I would like to see that the Alert notification for Private Office 365 Groups work the same way they do for Public Groups. We run into this issue as users create Private Office 365 Groups. There than wanted to setup Alert Notification under Files for Group members. It does not work. Change the Group to Public and you will get alerts.
Only work around right now is modifying the URL to https://testdomain.sharepoint.com/sites/testgroupyph/_layouts/15/people.aspx and adding the users manually to the permission group.

The Groups logo should be a bit smaller, also too much vertical space is taken up in the header. This space can be better used for displaying more documents.

Better Group Management. I think it would be useful if there were more options regarding group members permissions. You could create 'subgroups' of members in addition to "Owners", "Members", and "Visitors", where you could assign certain group members to these 'subgroups' and modify the permissions of this 'subgroup'.

Please enable the ability to @mention an O365 group from a Sharepoint page. This will allow the power of push notifications, on mobile devices, to reach an intended audience. It works great for individuals but cannot do it for groups. It will allow a News post to be directed to a target group, then with one click on the received notification, the News post will open in the mobile Sharepoint app.

We like to manage authorisation on Modern SharePoint sites and MS-Teams using AD Security Groups, however it is not possible to add an AD Security Group into an Office 365 Group.
Please add this option.

If the HiddenFromAddressListsEnabled is true for the Office 365 Group associated with the team site which is generated via Teams, the site logo can’t be changed properly in SharePoint currently.
We could change the site logo if we change the value of HiddenFromAddressListsEnabled to False. But we need to change the value with cmdlet and it makes the group be shown in GAL. So, it would be great if we could change the site logo for the team site which is generated through Teams by default.

SharePoint グループの復元機能
Restoring SharePoint groups

■Description(内容):
現在 SharePoint グループを削除してしまうと、復元することができないため、削除された SharePoint グループはゴミ箱等に移動し、一定期間内であれば復元が可能な機能の追加を要望します。

At present, if a SharePoint group is deleted, it’s not possible to restore it. Please change this so that deleted groups are moved to something like a Bin, where as long as it’s within a specific period they can be restored.

I have one share link with many users, I would like manage this user list for delete just one for exemple.
At the moment on Sharepoint Online, it possible delete just the link. So, it does again share.
This process isn't simple et heavy in time.

Enable Team owners to establish (in Teams) "push" only info channels (publish info, do not allow replies) along with conversation channels (where information can be shared and questions/replies added). Ideal for organizations using Teams to boost "news".

Teams で作成される Office 365 グループ サイトの管理を、SharePoint 管理センターのみではなく Teams 管理センターからも行えるように機能の拡充を希望します。
サイトの容量の指定などが、SharePoint 管理センターからのみでした操作できないので、Teams で作成されたグループ サイトは区別できるようにしてほしい
I would like the option to manage Office 365 Group Sites created through Teams not only through the SharePoint Admin Center, but also through the Teams Admin Center.
It’s not possible to set things such as site storage volumes etc via anything but the SharePoint Admin Center, so in the case of Group Sites created through Teams I would like to manage them through that Admin Center.

Trying to identify Groups vs Team is difficult, In AAD they both show as Groups. The ability to run a report of all Teams that created a group, all Groups that have a Team, all groups that do not ave a team would be nice. Even if this option is via powershell.

When creating a new Office 365 Group (or Team), allow the creator to enter a URL for the corresponding SharePoint site in addition to the Group Name. Using the Group or Team name creates a URL that is often unusable and may not meet desired naming standards.

"Group membership" appears to list members in random order making it difficult to locate members based on their name. Please list group members in alphabetical order and have separate sections for Owners and Members

SharePoint グループの "<サイト名> メンバー" グループへユーザーを追加できないよう動作の変更を希望します。
Option to prevent users from being added to “<site name> members” SharePoint groups

■Description(内容):
SharePoint グループの "<サイト名> メンバー" グループに含まれているユーザーは、該当グループに他のユーザーを追加することが可能です。
※ 該当ユーザーは、"<サイト名> 閲覧者" グループにはユーザーを追加できないことを確認しています。
勝手にユーザーを追加されると管理がしづらくなるため、該当グループに他のユーザーを追加できないよう動作の変更を希望します。

Users included in “<site name> members” SharePoint groups can add other members to this group.
* These users cannot add members to “<site name> viewers” groups.
It is difficult to manage groups when users can invite others of their own accord, so please add a way to prevent members of this group adding other users to it.

Currently, no matter what permission an external/Guest user has, the user is not able to view members from the SharePoint Teams/Group Site. The only thing they are showed is members 3 or 5 or 9....

But internal users can view members by clicking "members" from the top right corner of the site.

If there is a reason why it's been disabled for external users, Provide an article with an explanation.

In SPO, allow for viewing and saving a members calendar in the group calendar function. No option to add person(s) permanently to a calendar view/scope. Defeats the purpose of group calendars on a collaboration website.

GroupID について
About GroupIDs

■Description(内容):
SharePoint Online のコミュニケーションサイトを作成した際に、Owners グループが ID=3 と ID=4 で作成される時があります。
回覧が完了したアイテムの編集は Owners グループが GroupID=3 のみに制御をかけていたため、サイトにより ID=4 となると回覧完了した文書の編集を誰も行うことができなくなってしまう事象が発生してしまいました。
そのため、Owners グループの ID がどのサイトでも統一してほしいです。

When communication sites are created on SharePoint Online, there are times when the Owners group is created with ID=3 and ID=4.
We placed a restriction only on GroupID=3 groups to control editing of items that have finished being circulated, and as a result people in groups with ID=4 were rendered unable to edit these items.
Please make it so that the ID of Owners groups is always the same.
