Skype/Teams Hybrid Precense

[JeroenKIT1605]

We are in the proces of migration to Exchange Online & Teams. All the hybrid setup steps have been completed and we are now in the proces of moving users from Skype for business server 2019 to Microsoft Teams.

The current setup is as follows:

• Azure AD connect is synchronizing between AD and AAD
• Exchange Server 2016 is setup in Full Hybrid Classic mode
• Skype for Business Server 2019 is setup in hybrid mode with Teams

We are able to move user between Skype On-premisse and Teams using de Skype MACP and with powershell. When moving users to Teams they can no longer find internal Skype users. While internal Skype users can still contact the migrated users (which are in now in TeamsOnly mode). Once the internal chat has been initiated the Teams user can use that chat to write back messages. However, when searching a user in Teams they all show up as offline / presence unknown.

Maybe you guys have an idea how we can get can TeamsOnly users to communicate to Skype on-premisse users. We have already checked the connection and we can migrate users back and forward between Skype on-premisse and Teams online.

@JeroenKIT1605 Is AzureAD Connect configured to synchronize all users and is there any attribute filtering configured to not sync Skype/Lync attributes ?

[#3]

Only 450 out of 977 skype users have been synced and all msRTCSIP attributes have been synced ten minutes ago.

[#4]

@JeroenKIT1605 Firewalls dropping anything ?

[#5]

We did not find any blocks of droppes in the fortigate.

[#6]

It seems that the Proxyaddess attribute does not synchronise to azureAD. Nor does the msRTCSIP-PrimaryUserAddress synchronise. They both have the same value and are added to AAD connect.

What mode are your SfB users in? If it is Islands it works as designed. Teams will only try to connect to Teams in this case. If you want Teams only users to chat with SfB users, the only way is to enable one of the SfB modes (SfB only, SfB with Teams collab/meetings) for the SfB users in Teams... https://docs.microsoft.com/en-us/microsoftteams/teams-and-skypeforbusiness-coexistence-and-interoper...

The tenant itself is currently set to "Island mode".  When migrating users from Skype for Business server to Teams using the Skype for Bussiness Admin center (on premisse) the users are automatically set as TeamsOnly in the tenant. We did not use the Move-CSUser command but used the GUI to migrate users. The two different types of users are mentioned below using the Get-CSOnlineUser command.

On premise Skype user which was migrated from on premisse to Teams:

• InterpretedUserType : HybridOnlineTeamsOnlyUser
• TeamsUpgradeEffectiveMode : TeamsOnly

On-premise Skype user which only synced to AAD and not migrated to Teams:

• InterpretedUserType : HybridOnpremSfBUserWithTeamsLicense
• TeamsUpgradeEffectiveMode : Islands
