MC950880 - Update to Get-CsPhoneNumberAssignment

Updated February 20, 2025: We have updated the rollout timeline below. Thank you for your patience.

To maintain the best performance and reliability of our service, we are updating the page size limit for the phone number retrieval API (Get-CsPhoneNumberAssignment cmdlet) to a maximum of 1,000 numbers per query.

When this will happen:

General Availability (Worldwide, GCC): We will begin rolling out early February 2025 (previously mid-January) and expect to complete by late February 2025 (previously mid-February). 

How this will affect your organization:

From January 6, 2025, any request with -Top parameter exceeding 1,000 will result in a "Bad request." Please ensure that your Get-CsPhoneNumberAssignment requests do not surpass this limit. If the intended operation is to export your numbers, please use https://learn.microsoft.com/en-us/powershell/module/teams/export-csacquiredphonenumber?view=teams-ps

What you need to do to prepare:

Please ensure that your Get-CsPhoneNumberAssignment requests do not surpass this limit.
