K2 integrates with Microsoft Exchange Online using Microsoft’s APIs. As Microsoft makes changes, we will update our integrations to ensure your solutions continue to function properly.

Microsoft has announced the retirement of the ApplicationImpersonation Role Based Access Control (RBAC) role in Exchange Online. Beginning in May 2024, new customers can no longer use this role, and in February 2025, the role and feature set will be removed from Exchange Online.

Edited 19 April 2024: K2 does not automatically add this role on configuration, so you may not be impacted by Microsoft’s change. This retirement will impact on-premises customers if the ApplicationImpersonation role was added to the account used to log in to EWS. If so, apply the fix pack listed below and then remove the ApplicationImpersonation role. 

This retirement will impact K2 Cloud and K2 Five / Nintex Automation environments which connect to Microsoft Exchange Online.

The fix and steps documented to use lesser Exchange Online permissions address the following features:

• Task Notification Emails
• Workflow Mail Events
• Escalation Emails
• SmartForms Email Rule Actions
• SmartActions

In addition, K2 can integrate with Microsoft Exchange to do other operations, such as creating meetings or tasks, and creating mailboxes. These items are available for Microsoft Exchange on-premises versions only.
