Outlook 2016 allows access to Conversations, Calendar, Files and Notebook. However, it's not possible to view a Group Calendar in the Calendar pane, which means that you cannot display side-by-side calendar views with any other Outlook/SharePoint calendar. It'd be great if this feature could be added!

Right now, when you create a calendar appointment, the group itself is automatically invited, and so the calendar functions like a distribution list, inviting all the members of the Group.

We would like the calendar to have the ability to act more like a separate calendar, or a teamsite calendar. The overlay function would be powerful if we could use the calendar for ... say a leave/Out of office calendar and overlay it over our own calendar.

When creating groups, or after the fact with a PowerShell command, all the ability to set a hide=True attribute so that the group is not visible when viewing all. Several other elements such as distribution lists and security groups can be hidden so why not allow the ability to hide Groups. This will allow groups to exist that are truly "private". This would be very helpful for groups that need a bit more privacy in order to operate using the Groups functionality beyond the invite only capability.

It would be nice if the Tasks created in the planner using O365 groups would appear under the 'task' section of outlook.

We're in a school environment and teachers are creating Office 365 groups and some of them shared information about students in them.

Although we've instructed them to change the accesstype to private, there are still groups being made which remain public.

Be able to Nest Groups like Distribution Groups. I decided to convert a lot of our team DGs to O365 groups without realizing I wouldn't be able to nest them

There should be an option to convert a shared mailbox to an office 365 group especially since the Office 365 Group is the newer better version of the Shared mailbox and there is no way to convert.

Email alias does not support many characters that are common in email addresses (e.g. "dot"), and cannot be changed after initial configuration. Additionally, alias creates an email address using the tenancy's "default" domain--doesn't allow you to select a domain if a tenancy has multiple domains. Finally, can't be changed after creation. All three of these are painful!

When you rename an Office 365 group, only the display name changes. It is not possible to edit the email address or the name of the OneDrive associated to the group. This is confusing, especially for OneDrive.

It should be possible to change all names associated with the group when renaming.

Also provide "drag and drop" functionality within Outlook. Sometimes a conversion will take place outside of the Group, but that conversation may be important to the Group. Have the function to "drag and drop" an email into the Group Inbox would be a great tool.

(This is already available if the Group Shared Mailbox is added to Outlook, but a few design changes will make this feature for user-friendly and available in the desktop client.)

Today when you create a group, it is created under the "/sites" managed path. Please change this so we always can have complete governance over the /sites-path. So when we want to create new site-collections you won't get URL-conflicts.

Love the ability to add task to a group with Planner but please have task that have an expiration date automatically add themselves to the Group calendar and the Assigned resource's calendar automatically.

Please add a Groups button in the App Launcher. I thought this was a planned release.

I understand the reasoning behind Groups and modern teams and using Delve. However, my clients don't care and want a button. Thanks

Currently unsubscribing from a group does not actually stop emails from being sent to your personal inbox.

The behaviour should be: If a user unsubscribes from a group, they are unsubscribed. Yes, it seems obvious, however Microsoft acknowledged the intended behaviour for unsubscribing is to still send emails to the unsubscribed user's inbox.

For more context see the forum thread.

We need to be able to create a group for an already existing team site, OR when creating a group, be able to select an already existing team site as the group site.

When contributing to a Group. Enable feature to move documents directly from Onedrive to a specific map within a Group. (now done by downloading / uploading). But documents are already in Office 365

As soon as someone creates a private group, this should by default be hidden from GAL.

There are PowerShell CmdLets which allow administrators to hide/show the groups from the GAL. However this is a post-facto activity. With many users and groups this is very tedious and many times we don't even come know that a group has been created by someone somwhere.

Show groups in the Outlook client, so users dont have to go to OWA to see there groups and whats going on in them.
