Office 365 orders for a particular reseller fail with the following error:
Service Creation Failed: Parallels Operations Automation error #error_code #0, extype_id #1, module_id #Common, Internal error: APSC: The ambiguity of application instance resources has been detected...
The subscription in question is being provisioned through syndication instance, but the customer already has an Office 365 subscription provisioned through CSP instance.
It is unsupported scenario to have CSP and syndication Office 365 subscription on the same account. It is recommended to avoid providing customers with possibility to purchase CSP and syndication subscriptions at the same time.
