Outlook accounts failing signin

nuked9

Been using Thunderbird for years with these accounts. Just today outlook accounts failing to login. Accounts do not receive email. Can not send email. Checked server settings, which were unchanged and obviously worked previously. Tried deleting passwords in password manager and re-entry. Failed. What's up with the outlook connnection?

It looks like your Outlook accounts aren’t connecting in Thunderbird. Here’s what you can try:

  1. Check Outlook’s Status: There might be issues on Microsoft’s end. Check here.
  2. Update Thunderbird: Make sure you’re using the latest version.
  3. Verify Server Settings: Double-check your IMAP/SMTP settings here.
  4. App Password: If using 2FA, try creating an app-specific password.
  5. Disable Security Software: Temporarily turn off firewalls or antivirus to check if they’re blocking the connection.

Appreciate your input. Your 'here' links inactive. I have already checked #'s 2-5. Don't know how to do #1.

Good call Ed. Read the link and gave it couple hours and logged back into Thunderbird. All outlook accounts seem to be working now. Thanks!
