Introduction

MailSuite Pro offers integration with various external services: Google, Facebook and Dropbox. For each of those services, integration is configured in the similar way - in a console offered by that service, you create an application and obtain a set of parameters used for authentication, and specify those parameters in MailSuite Pro admin interface section. Once that's done, users will be able to authenticate via those services and use access file storage where applicable.
