Plan for Office 365 Groups when creating teams in Microsoft Teams
When considering the use of Office 365 Groups or when creating teams, consider what the team will be used for, who should have access, and what outcome the team will expect to achieve. Pay special attention to the number of channels you create as people can quickly become overrun by content spread too thin (across too many channels).
There are two scenarios that warrant some discussion around planning of Office 365 Groups and their impact on (or by) Microsoft Teams:
First, since customers could have existing investments in Groups, we currently support both Public and Private groups of less than 5000 members. As mentioned previously, you want to manage the membership of people to a team using the Teams client rather than the Office 365 admin web console. Given this scenario, if people are used to threaded conversations in Office 365 Groups, it is worthwhile noting that a Groups conversation is essentially email and not the same as a chat message in a Teams channel. Educate your people about this difference and suggest they adopt the more flexible chat message format in Teams versus emailing the Group using Outlook or OWA.
Second, for customers who don’t have existing Groups defined in Office 365, you can either create them using the Office 365 admin portal, the Teams web, or desktop clients. As mentioned previously, manage all future membership to the Office 365 Group using the Teams client. Since membership to a team is also defining membership to Office 365 Groups, you should prepare people for this change.
Teams respects Office 365 Groups naming policy (in private preview)
Any Office 365 Groups naming policy that has been set by your admin will be applied in Teams when users create or edit team names. This includes things like mandatory prefixes or suffixes and excluding banned words.
This feature is in private preview, which means that if you're not part of this preview, Teams doesn't yet adhere to this Office 365 Groups naming policy.
