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'.

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.

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.

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.

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.

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.

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.

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.

SharePoint サイトのプライバシーの設定をプライベートで作成したがサイトの作成後ユーザーによりパブリックサイトに変更されてしまった。
だれがいつ変更したか確認出来るログのアクティビティの追加を要望します。

The privacy setting of the SharePoint site was created privately, but after the site was created, the user changed it to a public site.
I'd like to add a log activity that shows who changed when.

Hello - I'd love to see the sharepoint home page launched as the home page within teams!

I would like you to fix the behavior that we can’t access the Office 365 group calendar from the SharePoint Online home page when browsing the site from mobile devices and tapping the calendar link. The calendar link will be created if you add a group calendar in the SPO site. The prompt box appears to force me signing-in. Even if I would sign-in, I cannot access a group calendar.
