We at Microsoft put our users’ satisfaction first. It is even more important for us in the Outlook Mail Apps team as we have two set of users, developers and consumers. To make sure that every single one of our users are able to communicate their feedback to us we are opening a UserVoice page at http://appsforoutlook.uservoice.com. Our UserVoice page helps us to ensure every developer’s voice is heard.
In addition to our UserVoice page, we are also monitoring the “office365-apps” tag on StackOverFlow to help you out in developing your apps.
Over the past few months we have enhanced our API set more and added Contextual Mail Apps to Outlook. We have more exciting features in the pipeline and your feedback is going to help us deliver the best experience with the best timing. Please provide us your feedback and wishes.
