Deprecated: "none" as Single Sign-On option and Basic Authentication for Exchange Online

Hi, 

The following features will be deprecated, starting from version 3.20.0.

 

"none" as a Single Sign-On option

We're going to deprecate the "none" as a Single Sign-On option. Due to security concerns, please upgrade to the latest and safest option oAuth2. This can easily be done by following this article. As Microsoft is disabling Basic Authentication for Exchange Online as well, it's recommended to move to oAuth2 (for more information see next item).

Am I affected?

  • NOT using oAuth2 as Single Sign-On option.

Basic Authentication for Exchange Online

We're going to deprecate the Basic Authentication for Exchange Online. Microsoft has announced that they are going to disable Basic Authentication on October 13th 2020 for Exchange Online (EWS). In Workspace 365, we use EWS (Exchange Web Services) to fetch the mailbox of the signed-in user. 

  • When you have not configured OAuth2 as your Single Sign-On method, we use Basic Authentication for communication with Exchange. This means that after 13th of October, the communication between Workspace 365 and Exchange will stop to function (e.g. Email, Address book, To-Do etc)

Are you using OAuth2 and Integration Credentials to connect to Exchange Online?
If yes, then you are using Basic Authentication as well. Please make sure you can connect to Exchange Online via OAuth2 without Integration Credentials.

Am I affected?

  • Using Integration Credentials for the connection to Exchange Online.
  • NOT using OAuth2 as Single Sign-On option.
