My apologies. I meant ADO-E303 is suspended.  Currently, I get the following message when I try to schedule an exam - "Exam AD0-E303 Adobe Campaign Classic Architect is temporarily suspended until further notice. Questions? Certif@adobe.com."

Any idea why it is suspended and when can we appear for the exam?

Thanks for the quick response, Jon.What I am trying to understand is what does multi-tenancy means in Campaign Classic. what are its impact on data partitioning, OOTB reports, templates etc. I have just started doing the research and trying to understand the pros and cons of multi-tenancy.I believe ...

Where can I get more information on Multi-tenancy in Campaign Classic? I am trying to find out how it works and it's limitations on data sharing, reports, templates etc.Additionally, is there any document on multi-phase implementation?
