Reason being, we’ve seen that the SfB client can sign in and interfere with the Teams audio device and sometimes reinitialize the device driver and hang up your Teams call. Unless you are participating in a lot of externally invited SfB Server calls, my recommendation is to uninstall the SfB client. Figure 2: Teams Only mode in the SfB Client. If you are collaborating with someone still on SfBS, then you must invite them to a meeting where you join via the SfB web client, or they can join a Teams meeting you invite them to. The requirement is that both sides are in Teams Only mode.

From there you can create a list of users where you can use the New-CsBatchPolicyAssignmentOperation to bulk assign the Teams Only mode policy. The Grant-CsTeamsUpgradePolicy article has some good examples of how you can identify all users and their TeamsUpgradeEffectiveMode. If your users explicitly have assigned modes different from the tenant standard, then you need to set these users to Teams Only mode. Set-CsTeamsUpgradePolicy -PolicyName UpgradeToTeams -Global Here’s how you check it and set it to False using the Teams PowerShell module: If this setting is set to True, it means that at some point you had a Hybrid SfB setup and never turned it off. When these records are implemented, and all are pointing to Microsoft 365, there is one more setting you can triple check which is the SIP shared namespace setting for your tenant. CNAME handles sign in for the SfB client.CNAME handles sign for the SfB client and specifically the SfB mobile client._sipfederationtls handles federation in Microsoft Teams._sip._tls SRV record handles sign in for the SfB client.$CountSIPDomains = (Get-CsOnlineUser -Filter įor the remaining domains that are SIP enabled, you need to make sure the following DNS records exist: #Get all entities in your tenant that has a sip address populated, may take some time if you have tens of thousands of users #Connect to the Microsoft Teams PowerShell module Just make sure you have the latest Teams PowerShell module to perform the below PowerShell operations first, since the SfBO PowerShell module is decommissioned. This is a straightforward way to determine if you have any verified domains in your tenant that are SIP-enabled, but not in use. If you’ve verified domains in your tenant, but are not using them for SfBO and Teams, you can disable them for this functionality by running the Disable-CsOnlineSipDomain cmdlet. If you are in Exchange hybrid mode, consider completing the migration to Exchange Online before going to Teams Only mode.īefore you can set the TeamsUpgradePolicy to Teams Only mode, you need to comb through all active SIP domains and make sure the DNS exists and points to SfBO.Plan to uninstall the Skype for Business (SfB) client.Make sure users with other TeamsUpgradeEffectiveModes are also updated.Set the global TeamsUpgradePolicy to Teams Only mode.Make sure SharedSipAddressSpace is set to $False.Validate DNS records for all enabled SIP domains.

There are ways to flip your tenant over to Teams Only mode yourself, and those steps are outlined below: If necessary, you do not have to wait for Microsoft to help you with the transition.

Figure 1: Microsoft Teams Upgrade Message. During that time, Microsoft will help flip your tenant to Teams Only mode for all users homed in Microsoft 365.Īfter that period, all other modes like Islands, Meeting First, or Meeting and collaboration will not be available options for your users, as these modes were just steps along the way to Teams Only mode. To find the date specified for you, navigate over to the Teams admin center. Microsoft will offer assisted transitions for your tenant during specified periods. Teams Only mode will be the only option for users homed in Microsoft 365. So, what does that really mean? It means just that, SfBO will not be available in Microsoft 365 anymore. Soon July 31 st, 2021, will be here and the official Skype for Business Online (SfBO) retirement day looms closer.
