Email address policy

Question

So in our environment (Exchange 2016) (Hybrid) we have multiple accepted domains like below:

1. XYZ.com (Authoritative)
2. ABC.com (Authoritative)
3. XYZcorporation.mail.onmicrosoft.com (Authoritative)

XYZ.com is the default domain and majority of our users will have their emails as alias@xyz .com

We have an email policy called "Policy1" which is the default policy. Following are the setting for the Policy1:

General:
-Policy name: Policy1
*Run this policy in the sequence with other policies:
Lowest

-*Email address format:

SMTP @xyz .com

smtp ******@XYZCorporation.mail.onmicrosoft.com

X400 c=US;a= ;p=XYZ Corporation;o=xyzNet;

-Apply to
*specify the types of recipients this email address policy will apply to.
-All Recipient types.

Issue: default policy is applied to all of the users in XYX.com domain and for users/mailboxes in ABC.com domain the " Automatically update email addresses based on the email address policy ...." is not checked or enabled and this is by design.

So, I want to now create a new email address policy and apply it a mail enabled security group to have the missing " smtp: ******@XYZCorporation.mail.onmicrosoft.com" and keep their SMTP of ABC.com to remain the same.

So, how would i go about achieving this?

Hi @Safs-3080

Please note that according to the official document: You can't filter recipients by type or properties (applies to all recipient types).

The supported recipient filters are list here: Recipient filters in the EAC. Check if you could use the organizational unit or custom attribute to meet this need.

In addition, you could also modify the smtp address for the group manually.
