I just saw that MS is no longer offering stand-alone versions of their Office products. I've always used them because I'm familiar with them and basically like them. I was going to grab a copy of Office 2019 (currently using 2010) while I still could but I started to think that since I'm no longer working and funds are getting tight that I'd like to switch to an Open Source solution. But, I still need to find a free, secure open source email client that I like. Suggestions?
