Microsoft retires Excel Exchange connector in April 2027 requiring workbook reconnection to new connectors
↗
Microsoft will retire the current Excel Exchange connector in April 2027, forcing users to manually reconnect workbooks to new Exchange Mail and Calendar connectors.
Engineers and administrators must audit existing Excel workbooks for Exchange connector usage and plan migrations to avoid broken data connections. The transition requires Microsoft 365 or Office 2024, adding upgrade costs or compatibility constraints. Failure to act before the deadline risks workflow disruptions for users relying on Exchange data in Excel.
