 A recent fix has addressed an issue where some Guest users were being omitted from the output of the Get-CsOnlineUser cmdlet, resulting in an increase in the reported user count.
 
+**Updates in Teams PowerShell Module version 6.1.1 Preview and later**
+
+The following updates are applicable for organizations that use Microsoft Teams PowerShell version 6.1.1 (Targeted Release: April 15th, 2024) or later. These changes will be gradually rolled out for all tenants starting from April 26th, 2024. 
+
+When using the Get-CsOnlineUser cmdlet in Teams PowerShell Module without the -identity parameter, we are introducing these updates:
+- Before the rollout, unlicensed users who did not have a valid Teams license were displayed in the output of the Get-CsOnlineUser cmdlet for 30 days after license removal. After the rollout, Get-CsOnlineUser will show unlicensed users after the initial 30 days and also include unlicensed users who never had a valid Teams license.
+- The AccountType value Unknown is being renamed to IneligibleUser, and will include users who do not have a valid Teams license (exceptions: Guest, SfbOnPremUser, and ResourceAccount).
+- You can exclude users with the AccountType as IneligibleUser from the output with the AccountType filter. For example, Get-CsOnlineUser -Filter {AccountType -ne 'IneligibleUser'}
+
+When Get-CsOnlineUser is used with the -identity parameter, you can also use UPN, Alias, and SIP Address with the -identity parameter to obtain the information for a specific unlicensed user.
+
+**Updates in Teams PowerShell Module version 6.1.0 and later**
+
+The following updates are applicable for organizations that use Microsoft Teams PowerShell version 6.1.0 or later.
+
+- LocationPolicy: LocationPolicy attribute is being deprecated from the output of Get-CsOnlineUser in all clouds. Get-CsPhoneNumberAssignment -IsoCountryCode can be used to get the LocationPolicy information. (Note: LocationPolicy attribute will no longer be populated with value in the older Teams Powershell Module versions (<6.1.0) starting from 20th March 2024.)
+
+- OptionFlags: OptionFlags attribute will no longer be populated with value in the output of Get-CsOnlineUser in all clouds. It's important to note that other details besides EnterpriseVoiceEnabled, previously found in OptionFlags, are no longer relevant for Teams. Administrators can still utilize the EnterpriseVoiceEnabled attribute in the output of the Get-CsOnlineUser cmdlet to get this information. (Note: This change will be rolled out to all Teams Powershell Module versions (=<6.1.0) starting from 20th March 2024.)
