Office Add-In Deployment Manager : "Preview" as in "only selected customers can try it" or "everyone can try it but with no guaranty" ?
Actually the answer is a bit of both. The preview is currently limited to the following Admin users: - Those on Directory Sync (AAD<->AD) tenants - Those in US, CA, GB, IE, AU and NZ markets
We are working hard to test and localize the interface as soon as possible. The preview also has some fit and finish work that we need to complete before we can consider it done. We're working hard on that too!
