"Contacts" in distribution lists in M365

[Jawloms]

We used to have Exchange on-site and migrated up to M365 a couple of years ago. AD syncs up to M365.

 

We have some "Contacts" in AD which are governors' personal email addresses. We then have a distribution list called "Governors personal addresses" which we send an email to saying "There is something in your school mailbox, go look at it", cos apparently asking them to just check their school mailbox occasionally anyway is too much. There are 9 contacts in this distribution list. When we send to that list, some of the people in it receive the email, others don't. Having had a look in to it, when I look at the "Members" of the list, the ones who receive the emails have an email address under their name, the ones who don't, don't, which makes sense. However, from what I can see the contacts in AD which work are setup identically to the ones that don't. And in M365, when you go to "Users" -> "Contacts" you can see the email addresses in there against the people's names. Why would the email address not be showing when viewing the members of the DL?

If you still have an on-prem Exchange server use ECP  to make the contacts. Using ADUC to make a contact produces something that looks superficially correct but does not work. 

 

I've not tried the PowerShell equivalent, which claims to work for EOL too. New-MailContact (ExchangePowerShell) | Microsoft Learn

The onsite Exchange is powered off and has been since we migrated. I believe the contacts in question were created before we migrated. It just seems odd that in one place in M365 they do show an email address, and in another they don't.

 

I'll give the PowerShell command a go, thank you.
