Imported email accounts from Thunderbird

As a new eM Client I imported my old email data, contents etc from Thunderbird, the operation was really great. However, for some reason I ended up with two copies of every email in two special folders including two inboxes , consequently the mail pane is looking a little crowded. I tried to delete one of the special folders but this apparently in not allowed. How can I get rid of the problem folders? Should I uninstall the program and start with a fresh eM Client download, or just have to persevere.

If there are two separate folder trees for your email account, then you most likely setup the account in eM Client, and then imported it as well from Thunderbird.

Go to Menu > Accounts and see if there are two instances of the same account. If there are, remove one.

Before removing an account, make a backup using Menu > Backup.
