How to check a mail message UID exist or not using JavaMail?

Please help me out how to find the mail exists or not.

Description: I've deleted a mail but I've it's UID. Now how can I check whether a mail exists.

Solution

  • If you just marked it DELETED, you can still find it by searching for it by UID, see UIDFolder.getMessageByUID.

    If it was deleted by moving it to a Trash folder, the UID won't help you. You'll need to search for it using some other attributes of the message such as the Message-Id.

    If it was deleted and expunged, it's gone forever.
