Solution 1Recommended

Re-contact Microsoft Support with Previous Case Details

Open a new chat support request referencing your previously closed ticket to escalate the unresolved activation and storage issues.

Since the Community forums and Microsoft Support are separate entities, community specialists cannot manually reopen your ticket. You must initiate a new chat with the official support team and provide your previous case number so they can review the history of your unresolved issue.

Navigate to Microsoft Support

Go to the official Contact Microsoft Support webpage and click on the 'Get Help' button.

Initiate Support Request

Type a brief description of your issue in the search box, and then click the 'Contact Support' button located at the bottom of the page.

Select Product Category

Under 'Products and services', select 'Microsoft 365 and Office'. Under 'Category', choose 'Manage my subscription' or 'Billing and Account Profile questions'.

Request Chat Assistance

Choose the option to 'Chat with a support agent in your web browser'. Once connected, immediately provide the agent with your old case number, your product key, and any screenshots of the activation error.

Re-contact Microsoft Support with Previous Case Details

Information Required: Be prepared to tell the agent exactly where you purchased the product key and where you attempted to activate it, as this helps them identify the root cause of the error.

Frequently Asked Questions

Why was my Microsoft Support case closed before my issue was fixed?

Cases can sometimes be closed automatically due to system timeouts, a lack of response within a certain timeframe, or if an agent incorrectly marks the issue as resolved. Providing your previous case number when contacting them again helps them reopen the investigation seamlessly.

How do I find my previous Microsoft Support case number?

You can usually find your previous case numbers in the confirmation emails sent by Microsoft Support when you first opened the ticket, or by checking the support history section in your Microsoft account dashboard.

What should I do if my OneDrive storage still shows as full despite having an active Microsoft 365 subscription?

It can take up to 24 to 48 hours for storage limits to update across all servers after a purchase or renewal. If the issue persists beyond this timeframe, try signing out and signing back into your account, or ask the support agent to manually refresh your account quota.
