Locate path in your project:

vendor/uvdesk/mailbox-component/Console/RefreshMailboxCommand.php

Open RefreshMailboxCommand.php and make changes here as suggested below.

$imap = imap_open("{xx.xx.xx.xx:993/imap/ssl/novalidate-cert}", 'mydomain/user', 'password', NULL, 1, array('DISABLE_AUTHENTICATOR' => 'GSSAPI'));

Hope it will help to resolve for Exchange server !!

Hi @Sanjeev

Thanks it was helpfull for me !!!
I would suggest to only append , NULL, 1, array('DISABLE_AUTHENTICATOR' => 'GSSAPI'));
to the existing value and modify if necessary the username/password/url directly in the uvdesk_mailbox.yaml config file.

@Makss
Yes, as {xx.xx.xx.xx:993/imap/ssl/novalidate-cert} we have added novalidate-cert so write down whole string for this.

@Sanjeev yes, or you can add it from the web interface !
Anyway, no error about Kerberos anymore, but on my side, i'm not able to get the ticket created from the mailbox... But it's another story !
