Add "People with Existing Access" to the Default Link Types under SharePoint Admin Center's sharing options.

Provide a link-check service on all sites, so Site Owners can limit the amount of broken links across their sites. Applies to SharePoint Online and SharePoint Server.

An option should be added to the "FILES" tab (when a document is selected) to unlock a document that "is locked for exclusive use by [user]"

As advised by O365 support, currently the only workaround is to download a copy and re-upload.

It's very useful for creating team dashboards. (Office365 Group Site)

Delve アプリで日本語のファイル名を検索できるようにしてほしい。
Please make Japanese filenames searchable on Delve app

■Description(内容)：
現在、iOS に Delve アプリをインストールして日本語名で検索をすると検索結果が何も表示されません。

英語のファイルであれば検索が可能です。
日本語のファイル名でも検索が可能となるように機能の実装を希望します

Currently nothing will be displayed in the search results if Delve app is installed on iOS and used to search using names in Japanese.

English files can be searched.
We hope that a Japanese file search feature can be implemented.

Recently we had an issue that we wanted the users to add tasks to the timeline. They couldn’t, because they hadn’t the “manage lists” permissions.
We don’t want them to add views, columns or new lists, they just need to add a Task to the Timeline.
Could you please change this?

Provide full support for IIS bindings - i.e. include SSL and IP Address + SNI options. It is slightly ridiculous that these settings must be managed outside of SharePoint and influence the logic of web application creation. Bring web app creation up to date with the versions of IIS SharePoint is running on.

Remove the alert notification for the internal/temp file "VerifyPerm(GUID)" from being sent when alerts exist in both document libraries (source and destination) and you use the ribbon "move to" feature.

Two emails are generated as expected, one for the file getting created in destination, and one for it getting deleted in source. However the issue occurs once this is done, a second email will be sent out with the title: "VerifyPerm(GUID)" for a temporary (non exposed) file which gets generated to check the permissions in the destination location. This is unesesary. Please remove this secondary message.

Can you allow more than 10 calendar overlay in SharePoint to integrate on 1 master calendar?

Stop using internal names in the background when referencing site columns in formulas. If the display name of a referenced site column is different from the internal name and it contains spaces, the formula will use the internal name when added to a list/library causing an error. When the calculated column is published from the CTHUB it also breaks the formula as the referenced column doesn't exist wit the same name on other site collections.

モダンサイトのサイドリンクバーの表示をトップバーの位置に表示させる
Display the side link bar at top bar position for Modern sites

We strongly hope that the side link bar in Modern sites can be displayed at the top bar position just like the communication site. Considering the design of the site display, it will be very useful if there is such a feature.

アイテムのアップロードのみが可能なアクセス権を付与できるように要望します。
Make it so that access permissions that only allows for uploading can be created

■Description(内容):
[投稿] 権限を付与することでアイテムのアップロードが可能とはなるが、同時にアイテムの編集および削除も可能となるため、[アイテムの編集] および [アイテムの削除] のアクセス権を外し権限を作成すると、アップロードは可能となるがエラー メッセージが表示されるため改善を希望します。
Uploading of items is made possible by granting "Post" permissions, but at the same time editing and deletion of items becomes possible as well. We can make permissions that exclude the "Modify item" and "Delete item" access permissions, but an error message appears when uploading items. Thus we hope that new permissions can be made like what we are doing but without having any error message appearing.

It is very helpful that Microsoft makes a 'Canary Tenant' available to test existing solutions with upcoming changes to the platform. This helps us to catch potential breaking changes early.

However, it turns out that only new functionality is rolled out to the Canary Tenant, not other changes. For example this caused major problems with our customers when Code Based sand-boxed solutions were discontinued without adequate warning (other than a general announcement a couple of years earlier without a specific date).

Please roll out ALL non-emergency changes to the Canary Tenant before rolling them out globally.
