Here's Your Reminder to Update Microsoft 365 and Outlook for Windows Connectivity

Update to Microsoft 365 and Outlook for Windows connectivity...

To ensure that Microsoft meet performance expectations, they are updating the supported versions of Outlook for Windows that can connect to Microsoft 365 services.

From November 1, 2021, the following versions of Outlook for Windows, as part of Office and Microsoft 365 Apps, were no longer able to connect with Office 365 and Microsoft 365 services.

If organisations do not update, they may over time, encounter performance or reliability issues. Organisations that use these older clients will almost certainly face an increased security risk and may find themselves out of compliance depending upon specific regional or industry requirements. Therefore, administrators should update older Office clients to versions of Office supported for connecting to Microsoft 365 services.
