M365 Changelog: Limiting the maximum supported value for StartRow to 50,000

MC235978 – We have updated this post to ensure visibility. No changes have been made to the content below. Thank you for your patience.

We’re making some changes to SharePoint Online Search. To continue to provide a high performance search experience, we’re limiting the maximum supported value StartRow to 50,000.

Key Points

• Timing: Starting late February 2021 through late May 2021 
• Action: review and assess for your organization

How this will affect your organization:

As part of this configuration change, users who run queries using the StartRow parameter (at rest API) with values exceeding 50,000 will be throttled. All queries using StartRow (< 50,000) – will not be impacted.

What you need to do to prepare:

To not be throttled, review StartRow parameters and limit to (< 50,0000).  For search results (> 50,000), please follow Pagination for large result sets instead of the StartRow approach.
