As mentioned in my previous posts:
Enabling user for Teams Enterprise Voice fails with: "Management object not found for identity"
http://terenceluk.blogspot.com/2020/10/enabling-user-for-teams-enterprise.html
… a user who has previously been enabled for an on-premise Skype for Business Server may still have the msRTCSIP-DeploymentLocator attribute populated with the value SRV: even after they have been removed from the on-premise SfB Server.
Having this value in their user account would prevent them from being enabled for Enterprise Voice in Microsoft Teams and the quick resolution for this would be to remove the attribute, for and AD Connect sync, then try enabling them again.
This solution may be viable for a few accounts but not practical when the amount goes up to the 100s or 1000s so I decided to create a few PowerShell cmdlets to automate the process.
Find SfB Enabled with msRTCSIP-DeploymentLocator Configured Accounts
Get-ADuser -Properties msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled -Filter {msRTCSIP-DeploymentLocator -like "*" -and msRTCSIP-UserEnabled -eq $true } | Select UserPrincipalName,msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled
Find SfB Enabled with msRTCSIP-DeploymentLocator Configured as SRV: Accounts
Get-ADuser -Properties msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled -Filter {msRTCSIP-DeploymentLocator -eq "SRV:" -and msRTCSIP-UserEnabled -eq $true } | Select UserPrincipalName,msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled
Find SfB Disabled with msRTCSIP-DeploymentLocator Configured as SRV: AND empty msRTCSIP-PrimaryHomeServer Accounts Export as CSV
Get-ADuser -Properties msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled -Filter {msRTCSIP-DeploymentLocator -eq "SRV:" -and msRTCSIP-UserEnabled -notlike '*' -and msRTCSIP-PrimaryHomeServer -notlike '*'} | Select UserPrincipalName,msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled | Export-CSV C:\temp\SRVaccounts.csv
Find SfB Disabled with msRTCSIP-DeploymentLocator Configured as SRV: AND empty msRTCSIP-PrimaryHomeServer Accounts and Clear value
**The following cmdlet modifies accounts and I would recommend to export them to a list and review prior to making the changes**
Get-ADuser -Properties msRTCSIP-DeploymentLocator,msRTCSIP-PrimaryHomeServer,msRTCSIP-UserEnabled -Filter {msRTCSIP-DeploymentLocator -eq "SRV:" -and msRTCSIP-UserEnabled -notlike '*' -and msRTCSIP-PrimaryHomeServer -notlike '*'} | Set-ADUser -Clear msRTCSIP-DeploymentLocator
The following are the output of some of the cmdlets above.
