Hi,

Using Exchange on premise and cloud.

I created contacts in AD, that have external emails e.g. xx@gmail, xx@yahoo.com and add them to a distribution group that has a couple of domain user email as well. when i go to the on premise emc or cloud emc under group section i see the both all the users listed in the group but when i open outlook and input the group and expand it, i only see the domain user emails or none.

kindly see the pics. 

i would like to know why i cannot see the external contacts? i tried running some commands on exchange powershell of updating address list but in vain. am i missing something out?

regards,

Khuz

Hello

tip: try delete autocomplete entry for this group in outlook.
and check contact exchange attribute with get-mailcontat -ResultSize unlimited | set-mailcontact

Hi,

I can reproduce your issue when the contact which is added in the distribution group is set to hide from address lists. Once I uncheck Hide from address lists for the contact, the distribution group can be expanded in Outlook.

Please check whether the contact is set to hide from address lists in your scenario. Also run the following command:

Get-DistributionGroupMember xxxxOUTSOURCE

Re

Hi

As per the information and details provided by you, to display the contacts in distribution groups, please follow these steps: -

This cmdlet is available only in on-premises Exchange Server 2013.

Use the Enable-DistributionGroup cmdlet to mail-enable an existing universal group.

I hope this information will be helpful for you.

Thanks and regards

Hi Winnie and Shweta,

i ran the command enable-distirbution group...it is already mail enabled

i also ran the command Get-DistributionGroupMember xxxxOUTSOURCE it does show me all the users listed. however i am not able to get the option of unchecking hide from address list in the contacts created. 

What Winnie is saying is that there are members of your distribution group that are "Hidden from Address Lists" and if you want to expand the group, you need to unhide those users. First thing I would do is to check to see if you have any users from the address lists.  You should be able to do that by using the following command:

Get-DistributionGroupMember "Group Name" | where {$_.HiddenFromAddressListsEnabled -eq $true}

Once you do that, as a test you can try enabling the mailbox/contact to be seen in the address books (use Set-Mailbox and Set-Mailcontact to do this).

If that works, then we know the issue.  I don't have the contacts inside of MSFT to see if this is by design or not, but if it is a requirement to have these addresses hidden and still be able to expand the dl, then you may need to contact MSFT to see if this by design or not/possibly get a fix or an enhancement request for a future version of the pr

Hi Khuzema R,

Has the issue been resolved? 

Please try Hinte's command to check the group members. And waiting for your updates.
