messages

The messages API first appeared in Thunderbird 66.

Note

When the term messageId is used in these documents, it doesn’t refer to the Message-ID email header. It is an internal tracking number that does not remain after a restart. Nor does it follow an email that has been moved to a different folder.

Warning

Some functions in this API potentially return a lot of messages. Be careful what you wish for! See Working with Message Lists for more information.

Permissions

messagesMove
Move, copy, or delete your email messages
messagesRead

Note

The permission messagesRead is required to use messages.
