OK so heres my problem I have 3 gmail accounts, all configured to work with my Thunderbird client 78.12.0 (64-bit) on Windows 10. One of which will not recieve or send emails. Every time I try I'm asked for the password. The other 2 work just fine both recieving and sending, weirdly they have different smtp settings which are, 1. recieve imap.gmail.com - port 993 - Normal password - SSL/TLS 1. send smtp.gmail.com - port 587 - Normal password - STARTTLS 2. recieve imap.gmail.com - port 993 - Normal password - SSL/TL. 2.send smtp.gmail.com - port 465 - Normal password - SSL/TLS 3 The one that isn't working I have tried a combination of both and now its configured thus recieve imap.gmail.com - port 993 - Normal password - SSL/TLS send smtp.gmail.com - port 465 - Normal password - SSL/TLS But as I say Ive tried a combination of both also tried all recomdations from these pages https://support.mozilla.org/en-US/kb/cannot-send-messages and https://support.mozilla.org/en-US/kb/cannot-receive-messages I tried deleting the passwords and all other things mentioned but nothing seems to work I can log into the web mail for this account so its not that.Or should I delete this account off Thunderbird and make a new one? any help greatly appriciated Thanks
