Reminder: Update to Microsoft 365 and Outlook for Windows connectivity
30-day/Final Reminder (MC229143 - DEC '20 and MC274503 - July '21): To ensure that we meet performance expectations, we are updating the supported versions of Outlook for Windows that can connect to Microsoft 365 services.
Starting November 1, 2021, the following versions of Outlook for Windows, as part of Office and Microsoft 365 Apps, will not be able to connect with Office 365 and Microsoft 365 services.
How this will affect your organization:
Versions that are newer than minimum version requirements listed above, but are not the currently supported version, may experience connectivity issues.
To see a list of the currently supported versions, visit Update history for Microsoft 365 Apps (listed by date) (for Microsoft 365 Apps) or Latest updates for versions of Office 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 will continue to connect to Microsoft 365 services as expected.
What you need to do to prepare:
We recommend that all users upgrade to the supported versions of Office and Microsoft 365 Apps.
