Hi all: The following question is from Zendesk. I am adding it here so we can have the benefit of a public discussion with our awesome Thunderbird Support Community. '''tl;dr''' Try [[Troubleshoot Mode Thunderbird|Thunderbird Troubleshoot mode|] and see if that helps. Also try disabling all 3rd party software (e.g.anti-virus, firewalls, etc). If it is a password issue, please ask your email provider e.g. Optus or gmail to reset the password for you. Double check your Optus settings at: https://www.optus.com.au/support/answer?id=1434 and double check your gmail settings: https://support.mozilla.org/en-US/kb/thunderbird-and-gmail '''We've found over the years that troubleshooting is often difficult. It would probably speed things up if you could find somebody who's more technical in your community to help you in real life.''' If the '''tl;dr''' doesn't help, please give us more troubleshooting details (without this level of detail we can't help you further): # Please let us know your email provider, is it gmail, optus or both? # Please let us know what operating system e.g. macOS Ventura, Windows 11, Ubuntu 22.04 # Please let us know what 3rd party software like add-ons, anti-virus or firewalls you are using (and please try disabling them and see if that helps) # Finally, please let us know what steps you followed exactly, what you expected and what actually happened. '''Text from Zendesk''': * "email address" cannot connect to Google when you said I would be able to canot recall my PASSWORD cannot send or receive mail from THUNDERBIRD all settings are CORRECT" * "am still unable to open or send my Mozilla mail my IP is Optus my address email at optus address. Optus cannot understand WHY I cannot open Mozilla Mail the setting are correct , this has been going on for months ! What is the point of me having Mozlla mail that will not open or send? I know my password for Optus, but Mozilla keep putting the message up INCORRECT Optus fail to understand , they suggest you email me and give me the original password I gave when I commenced with Mozilla mail, because it was SO LONG AGO I cannot recall the password I joined Mozilla with." * "I still cannot open or send from my Mozilla Mail and my server Optus have had a Technician check and it is not Optus the problem is MOZILLA I urgently need to keep in touch with family.
