How to update or modify wrong Chat email address on Microsoft Teams

Richard Li 10

My issue is similar to one previous post. One user's Teams chat email is wrong. I checked AD, Exchange On Prem and Online (A hybrid environment), and found and changed the wrong SIP address in ExchangeOnline. 3 days later, both wrong and correct chat email addresses are still showing on Team's contact. Azure's IM address is also showing the wrong address.

Run the Powershell suggested by some experts here with anotehr post:

Connect to Microsoft Teams

$credential = Get-Credential

Connect-MicrosoftTeams -Credential $credential

Get the user's SIP address

Get-CsOnlineUser -Identity "******@domain.com" | Select-Object SipAddress

Update the user's SIP address

Set-CsUser -Identity "@domain.com" -SipAddress "sip:@domain.com"

Confirmed that the SIP address is still wrong, however the Set-CsUser command giving me error: Set-CsUser: A parameter cannot be found that matches parameter name "SipAddress".

Any other suggestions? Or the sync will take much longer than 3 days?

Hi @Richard Li
Could you please tell me if you have tried to log out of Teams and then log back in.

As the post you mentioned says, please log in to the Microsoft Entra Admin Center and follow the steps to modify the property information. It will take some time to implement the information changes in Teams.

If you have tried to change the property information in the Microsoft Entra Admin Center, but it did not work, we recommend that you contact the telephone support, who will help you collect logs to retrieve the problem.

Admins, have your account details ready when you call.

Answer 1

For anyone stumbling on this, we had the same problem in our hybrid enviroment.

The Set-CsUser Command is deprecated and doesn't work
There was no msRTCSIP-PrimaryUserAddress in the ADUC
We couldn't edit the properties neither in Entra nor in Exchange online

The solution was to update the SIP Adress via our local Exchange.

Either through the GUI:
User Attributes -> E-Mail-Addresses -> Remove old entry for SIP:*****@domain.com*

Or

via the Exchange Management Shell with the Set-RemoteMailbox Command:

Check if there is an alternative SIP-Address available
Get-RemoteMailbox -Identity ******@domain.com | Select EmailAddresses
Or
Add the SIP-Address directly (If it already exists, you'll get a warning that the command ran without any changes)
Set-RemoteMailbox -Identity ******@domain.com -EmailAddresses @{add="sip:******@domain.com"}
Remove the old SIP-Address
Set-RemoteMailbox -Identity ******@domain.com -EmailAddresses @{remove="sip:old.user@domaincom"}

After a few hours this should sync and the correct Chat Address should be displayed in Teams.

@Robin Sheng-MSFT. Thanks. I sorted it out later.

Just want to put an update here for others having the same issues. The solution for me is to edit in AD through ADUC.

Open ADUC and go to the user's properties.
In the Attribute Editor, check the value of msRTCSIP-PrimaryUserAddress to ensure it's set as expected.
