Currently in order to be able to reply a message using the group email address instead of the user's, several steps have to be performed:

• Grant access to every user in the group using Powershell (Add-RecipientPermission -Identity $recp.Name -Trustee $user -AccessRights SendAs)

And then the users have to do, everytime, for every email they reply:
- Dettach the reply window to open a new one with full capabilities
- Click on 'From:' button
- Select the group email address.

This scenario should be enhanced to:
- Enable SendAs rights to the group so users inherit the behaviour of the group (and a parameter on the web to enable it)
- Allow choose the reply address in the 'conversation window' in Outlook 2016/Web (or at least remember the last chosen option)

We're trying to change the default smtp address of a Unified Group. We would expect our Exchange admins to be able to manage this. When following this documentation, https://technet.microsoft.com/en-us/library/mt432940(v=exchg.160).aspx, we discover that the admin must be in the following role groups:

Organization Management
Recipient Management
Id Admin
Service_account

After this failed, we took the case to Office 365 support. There they instructed us that this must be done by someone with Global Administrator role. The only documentation for this reality is located here: https://support.office.com/en-us/article/Create-an-Office-365-group-in-the-admin-center-74a1ef8b-3844-4d08-9980-9f8f7a36000f

This article makes the following general statement. "While users can create an Office 365 group from Outlook or other apps, as the global admin, you may need to create or delete groups, add or remove members, and customize how they work."

So far this is the only documentation that can be provided that backs up the claim that only Global Administrators can change the primary SMTP address.

When asking support to feed this feedback to the product team, they directed me to UserVoice.

Ability to toggle External Sharing for an Office365 Group (and perhaps based on Classification)
With Groups you can set Sharing with External from a Tenant perspective but there are no direct end-user controls to allow or disallow external sharing per group.
Owners should be able to enable/disable the ability for the group to be shared with external.
Building upon this though;
Recently the Classification feature has been introduced to Groups and my second recommendation or feature wish would be to link the ability to share a Group with external based on the classification.
E.g. :
- If classification is: "Internal" -> No External sharing possible.
- if classification is: "Public" -> External Sharing is possible.

As a consultancy that makes a living "selling" O365 to our customers, we are currently "dogfooding" groups in our own organization. One thing that people have a hard time figuring out is the concept "shared with us".
I tell people i shared the file to the group, and they get back with "it's not there", since they did not look inside the "shared with us" view.
I guess the concept "sharing" is vague, since this could mean I shared it from my own OneDrive or shared it to the group by adding the file to "Files" in the group.
Hence it would be nice to have an "All files" view, that contained both files that belongs to the group and files shared with the group, as it really does not matter for the end user if it is one or the other. In stead one could add a column indicating that a file is shared from "external" storage.
