Got Different Email Subject While Retrieve Using Mailkit

Question

Currently I'm trying to retrieve email message from outlook o365 using Mailkit 3.4.2 and connect via IMAP. When I try to get the message detail, there is different value between the original email Subject with what I got using Mailkit.

there is something like $B!> (B replacing the - char. Anyone has encountered some problem like this?

Answer 1

It looks like your original subject has escape sequences in it ( is the Escape key encoded in Unicode).

What does the raw subject look like?

If you open the message in a text editor, does the subject appear as binary garbage? Or does it look more like “=?iso-2022-jp?b?base64blob?=“?
