Question:
How do I get the new UID of an IMAP email that I copied to another folder?
I tried to use [imap Search] but it seems that the search does not allow to specify an exact time. So if someone sent me two messages on the same day with the same subject, I could not distinguish between them.
Use code like this to copy and get uid:
if (_imap.AppendMail(Mailbox, email))
newUid = _imap.AppendUid;
