I had a huge problem with M Outlook. In addition it has locked me out of my Office 365 package and I'm not getting help or support. Luckily I had backup completed before the problem. I changed to Thunderbird (using pop3), which I find very good. The back up is approx 8 GB but with many duplicates which I need to clean up. When I click import it seems to limit the file size to 2 GB. How can I import this backup file into Thunderbird to enable me to access the emails, clean up the many many duplicates and reduce the size? I await help, Thanks in advance

Is this a backup of a Thunderbird profile? Is it a zip file? If so, I suggest unzipping and use the tools>import>import from another thunderbird installation menu option.

Thank you for responding. The backup file is from M Outlook. When I try to import it the menu doesn't display it using Thunderbird profile or "Import from a file". I just spoke to my email service provider and they have my emails through some internal imap feature? They will forward them to me later but I'm not sure in what format, presumably through a zip file and csv or pst? l am not sure what to do from here. M

To use the current file, we would need to know its format. Thunderbird does not directly support importing Outlook pst files, but there are ways to do that. When you receive the new file, post what format it is and maybe we can help then.
