Question details

An organization needs to update a Microsoft AppSource listing after acquiring a company, but the original listing manager has left and their administrative credentials are no longer accessible.

Product: Microsoft AppSource
Device & OS: not provided
Scenario: A company acquisition has taken place, and the acquiring organization needs to gain administrative control over the acquired company's Microsoft AppSource profile.
Observed behavior: The acquiring organization is locked out of the AppSource listing management portal because the former listing manager's access cannot be transferred automatically without their login credentials.

Before you start

Prepare legal documentation proving the company acquisition and official corporate authorization letters to expedite the ownership verification process with Microsoft.

Solution 1Recommended

Contact Microsoft Partner Center or AppSource Support

The most reliable method to regain access is by submitting a formal support ticket to Microsoft so they can manually verify ownership and transfer administrative rights.

Because AppSource profile management involves corporate identity and security, Microsoft requires specialized verification when the original administrator is no longer available. This process cannot be completed through self-service portals.

Log into the support portal

Go to the Microsoft Partner Center or AppSource support portal and log in with your current corporate Microsoft account.

Create a new support request

Open a new support ticket under the account management or AppSource listing category.

Explain the acquisition scenario

Detail in the ticket that the company was acquired, the original listing manager has left, and you need to transfer administrative access to the acquiring company.

Provide legal verification

Submit the requested legal proof of acquisition and entity ownership when contacted by the Microsoft support agent to finalize the transfer.

Verification Timeline: The legal verification process may take several business days depending on the complexity of the acquisition documents.

Solution 2

Escalate via Dynamics 365 and AppSource Community

If you face delays with standard support channels, posting in official Microsoft communities can help escalate your issue to moderators and Microsoft employees.

Frequently Asked Questions

Can I bypass Microsoft support to change the AppSource listing owner?

No. If the original owner's account is completely inaccessible following an acquisition or employee departure, Microsoft must manually verify legal ownership before granting access to a new administrator.

What documents are typically required to prove a company acquisition to Microsoft?

You will generally need to provide official legal acquisition documents, updated corporate entity registration, and formal authorization letters on the acquiring company's letterhead.

How long does the AppSource listing transfer process take?

The timeline depends on how quickly Microsoft's support team can review the legal documentation. Once all verified proof is submitted, it typically takes a few business days to process the administrative transfer.
