Office 365 Distribution Group does not contain members when added to Skype FB online

New Contributor

Hi all,


I've created two distribution groups:


  • Exchange Online DL Group - a dist. group in exchange online admin console, populated with 2 members
  • O365 DL group - a dist. group in O365 admin console, populated with 2 members


After 24 hours (!!), I've been able to find the groups from the Skype for Business Online client and add them to the contact list. However, when exploding the group no members are listed inside.


Please help

I believe Skype for Business does not provide this feature...the idea of integrating Groups is just to start a meeting with all group members, not so group members in the client
Yeah not sure what exactly your showing there. But when creating call groups etc. pretty sure it has to be a security group not a DL.

You should be able to add both DGs and Groups to your SfB contact list. If those are newly created groups however, it might take some time for them to get synced to SfBDS, and then some more time for their membership to be reflected. But yes, it's possible:




Hello Vasil,


Actually I could verify that distribution groups can be added to the contact list with the following limitations:


  • it might take some time to be able to search for the DL in the Skype client (uo tp 24 hours)
  • you must be a member of the group in order to explode the members of the DL from the skype client
  • skype client will let you see only members of the DL which are Active Users in O365, you will not be able to see any member of type Contacts.

Do you confirm the last two points? 

I'd like to be able to browse DL even if I'm not in the DL as a member AND I'd like to see all  members of the DL from skype client (both active users and contacts)


Thanks for support



Yes, Mail Contacts are not displayed, as they are not valid object for SfB. Same goes for shared mailboxes for example. You need to be member or owner/manager of the DG for it to be displayed. Nested groups are not expanded. 


There are many other restrictions, such as a 10 DGs limit, no support for dynamic groups,  100 users display limit per group, and so on.


TL;DR version: you are tying to use the contact list in a way it has not been designed for. Adding a big number of DGs or large DGs is not recommended due to the various limitations and the fact that SfB does not respect message delivery settings configured in Exchange.
