Update - Microsoft 365 and Outlook

To meet increased user performance expectations, Microsoft is updating the supported versions of Outlook for Windows that can connect to Microsoft 365 services. Thus, as of 1 November 2021, the following versions of Outlook for Windows (starting with Outlook 2007, in a phased rollout) will not be able to connect to Office 365 and Microsoft 365 services:

• Office and Microsoft 365 applications Outlook for Windows version.
• Office 2007 All versions
• Office 2010 All versions
• Office 2013 versions prior to 15.0.4971.1000 of Office 2013 (Service Pack 1 with the October 2017 Update).
• Office 2016 MSI versions prior to 16.0.4600.1000 of Office 2016 (with the November 2017 update, KB 4051890).
• Microsoft 365 Apps for Business;(formerly Office 365 ProPlus) 1705 and older.
• Microsoft 365 Apps for Business;(formerly Office 365 Business) 1705 and older.
• Please ensure that the Outlook for Windows client is, or has been, updated accordingly.

Versions newer than the minimum version requirements listed above, but which are not currently supported versions, may experience connection issues.

For a list of currently supported versions listed by date, see Update history for Microsoft 365 Apps (for Microsoft 365 Apps) or Latest updates for Office versions that use Windows Installer (MSI) (see "Latest public update" for Office 2013 and 2016).

Supported versions of Outlook for Windows in Office and Microsoft 365 continue to connect to Microsoft 365 services as expected.
