation/blog articles, Teams uses a special tenant for handling the email to channel functionality, and we have no control over it. You can however create a mail contact for the generated address and assign it a user@contoso.com alias.
