Outlook add-ins enable users in your business the ability to access their favorite apps right in email and get more done, faster. As more add-ins are included to help users be more productive, the goal is to ensure that you have the tools to quickly and easily deploy add-ins. Last year, this feature was announced for availability of Centralized Deployment for Word, Excel and PowerPoint add-ins.
Starting February 26 through end of March, Centralized Deployment support for Outlook add-ins will begin rolling out.
With this feature, you can now deploy Outlook add-ins to individual users, groups and company wide easily within Office 365 Admin Center. Centralized Deployment supports both AppSource and Office Store add-ins, as well as custom internal add-ins. It will work for business versions Office 365 across Outlook on the web, Outlook 2013 and Outlook 2016 for Windows, Outlook 2016 for Mac and Outlook for iOS and Android. This feature is off-by-default so you can provide the right visibility for add-ins by either enabling them for everyone in your organization, or by giving end users the option to enable or disable them.
