Windows Mail App Bug - Not sending e-mails from Gmail accounts
Hello, everyone! I'm a long-term user of the Windows Mail and Calendar app, and it has always worked like a charm for me. However, something happened recently and now every time I try to send away an e-mail from a Gmail account, I got a message saying: "There was an error sending your message". Everything else works: I can read new e-mails normally, and the other e-mail services attached to the app still fully functional (Outlook, Office360, Yahoo). I also noticed that when I try to send an e-mail from a Gmail account, what I wrote goes to the "Draft" folder. I can even access the "draft" on the Gmail website, but when I open it, the formatation is completely crazy. I got a Dell XPS 13 9370, and I'm running the latest versions of both Windows 10 and the Mail and Calendar app. I've tried everything I could: 1) I removed the Gmail accounts and added them again but the problem persists; 2) I uninstalled and reinstalled the "Email and Calendar" app but the problem persists; 3) I disabled the antivirus and the firewall but the problem persists (I got a kaspersky); 4) I have already run system corruption checks at the command prompt, but nothing has been found; What should I do? This is the pop-up that appears (I'm a Brazilian user, so it is in Portuguese):
