Litify Inbox: Switching to Microsoft 365 OAuth Impersonation

Microsoft has stated that they will be disabling basic authentication (login/password) for ALL Office 365 users by the end of 2021. With Revenue Grid, we’ve determined that this change may have an impact on your Litify Inbox experience. This article will provide you with some insight into what this means, and steps that your firm can use to avoid any negative impact from this change. 

This change applies only to Firms that use the Microsoft Exchange basic authorization (EWS API) - Impersonated logon mailbox access type with Litify Inbox. To determine which mailbox access type your Firm uses please refer to the Litify Inbox Admin Panel. 


Access to the Litify Inbox Admin Panel and to the Exchange Admin Center.
