About Classic Outlook Integration
The Outlook Plugin installation changed in Sage CRM 2020 R1. In previous versions, the installation of both the classic and lite Outlook plugins was handled using ActiveX. This dependency on ActiveX had required our customers to use Internet Explorer to use install the Outlook plugin. Since Sage CRM 2020 R1, the installation can be carried out by users of any browser.
Note: The Sage CRM Outlook plugin still has a dependency on ActiveX and IE11 for certain operations, but this is for background tasks. The user can continue to use Chrome or their browser of choice as their user interface with Sage CRM.
