Account Migration Wizard Forcing STARTTLS?

Postby m0crt » Tue Jul 05, 2016 9:54 pm

Hi All

I've managed to pull via LDAP, my accounts from my Exchange server using the Account Migration Wizard within the 8.6 console.
The next step is to pull the mail via IMAP.
Whilst I can confirm that if I telnet from the Zimbra server to the Exchange server, I can login to any mailbox and see the email (logging enabled on the Exchange Server for IMAP too)...thus this confirms connectivity from Zimbra to Exchange at a basic level. I've been using the IMAP A1 LOGIN commands to test etc.
The issue comes when I get to the 'IMAP connection details section' of the migration wizard. If I select a type of 'clear text' (port 143) I still get a STARTTLS within my Exchange IMAP server logs.

2016-07-05T21:35:23.042Z,0000000000000013,2,192.168.1.99:143,***.24.**.170:36158,,0,12,35,starttls,,

It seems that the migration wizard is attempting to us TLS no matter what.

Any ideas how I can get round this and get the mail pulled from my 2010 Exchange to the Zimbra Server.

Help VERY much welcomed...8 hours at this now. :-(

Hi!

You try to migrate from Exchange to Zimbra or vice versa?
