Microsoft has recently moved to modern authentication (OAuth 2.0 token-based authorization). This has many security benefits and improvements that help mitigate security issues in the old basic authentication method. 

There are 3 simple steps you need to follow to move to the new Microsoft OAuth 2.0. 

This process should take about 20 seconds per Microsoft Outlook channel you have. Please make sure you follow this process for every Outlook channel that you have.

• Step 1: In the Receiving mode dropdown of Mailbox settings select Pull emails via Microsoft Outlook API

• Step 2: Click Connect Outlook to eDesk 

Below is a list of your Outlook channel(s). 

• Step 3: Follow the simple steps in Outlook to renew eDesk’s permissions.
