I have a parent and a child business unit, the parent BU is not the top-level BU but also a child of the top-level. Like this:
Top-level BU |__ Child BU A |__ Child BU B
The microsite lives in
Child BU A, and the email is being sent from
Child BU B. Using
MicrositeURL() I am getting the error The page you have requested is unavailable!.
The documentation here states that child BU's can access microsites from the top-level BU but does not specify if any other parent BUs can be used. https://code.exacttarget.com/content-scripting/ampscript/sites/MicrositeURL.html
Does anyone know if this is possible? Because of client data restrictions we cannot have the microsite living at the top-level.
