Summary
This article explains how to access and use the Microsoft Exchange Admin Center to manage external email settings in a your CWU email account. These tools help ensure important messages are received while blocking unwanted or potentially harmful senders.
Using Microsoft Exchange Admin Center
Once you are logged into your MyCWU account on your computer, you can access the Microsoft Exchange Admin Center. The Exchange Admin Center includes tools to help manage specific email settings, such as blocking or allowing senders.
From here, you can:
- Follow this link to access your personal Exchange Admin account:
https://admin.exchange.microsoft.com/#/
- In the left-hand menu, click on Block and Allow.
- On the Block or Allow page, click Blocked senders. A panel will open on the right side of the screen where you can manage your blocked senders list.
- Click Add sender or domain to add an address to the block list.
- Select an entry and click Edit or Delete to update your list.

Select which sender you'd like to block or allow
While the Exchange Admin Center allows you to add domains to your list, this is not best practice. Please add only specific whole email addresses.
