Prepare the information support needs before contacting Lizenzpro about an order, entitlement, or activation issue.
Order questions
Include the order number, exact product title, purchase email, and a concise description of the issue. Never send a full product key, password, recovery code, or complete payment details.
License and activation questions
State the installed edition, operating-system version, activation method, and exact error code. A product key and a license are different concepts; support must first verify that the installed product matches the purchased entitlement.
Invalid, used, or region-mismatched entitlement
Do not repeatedly retry an entitlement. Record the message and contact support so the supplier and provisioning path can be checked.
Hardware change or reinstall
Reassignment and reinstall rights depend on the actual license channel and applicable terms. They cannot be inferred from successful activation alone.
Business subscriptions
Provide the organization name, Microsoft tenant domain, user count, market, selected plan, term, billing cycle, and Teams requirement. Never create a new tenant when an existing tenant should be used without confirming the migration impact.
