- Product
- Microsoft Office 365
- Device & OS
- not provided
- Scenario
- Accessing the Microsoft 365 admin center dashboard to manage a newly created E5 trial account and cancel automatic renewal.
- Observed behavior
- The system displays an 'Account not found' error, locking the user out of the dashboard while the trial subscription and automatic renewal remain active in the backend.
Ensure you have the exact email address, phone number, credit card details, and the custom domain (e.g., .onmicrosoft.com) used during registration ready before contacting support.
Contact Microsoft Support via Admin Center
Use the Microsoft 365 Admin Center portal to create a service request and ask support to disable automatic renewal or restore access.
Even if your direct admin link fails, you can sometimes access the generic support portal to submit a ticket. The support team can manually verify your subscription status.
Navigate to portal.office.com in your web browser and attempt to sign in with your trial admin credentials.
Locate and select the 'Help and support' icon from the lower right side of the admin center dashboard.
Type a brief description explaining that you are receiving an 'Account not found' error on a new E5 trial.
Select 'Contact support' and complete the service request form with your accurate contact details.
Explicitly request the support agent to verify your subscription status and disable automatic renewal to avoid unexpected charges.

Contact Microsoft Customer Service by Phone
If you are completely locked out of the Admin Center and cannot submit a ticket, call Microsoft Support directly to cancel the subscription.

Frequently Asked Questions
Will I be charged if I can't log in to cancel my Office 365 E5 trial?
Yes, if automatic renewal was enabled during registration, your card may be charged when the 30-day trial ends, even if you experience an 'Account not found' error. You must contact Microsoft Billing Support to disable the renewal.
Why does my new Office 365 account say 'Account not found'?
This error can occur due to backend syncing delays, entering the incorrect tenant domain (e.g., missing the .onmicrosoft.com extension), or browser cache issues preventing proper authentication to the admin center.
Can I create a new trial account with the same email and card details to fix this?
While the system might allow you to register again, doing so can create duplicate tenant accounts or billing confusion. It is highly recommended to resolve the original account login issue with support before attempting to sign up again.
