For those that may be using the eM Client installed on a Windows computer AS WELL AS a non-365 Microsoft Outlook (Traditional Outlook) be advised that the upgrade/install of eM Client 11.x changes some registry keys that causes a major problem with Microsoft Outlook

eM Client has created a KB article about this and what needs to be done to fix it.
