can not get email after latest update 154.0

have you tried the suggestions in the respective support articles.

See https://support.mozilla.org/en-US/kb/cannot-send-messages and https://support.mozilla.org/en-US/kb/cannot-receive-messages

My personal guess is if this occurred immediately after an update you probably have an antivirus problem, not a Thunderbird one. If you use any antivirus other that windows defender, try uninstalling it to see if mail just starts working again. Defender will protect you after the uninstall

I have gone through the normal troubleshooting practices prior to posting here (checking internet connection, checking email account information (address, password, etc), restarting thunderbird, etc) note: there were no issues prior to the update

thank you for the articles per the articles 1) disabled VPN - same issue (failed sending test email) 2) disabled AVG antivirus - same issue (failed sending test email) 3) checked firewall (thunderbird was NOT allowed) - same issue (failed sending test email) 4) added thunderbird to the outgoing and incoming - same issue (failed sending test email) 5) disabled firewall - same issue (failed sending test email)

all the IMAP use port 993 and are mostly gmail accounts (I did check both SMTP servers send/rec email - same fail) SMTP uses 465

so everything failed i had to remove thunderbird completely reinstall thunderbird and recreate my accounts (that sucked!!!)

everything works now, except my calendars are all messed up (they all say calendars temporarily not available) i do not like this new version so far
