[27/08/2015] Please check https://aka.ms/office365groups for the latest official messaging and roadmap

To support a project, you can easily create a new Group and invite colleagues. You can also search for and join existing Groups, which are open by default, to see all discussions, milestones and files and get up to speed quickly.  Of course, you can create private Groups as well for sensitive projects and content.

Office 365 Groups are only available to specific plans

if your tenant has access to Groups, you should find a "Groups" entry in the left-hand resource tree displayed by OWA.

  • E1-E4
  • A1-A4
  • G1-G4
  • Business Essentials and Business Premium plans, Business, Small Business Premium and Midsize Business plans
  • Kiosk plan

Frequently asked questions

Q. Which Office 365 plans include Groups?
A. Groups is a feature that is available in Outlook Web App email and calendar and OneDrive for Business, and will be rolled out to all customers that have an Exchange Online or Office 365 commercial subscription, both new and existing. Eligible Office 365 plans include the Office 365 Enterprise E1–E4 subscription plans (including the corresponding A2–A4 and G1–G4 plans for Academic and Government customers, respectively), Office 365 Business Essentials and Business Premium plans, Office 365 Small Business, Small Business Premium and Midsize Business plans and Office 365 Kiosk plan.

Q. Is there a limit on the number of groups?
A. Groups with more than a 1000 members are supported, but group users may notice that accessing group conversations and the group calendar can take a long time.

Q. Where are the documents stored?
A. https://support.office.com/en-us/article/SharePoint-Online-and-OneDrive-for-Business-software-boundaries-and-limits-8f34ff47-b749-408b-abc0-b605e1f6d498?ui=en-US&rs=en-US&ad=US

A special form of Exchange mailbox provides the physical embodiment of a group. The mailbox is used to store group content up to a maximum of 50GB, including posts, messages, and calendar entries. The mailbox is linked with a document library that is apparently created within OneDrive for Business but really is a document library in a SharePoint site with some special UI to make it seem like it's OneDrive.

Max storage is 1TB. The storage for Groups is not based on OneDrive for Business, but rather it is an associated SharePoint Online document library, which has the following characteristics:

    1. Up to 1TB storage capacity
    2. Ability to upload files up to 2GB in size
    3. Uses the new usage-based storage model (space allocated as needed)
    4. Groups storage WILL count to the used space in the tenant. Please check also the Recycle Bin of groups

The document library is intended to provide storage for any other type of content shared within the group.
The properties of the group mailbox indicate to Exchange that its membership can be used for routing purposes.
Mail sent to the group will be delivered to all members. As such, you can think of a Group as being like an Exchange distribution group with storage (the mailbox).

Q. Are groups public or private?
A. Groups are either public or private.You select the group type when the group is first create and cannot (for now at least) change a group from public to private or vice versa afterwards. As the type implies, anyone can join a public group, so this is the best type of group for topics such as company-wide information, best restaurants in an area, and so on.

  • Users don’t have to join a group or be added by an administrator before they can contribute or view group contents as they can always email the group to start a new conversation or contribute to an existing debate.
  • Access to the content held in a private group is restricted to its membership.
  • The user who creates a group is automatically added as a group administrator.
  • Users who wish to join a private group can send a request to the administrators to join and the request must be approved before they can access the group.
  • Even though you might assume that someone who is not a member of a private group cannot post to it, that's not actually the case.
  • Anyone who belongs to a tenant can send email to a private group and that email will show up as a post in the conversations view.
  • A group can be changed from private to public, http://fasttrack.microsoft.com/roadmap#R-45211 

This is not a bug!
There are two scenarios when it is desirable for non-members to be able to post to a private group.

First, it might be a good thing for non-members to make a contribution to a group that's used for problem reporting. In this scenario, the actual members of the group are responsible for processing problems but anyone should be able to contribute.

Second, it might be a good thing for a group member to invite external parties to contribute to a conversation, perhaps to provide feedback to a project plan or a similar discussion. They can do this by asking the non-member to send email to the group.

Q. Is there any way to enable external users that do not have an O365 account to join an O365 group?
A. It’s on our roadmap as well as many other items: http://fasttrack.microsoft.com/roadmap#I-35213

Q. Is there a way to archive a group?
A. 
To preserve the content on an Office 365 group SharePoint site or OneDrive for Business site, create a preservation policy in the Security and Compliance Center. To place an Office 365 group mailbox on hold, create an In-Place Hold in the Exchange admin center.

Q. Is it possible (and if so, how) to share a document  in a group to external users?
A. 
It’s on our roadmap as well as many other items: http://fasttrack.microsoft.com/roadmap#I-35213

Q. In my tenant some user are seeing ‘Discover’ option under Groups & some are seeing ‘Browse’. I have checked o different browsers but the same thing is happening. Do you know why that is happening? Is there any way that I can hide an Office 365 group for certain set of users. As whomsoever clicks on browse or discover sees all the groups in OWA. I want to hide the private group for my students in the OWA.
A. 
We’re rolling out the discover feature – which replaces “browse”. In either case, users can see all groups (private or public), though they cannot see content in groups they aren’t members of. If you want to hide a group from the GAL, you can use powershell, but this won’t hide the group in other workloads (e.g. SharePoint). We’re working on “secret” groups to resolve this issue in the future, but I don’t have a date to share. More information: http://answers.microsoft.com/en-us/msoffice/forum/msoffice_o365admin-mso_manage/hide-office-365-groups/3b71a957-75ff-4e83-b1d8-0cada193df20?auth=1

Q. Is there a method to allow non-members to view the calendar of a public Office 365 group via Outlook 2016? I can see that this definitely works via OWA, but am unable to find a way to do it in Outlook?
A.If a group is public, a user can navigate to the group’s calendar in OWA.

