I need something to replace Outlook, INCLUDING THE CALENDAR, so that I can sync between a Windows computer and an Android phone.  eM Client is not in the Android Play Store.  Is there another way to use it on an Android phone and tablet?  Without calendar syncing, the program is useless to me.

Hi Kris,
I just installed eM (yesterday) and imported data from Thunderbird. I am delighted to see that the events from the Google calendar that I share with my wife have appeared on the right sidebar under ‘Agenda’, so don’t give up. It must be possible.
Oh! And there is a link in the left sidebar that displays the Google calender content in the central column.
And now I have just noticed that you can ‘Add a new task’ which also appears in the same list. Can’t see any way yet to add a new Event.
