Office 365 Groups are best thought of as the combination of a few existing features and products, all bundled up for ease of use by just a few employees, an entire department, or even colleagues in multiple departments working on a project:
- Distribution Groups and Shared Mailbox — Called Conversations, each Office 365 Group has an an email address associated with it that, when emailed, creates a conversation that's distributed to all other members of that Group, as well as kept in the Group inbox for future reference.
- OneDrive — Each Group has its own OneDrive, which allows you to share files with your colleagues from a space owned by the group, not by an individual, all without the location-based confines of local file server (yes, this means you can keep your files in a place you can get to from just about anywhere!). All members have read and write capabilities, and these files are easily accessible from any mobile device. Files can also be synchronized to your desktop for offline access (a la Dropbox).
- Shared Calendar — Each Group also has its own calendar, viewable and modifiable by any Member of the Group.
- OneNote — Each Group has its own OneNote notebook. This notebook is shared across the group and synchronized in near-realtime, allowing members to keep organized notes easily viewable by all.
- Planner — Task management for teams. Make a plan, assign tasks to one or more team members, and group them into buckets. Even supports email reminders so you'll never miss a beat.
- Teams — Microsoft's group messaging system is built into Office 365 Groups, so you can avoid the inbox and message directly with individuals or the entire Group instantaneously (even on mobile devices). For more information on using Teams at Bedrock Manufacturing, please see this article.
While these various resources are all accessible via web browser, some prefer to use desktop apps or mobile devices (Microsoft Outlook for Windows, or MobileMail on Apple iPhone, for example). Thankfully, the various aspects of Groups are very accessible:
- Conversations — Any email application; Outlook Web Access; Office Groups for Mobile (Android and/or Apple iOS)
- Files — Any browser; OneDrive for Windows; OneDrive for Macintosh; OneDrive for Mobile; SharePoint for Mobile
- Calendar — Any browser; Outlook for Windows; Outlook for Macintosh; Office Groups for Mobile
- Notebook — Any browser; OneNote for Windows; OneNote for Macintosh; OneNote for Mobile
- Planner — Any browser; Planner for Mobile
- Teams — Any browser; Teams for Windows; Teams for Macintosh; Teams for Mobile
Groups can be made for various purposes: to serve as the general collaborative space for the general needs of an individual department, for a specific project, or even for a subset of a department that needs a little added security.
Groups can be private or public, so you have the option to lock down data that you wish to keep close to the vest in one Group, but provide another Group to the public (entire Bedrock organization) that contains information you feel suitable for public consumption.
What about outside users?
From Microsoft: "Guest access in Office 365 Groups enables you and your team to collaborate with people from outside your organization by granting them access to group conversations, files, calendar invitations, and the group notebook. Access can be granted to a guest—including partners, vendors, suppliers, or consultants—by any group owner."
As well, Groups can be configured to allow just about anybody (even without an account) to participate in file sharing.
