Hi T Mauz,
Thank you for reaching out to us on the Microsoft Q&A forum.
It seems you are having a problem in Configure your SaaS account.
Here is the process from Microsoft for SaaS subscription and configuration: -
When you select Subscribe, you see the following message: Your SaaS subscription is in progress. This process takes a few minutes. Don't close the window until it's finished. to configure the SaaS account, forward this email to the relevant person.
To complete the process and start using the SaaS offer, you're required to configure your subscription. In the SaaS offer in the online store, select Configure account now or in the email, select Configure now. You're redirected to the publisher's website. Billing starts after your account is configured on the publisher's website.
Important (If you don't complete the configuration process within 30 days, the SaaS subscription is automatically deleted.)
You can check your subscription status by selecting Notifications (bell).
