How to Configure Microsoft Exchange Online Email Import Using EWS

Exchange Integration now supports the Exchange Web Services (EWS) protocol for connecting to Exchange Online. This update ensures that Exchange Integration continues to work seamlessly with Exchange Online while also simplifying the setup process. To take advantage of this enhancement, you’ll need to configure a new Exchange Integration source. Any new actions created using this source will automatically use EWS.

By switching to EWS, the configuration process becomes more streamlined, removing the need for a dedicated service account and eliminating the extra step of updating service account permissions when new users with mailboxes are added.

Requirement

You must have a Microsoft 365 account with administrator privileges.

Note that you will no longer need a service account to set up an Exchange Online source.

Add a New Exchange Online Source

These instructions will set up a new Exchange Online source using EWS.

Log into the Barracuda Cloud Archiving Service as the admin, and go to Mail Sources > Exchange online.
Click Start new action. Click Email import.
Click Add new source.
A new pop-up window prompts you to enter your Microsoft 365 administrator account login information from which Exchange Integration will process mail.
Click Accept to authorize the Barracuda Cloud Archiving Service application to access your details. Check the Consent on behalf of your organization box.
You are redirected back to the Select source page. You should now see the new source in the list. Select the new source and click Next.
In the Configure action page, select All users from the drop-down menu, and specify the desired Date setting. Click Next.
Verify the configuration settings in the View summary page, and then click Finish to add the Email Import to the Scheduled Actions table.

Note that nightly email sync for Exchange Online is no longer supported. Click the 3 dots next to the action and select Run now.

Edit an Exchange Online Source

You can revoke access to the Barracuda Cloud Archiving Service application by removing it from your organization's Enterprise Applications in Microsoft's Admin interface. To restore access, you can add a new source and authorize the application again. If you have not removed the Exchange Online source on the Exchange Integration page, you can edit the source and a new configuration name. This takes you back to Microsoft's site to log in and consent to the required application permissions again.

Log into the Barracuda Message Archiver as the admin, and go to Mail Sources > Exchange integration.
Click Start new action. In the Select action page, click Email import.
In the Select Source page, click the Edit icon next to the source you want to change.
If needed, change the configuration name and click Save.
