There are several reasons why users may not appear in the user list:

  • Users are not licensed
  • Users have calling plan
  • An Active Directory group filter has been applied
  • Resource Accounts for Auto Attendants / Call Queues

To get more information, view the most recent Sync history from the drop down on the Sync Now button:


Please note that Microsoft will be renaming the Phone System Licence to Teams Phone Licence shortly. You may see references to both for a short while

Users are not licensed

If in the Sync log you see information like this:

<00:00> GRAPH> Enabled users: total=15, licensed=13, phoneSystem=0, excludedByCallingPlan=0, resource=0
<00:00> GRAPH> Found 0 users with a Phone System licence (none have a Calling Plan)

Then 0 users have the correct Microsoft licenses for the Teams service.

Refer to this article regarding Microsoft user licencing:

What Microsoft Licences Do I Need?

For testing and quick setup you can apply the Common Area Phone free trial to users:

Users with calling plans are excluded from the Sync Now process.

If in the Sync log a message like this can be seen:
<00:01> GRAPH> Enabled users: total=399, licensed=127, phoneSystem=108, excludedByCallingPlan=104, resource=0
<00:01> GRAPH> Found 108 users with a Phone System licence, of which 104 are excluded as they have a Calling Plan

Then this is why the users are not in the Add User list.

We advise going into the user's licence on Office 365 and removing the 'Calling Plan' (may say Domestic or International)  and running Sync Now again.

Note if users have  â€˜Communications Credit’  added to thier account, this has the same effect as a calling plan, so should be removed to make the user appear in the Add Users list.

Access this licence in the Office 365 portal for the affected users:

If the Calling Plan is not shown in this list then it may be part of a bundle SKU ans will sit in the Apps list further down the licence window above

Remove the Calling Plan, the user will then not be excluded and will appear in the list.

Press Sync Now to bring these users to the portal for setup

Calling plans are where Microsoft is providing the phone number and minutes, so probably not wanted here anyway as that's what the Call2Teams service provides using the customer's existing phone services.

An Active Directory group filter has been applied

In the Teams service tab an advanced option is available to restrict the scope of users that are synchronised into the portal to those that are members of a specific Active Directory group 

If the group has no users or does not exist, then no users will be synchronised into the Add User list. In the Sync log you will see an entry like this:

<00:01> GRAPH> Applying filter for group 'bad-group-name': include 0 of 76 users
<00:01> GRAPH> Enabled users: total=0, licensed=0, phoneSystem=0, excludedByCallingPlan=0, resource=0
<00:01> GRAPH> Found 0 users with a Phone System licence (none have a Calling Plan)

Resolve this by deleting the reference to the group from the field and use the Sync Now function again.

Microsoft Resource Accounts for Auto Attendants and Call Queues

If you are using the Auto Attendant or Call Queues in Teams Admin Center you will need to create a Resource Account and then add the "Microsoft Teams Phone Resource Account" license to that Resource account in the O365 Admin Center.
