Hi I'm not able to receive mail using the mail app in Windows 10. I can send, but messages sent to my Gmail account, (my Windows account) don't show up in Windows Mail. When I open Thunderbird they are all there. I thought that it may be deleting the mail because it gets sent to Thunderbird and then is remove from the server. I looked at my settings in Thunderbird, and contrary to my Comcast account there is no options to select Leave Mail on Server, and option that is available for my Comcast account. But to test this I closed Thunderbird, and then sent a message to my Gmail account from my Comcast account using the online mail option with Thunderbird closed. Then I opened the Mail app, and no messages were there. When I opened Thunderbird I got the "A new message has arrived", the massage appeared. I'd like to be able to retrieve my mail through both of my mail apps. I'm not sure where I should go to look for setting that would allow me to set it this way. Anyone have any ideas. The mail account it working in mail because I can send from it? Mike Ps, Looked at my Gmail account online, and there are a dozen messages in it, but none show up in the mail app. One of the problems with the Windows app is that they are so basic that you can't access any settings or options.