Q. Is there any way to export the calendar in a group? I want to delete a group but keep the calendar
A.
Not directly. You can search your own calendar for the items that were sent to a given group and act on them.

Q. Is there an iOS app currently that performs the ability to sync Office 365 groups files?
A.
You can use your in your iOS device the sites button in the OneDrive app to browse into a group and take the file offline using the parachute app.

    @Hal This is not allowed at this time but we are actively working on enabling the scenario.  Adding non 0365 users or users from another domain to a unified group.

    1. Deniz Uysal says:

      Hi Hong, Did you find a solution for archiving a group? I am interested in this as well. I was hoping to build a workflow to copy the files from the Group to an Archive SharePoint site we have however I am unable to access the Group when I’m building the workflow.

    2. To preserve the content on an Office 365 group SharePoint site or OneDrive for Business site, create a preservation policy in the Security and Compliance Center.

        Tom. Any idea when this might come through? I’ve seen this sit there for a year now – any kind of rough, general idea when we might see it? Thanks. Ben

  12. Guy Horn says:

    Is the group included in the ad-connect synchronization so I can manage it from my on-premises ADDS?

  13. pam hindman says:

    Is there a way to receive notification in the “main Inbox” that a message is waiting in your “group(s)” inbox

  14. Milos says:

    Is there any way that user on premise (hybrid environment) add themselves to unified group. I know that users on premise can be added to a O365 group if they are on same domain, and they can easily unsubscribe from that group via unsubscribe button on email they recived. But my question is, can they add/remove themselves to a O365 group (through owa or some other way)?

  15. Sandy Boyd says:

    Is there a way to turn off the ability to create “Public” groups or allow only certain users the ability to create them?

  16. Barry Fox says:

    Is there a maximum number of members that a group can hold?

  17. Vicky says:

    I have enabled groups and email address policies for a Group. Now when i create a new Office 365 group from admin portal i do not see any groups domains in the menu.

    The users can create the groups fine but the admin cannot.

  18. Fred Ottenhof says:

    To enable Role Based Access Control in our organization I can create Office365 Groups for roles, and make users member of those groups. I now want to create other Office365 Groups for e.g. Projects in which such roles/ groups collaborate.
    I can not discover how to make other Office365 groups member of a new Office365 Group: that can only done with users.
    Am I walking on a sound track ? Are there better facilities for RBAC + Groups ?

  19. Elango Panchatcharam says:

    Hi Tom,

    I have a doubt do we have new GROUP mailbox type in office 365, if yes how this mailbox will be created and what all are the prereq we need. we are a office dedicated customer ANSI-2013.

  20. Dan M says:

    We mainly use the SharePoint (OneDrive Skinned) feature of the Groups we love that it now syncs to the OneDrive client on the local machine in the latest preview. We are starting to get close to our 1TB Limit. How do we go about buying more space for our groups we really need to buy another 9TB’s of data?

  21. JO says:

    Is there a way to allow group creation only to specific users within the organization?

  22. Amanda says:

    What documents types are supported in Groups? Can you upload videos/audio files?

  23. Gitte Hejselbak says:

    Just launched a pilot and it would be great to learn how it has been received. So – would it be possible to get usage statistics for a group, just ot get some facts and not “ask around”

  24. Nikhil says:

    Experts,
    Is there any limit on concurrent number of group conversation that can happen at one time. I means is there a hard limit where multiple group chats would be a threshold for office 365.

  25. Derek says:

    Is there any way to set the permissions of guests to Read for Office Group site libraries?
    This to disable the functionality of creating pages.

  26. HSmith says:

    I know you said you can archive a group, but can you archive conversations within a Group?

  27. Scott Stinton says:

    Is there a way to make the Site for an O365 Group public, the all other parts of the Group private?

    1. I’m not aware of such an option, at this moment you have the option to make the entire group public or private.

  28. Jamie Dupee says:

    What is the max number of groups that you can add to an organisation or domain?

    1. The default maximum number of groups that an Office 365 organization can have is currently 500,000.

  29. Jeris says:

    I am an IT support staff and we have recently implemented Group Sites via Planner. I have 1 member of a Group (There are 5 members) that every Conversation created within the Group Site is delivered to her Deleted Items folder. She is using Office 2013. I’ve checked her Rules in both Outlook 2013 and Office 365 Mail, marked the message as Save and to always allow. Nothing is working. Any tips? Thank you!

    1. This is an interesting scenario, I would recommend to post it on answers.microsoft.com under Office. If the problem is not resolved in time, I recommend you to seek the assistance of our Office 365 Support.

  30. Luis Marques says:

    Is there a way to export the Exchange Mailbox? We pretend do delete some Groups, but move the information to new groups or pst files.
