Review for ImportExportTools by jrial
Rated 1 out of 5 stars
Tried exporting entire locally cached mailbox to which I lost access, doesn't work. Tried importing hierarchy representing a mail account. Apparently that's not possible: you have to create every folder manually and import separately. Tried importing a single email into an Exchange mailbox, no go, and no error message either.
This review is for a previous version of the add-on (3.3.0).To create your own collections, you must have a Mozilla Add-ons account.
