I have got the error response when fetch email message with IAMP protocal by program, and fetch the empty email message.
Error response: Retrieval using the IMAP4 protocol failed for the following message
Exchange server version: Exchange2019
Scenario: emails with large header of X-Microsoft-Antispam-Message-Info, but other emails with small header of X-Microsoft-Antispam-Message-Info can be fetched.
Many thanks for you help!
