For anyone wanting to test Office 365 and associated technologies, you can easily spin up a free trial, without a credit card for evaluating and seeing what 365 has to offer.
To get started, head over to outlook.com and create a free account. In this example, i’m using the address trial-365-2021@outlook.com

After you have your outlook.com account, browse to the following portal.office.com link which is the standing offer for a 30 day free trial of Office 365 E3 that includes 25 licenses.

Go through the wizard and fill in your details. You’ll need a legitimate phone number to verify you are a person and not a bot. You’ll create your business identity and proceed to create an admin login.


As you can see, my trial has been created and a confirmation email sent to my test outlook.com email address.
Now, you can jump over to https://portal.office.com/AdminPortal/ and login with your trial admin account. From here, jump into licenses and you’ll see your 30 days of Office 365 E3, which includes fully routable mail to your <domain>.onmicrosoft.com address.

From time to time, Microsoft offer other trials that you can add to your existing subscription. For example, at the moment, you can add PowerBI Premium or Defender for Office 365 trials. From the admin portal, browse to Billing –> Purchase Services –> Search –> ‘Trial’ and see what is available.
Now that you have your trial, you can test Exchange Online, SharePoint Online, Yammer, Teams and OneDrive – not to mention Azure AD and all the identity features that come along with it.
Good luck with your 365 trial!
