Need more details on O365 - Basic Authentication Deprecation


Could you elaborate on the basic authentication deprecation mentioned in the 8.0.3 release notes… ? When is it occurring?

Do clients on-premise are currently still on 7.18.5  until 8.1 is released ( waiting code being stabilized with new features and fixes), do we need to update their system in 8.0.3 or does the email listener integration with 7.18.5 work ok ?

Hello, Damien!


As for now, the integration works successfully on all versions with Basic Authentication, and it does not depend on where the site is (cloud or on-premise). 

But as we have written in the release notes 8.0.3 Microsoft is deprecating the login and password authentication (Basic Authentication) method since it is obsolete and insecure. We recommend setting up secure OAuth authentication in the near future so that you do not lose access to your mailboxes from Creatio. 

Also, you can change the method of authentication both on version 7.18.5 and on 8.0.1, it will work.


You can use this article for setting up Microsoft Office 365 Email for using it with Creatio via OAuth:…


Best regards,


Kate Karpik,

Thanks for the clarification :)

Regarding shared mailboxes using Oauth - can it be done also in 7.18.5 or do we need to upgrade to 8.0.3 minimum ?



P.S. Noticed the deprecation will be sooner than later (Oct 1st 2022 -


Dear Damien,


Thank you for your feedback.

Unfortunately, in order to add shared mailboxes that use OAuth authentication to Creatio you need a minimum version of 8.0.3


Best regards,
