IMAPSMTP[04/06/2019 23:16:42]:DBG:connecting to the email server...
connection timeout set: 60(seconds), 60000(milliseconds)

IMAPSMTP[04/06/2019 23:16:42]:DBG:connect failed, setting message = 0

This is happening only in 1 of the 2 Siebel Server where CommInboundRcvr is enabled and pulling emails.

2. The Internet SMTP/IMAP Server start to pull emails from the Outlook365 IMAP Servers
