Stock History Excel feed not working after 7th September 2026

This appears to be a service-side issue affecting Excel stock data features rather than a workbook formula syntax problem.

Supported facts from the available information:

• Similar incidents have been reported where Stock Data Type and STOCKHISTORY stopped returning data and showed server-related errors.
• In those cases, there was no published timeline for restoration.
• The recommended path is to report the issue through the Microsoft 365 Admin Center so it can be tracked by Microsoft’s service teams.

Recommended actions:

1. If the workbook uses STOCKHISTORY, verify the date argument is not being passed as locale-dependent text.
   • Use DATE(...) instead of a text date.
   • Example: =STOCKHISTORY("IBM",DATE(2026,9,7),TODAY(),1,2)
   • This avoids failures caused by regional date parsing.
2. If formulas that previously worked now stop returning data only after 7 September 2026, treat it as a likely backend data/feed problem.
   • Wait and retry after some time.
3. If the issue continues, have a Microsoft 365 admin report it:
   • Open Microsoft 365 Admin Center
   • Go to Health
   • Select Service health
   • Choose Report an issue
4. From Excel, use Help > Send feedback to submit the problem to the product team.

If the workbook was migrated from Google Sheets and uses unsupported finance functions, Excel for the web supports alternatives such as the Stocks data type for current market data, and STOCKHISTORY for historical data.
