Exchange online support for Outlook 2010

Question

I cannot find any Microsoft documentation that clearly states that Exchange Online supports Outlook 2010 even though some threads indicates that some are doing this. IS there any URL showing Microsoft's official stance on this matter? Other asked the same question and the answer came back referring to Exchange 2016 and Exchange online - but 2010 nowhere specifically mentioned.
Please advise.

Hi @Dorothea Antoinette Smit ,
According to the Microsoft official article, we could know:

Starting on November 1, 2021, the following versions are the minimum versions of Outlook for Windows you need to be using to be able to connect to Microsoft 365 services, such as Exchange Online:
Version 1706 of Microsoft 365 Apps
Version 16.0.4600.1000 of Office 2016 (with the November 2017 Update, KB 4051890)
Version 15.0.4971.1000 of Office 2013 (Service Pack 1 with the October 2017 Update, KB 4043461)

All versions of Outlook 2019 should be able to connect to Microsoft 365 services, but only the most current version is supported.
Even though newer versions of Outlook 2013 might be able to connect to Microsoft 365 services, it's not supported and you may encounter performance or reliability issues.

For more information you could refer to: Office versions and connectivity to Office 365 services

Answer 2

Outlook 2010 will no longer be able to connect to Exchange Online, so your emails within the Outlook 2010 app will stop working. (Although this particular change has been delayed until 2021).
Thanks
