My Outlook.com mailbox has hidden or corrupted server‑side inbox rules. ‘Create rule’ is greyed out. Please run an InboxRules purge/reset on my account.

Hi neil medic

I understand how frustrating this is when mailbox rules appear to be corrupted and the “Create rule” option is unavailable.

Since this is a public community forum, no one here has access to Outlook.com mailboxes and I cannot perform an InboxRules purge/reset or make account-level changes on your behalf.

Before try contacting support, please try this quick check:

• Sign in to Outlook.com via a web browser
• Go to “Settings” > “Mail” > “Rules”
• Check whether existing rules are visible and whether you can edit or delete them there.

If the issue persists and you believe the mailbox contains hidden or corrupted server-side rules, you'll need to contact Outlook.com Support so they can review the mailbox directly:

• Go to Contact Us - Microsoft Support 
• Select the product or service you're having issue with.
• Click Get Home Support
• Type a brief description of your issue in the search box.
• Click Get Help and select Contact Support below. 
• Go to the Products and services tab and choose the appropriate product.
• On the Category tab, choose the appropriate category or an alternative option.
• Go to Confirm.
• Look for and select "Chat with a support agent in your web browser" (during business hours) if available. Explain your situation clearly.

Feel free to share any updates at your convenience and thank you for your understanding.
