Mailbox Configuration in SugarCRM 14.0.0 version

Hi All,

We have recently upgraded one of our production instance, currently it version is sugarcrm ent 14.0.0

system is up and running fine, however we have one issue i.e email notification is not works.

we have tested via "Send Test Email" button in system email setting, we got below error message




FYI, below are the mailbox configuration, and it was working fine in previous versions, but currently same setting given us error.







We tried also to add connector setting via Microsoft azure but we don't have SSL certificate that's why we are unable to configure with MS.
Azure.

Please suggest us how we can fix the reported issue without SSL cerfitcate, as in the previous version mailbox works with same setting which is showing in the attached screenshot.


Any Suggestion would be highly appreciated.

Thank You in Advance
