Bugzilla

Steps to reproduce:

I tried importing various top level folders on another computer with an existing install (v128.1). These imports failed. Messages did not become available. This issue may be related to bug 1907984 .

Reproduce using a sbd folder containing mailbox files and structure:
#method 1
Import from another Thunderbird installation
Choose a profile folder
Select Mail Messages
Start Import
Finish (restarts)

#method 2
Import from a file
Import backed-up Profile
Choose a profile folder
Select Mail Messages
Start Import
Finish (restarts)

This creates empty Thunderbird Import and Thunderbird Import1 numbered folders that are empty. I tried to import copied local folders too with the same result.

Manually copying mbox files did not work either.


Actual results:

Importing mbox files did not work.


Expected results:

Importing mbox files should work.
