Outlook 2019 and Exchange compatibility

Outlook 2019 supports the following versions of Exchange;

• Exchange 2013
• Exchange 2016
• Exchange 2019
• Exchange Online (Microsoft 365)

It will also support the next 2 versions of Exchange that will be coming out in the future.

Note: To determine your current version of Exchange from within Outlook see: Which Exchange version am I using?

Does Outlook 2019 support Exchange 2010?

The short answer is; It works but it is not supported.

There (currently) aren't any technical constraints in place to prevent this combination from working.

However, Mainstream Support for Exchange 2010 already ended on January 13, 2015. Extended Support originally was scheduled to end on January 14, 2020 but has recently been extended to October 13, 2020 to align it with the Extended Support end date of Office 2010.

That said, due to the fact that historically only 2 previous versions of Exchange are supported and the relative brief overlap since the release of Outlook 2019, the official stance of Microsoft is that using Outlook 2019 with Exchange 2010 is not supported.
