Office 365 groups - Admin help

Getting things done at work or school means sharing information and collaborating with others. But working together is complicated when different apps are used for email, instant messaging, scheduling, storing documents, authoring, and so on. Office 365 Groups brings collaboration tools together so users can easily connect with the colleagues, information, and applications they need to do more.

As the admin for an Office 365 organization, you don't have to be the a group creator, owner, or member to manage Office 365 Groups. You still can create and delete groups, as well as control other settings on Office 365 groups.

Yammer now integrates with Office 365 Groups! See Yammer groups are now Office 365 Groups for details!

Office 365 groups help and how-to for admins

We're constantly making improvements to Office 365 groups. Here's a few things we've added in the last few months.

Group naming policies Group naming policies allows you to control how group names and email aliases appear in your organizations directory, and how they appear to users. You can require a specific prefix or suffix be added to the name for a distribution group when it's created. Group naming policies also lets you block specific words from being used in the group name. This helps you minimize the use of inappropriate words in group names. If your company requires that group naming policies be turned on, you must complete this relatively complex task using Exchange remote PowerShell. You can set your Office 365 groups naming policy by using the distribution group naming policy. Connect to Exchange Online and use remote PowerShell to turn on group naming policy. For the steps on setting your group naming policies, check out, Connect to Exchange Online using remote PowerShell and Create a Distribution Group Naming Policy.

Compliance and protection features in groups You can now perform an eDiscovery in-place hold on a group’s mailbox using Exchange Admin Center and on group files using the Office 365 Compliance Center. To get started, read Security and compliance for Exchange Online. Check out In-Place eDiscoveryYou can search an Office 365 group mailbox using either In-Place eDiscovery in the Exchange admin center or Compliance Search in the Security & Compliance Center.
