I use an Active Directory group to manage agents for a Response Group. How long does it take for a newly added group member to be reflected in Skype for Business?
It takes about an hour
for Active Directory (AD) group membership updates to be reflected in Skype for
Business.
Active Directory groups
that are email enabled may be referred to as Distribution Lists (DL).
Note: All accounts added
to the group have to have Skype for Business Enterprise Voice (EV) account,
this normally entails a phone number and calling plan. Lync-to-Lync,
VoIP-to-VoIP only accounts cannot be agents for Response Groups, and should not
be added to such a group. Adding accounts that are not Enterprise Voice enabled
can negatively impact the updating of all response groups that use Active Directory
groups. If the system administrators encounter problems with invalid accounts
in a group/distribution list, they may remove your use of groups from the response
group, and ask that all changes be requested through Technology Services
Help-Desk, so accounts can be validated.
