Форум поддержки Thunderbird

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

bij het importeren van adressen is het misgelopen. Er waren een 90 tal adressen en na de bewerking vermeldt het systeem een 2700 adressen. de teksten waren niet leesbaar: alle letters dooreen. Die kan ik nu niet verwijderen

'''When are you going to add Categories to Contacts? '''

It is the only feature holding me back. I use outlook for Windows and I am able to sort my contacts by categories. In addition, I use a syncing software called Companion Link/Deja Office which syncs those contacts with those categories on either my iPhone or Android. This allows me to focus on targeting specific people for either personal or business use. Your software has that feature for calendar items. Why not integrate that same feature for the contacts which has a higher degree of importance. I see that a multitude of people have asked for quite some time already even offering to donate money if implemented.

Thanks so much :-)
