1957032 - Consider deleting the source of a cross-account folder move operation

Status: NEW

(Thunderbird :: General, task)

Description

[Brendan Abolivier [:babolivier]]

When moving a folder between accounts, we create the new destination folder(s) and move the messages, but the source folder(s) stay in place.

This seems to be done on purpose, or at the very least expected, as per some comments in the backend code:

• https://searchfox.org/comm-central/rev/06d751aa65c312081d7fb2b952280250e1e8ba46/mailnews/local/src/nsLocalMailFolder.cpp#1562
• https://searchfox.org/comm-central/rev/06d751aa65c312081d7fb2b952280250e1e8ba46/mailnews/imap/src/nsImapMailFolder.cpp#7459-7460

From a user experience point of view this is a bit confusing, since I think most users would expect the source folder to be deleted from the source account, so we might want to consider changing this.
