I'm asking this question so I can post some helpful information for people wanting to create a backup of their profile.

If you are using Windows OS and you got your download from the official website: https://www.thunderbird.net/en-US/thunderbird/all/

How do you locate the correct folder to backup? The backup must contain everything, profiles, mail accounts, emails, address books, calendar, preferences - the lot. The backup can be used to transfer between computers.

I had to log in this morning, the first time as its automatic, and when i did all my folders and emails have gone. Where are they as there is important information in there which i need. The page layout is different too as i can't delete anything. HELP

I'm having a connectivity issues. Did some searching which directed me to the Appdata Profiles folder. When looking inside I see Mail and ImapMail. Both have numerous folders inside. Too may I believe. Based upon the screen prints of the folder's contents, do you see conflicts?

I have three email addresses with Outlook.com.

Pop.windstream I have not used in many years. Not sure what others I could possible delete.

Thanks.
