If your organization uses Office 365, we recommend that you use Nylas's Suggested Office 365 settings and allow EAS Connections. 

Due to the way Nylas syncs mail with Microsoft accounts (through Exchange ActiveSync) it's possible you may have trouble with the sync if your organization has Intune or another Master Data Management system in place. This may include self-hosted Exchange servers as well as Microsoft's Office 365.

Troubleshooting "Admin Approval Needed"

When setting up Messaging, you may get the following error when trying to authenticate with Office 365. This happens if your organization's Office 365 Admins have enabled advanced security settings within Azure Active Directory (Microsoft's cloud-based application access management) to restrict access to third party applications like SeekOut at an Org level.


A Global Administrator with access to Azure Active Directory can configure these settings to allow integration with SeekOut.

Step 1: Log into with Global Admin credentials to access the Azure Active Directory admin Center.

Step 2: On a separate tab, navigate to the following link:

Step 3: Clicking on the link will direct to the following window. Since the admin is already logged in from Step 1, they will not be prompted to login again.

The admin will be authorizing on behalf of all the SeekOut users in their organization. 

Clicking Accept will redirect them to a Nylas page. That can be ignored.

Step 4: Admin should confirm they see the SeekOut Messaging app in Azure Active Directory, under Enterprise Applications:

Step 5: Once the admin has authorized on behalf of their org's users, the users only need to authenticate and should not see the admin approval message.
