Hi Pavel,
Ok, that worked.
I added some special markers before and after the call to Download so I could find it in the debugging text. Here's what I get:
***
IMAPX21 UID FETCH 392 ()
IMAPX21 BAD Error in IMAP command UID FETCH: FETCH list is empty.
***
This resulted from a call toMessage.Download(ImapX.Enums.MessageFetchMode.Full)
Does this tell you what you need to know? I can still send you the log file as you indicated, but as it will take a lot of redacting to get sensitive info out, I wanted to see if this told you what you needed already.
