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.

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.

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 a task list web part for the Modern Page experience.

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

■Title(件名)：アイテム単位での閲覧数の確認について

Implement the feature to check the number of view by item unit.

■Description_JP (内容):アイテム単位での閲覧数を確認したいが、Office 365 監査ログ レポートにて、アイテム単位での閲覧数の出力が出来ません。そのため、Office 365 監査ログ レポートにて、アイテム単位での閲覧数を出力する機能の実装を希望します。

I want to check the number of viewing by item unit, but I am currently unable to output it by using Office 365 audit log report. Therefore, I hope the feature will be implemented to output the number of view per item.

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?

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.

We've just converted the site collections at a client site from path-based site collections to host-named site collection and discovered that calendar with overlays of calendars from other site collections do not work once we've made the switch to HNSC.

Please enable the ability to use calendar overlays using calendars stored in other host-named site collections. This is an issue with host-named site collections that is disappointing considering Microsoft is recommending the use of HNSC.

If it's a valid name in Windows, it should be also in Sharepoint.

■Title(件名)：
Stream の動画にて、視聴途中ではなく視聴が完了したかを確認できるようにしたい
We want to check if Stream videos have been viewed completely instead of being unfinished

■Description(内容):
現行の Stream の挙動では、視聴が途中の動画であったとしても、[*回のビュー]​ として表示され、視聴途中か視聴完了したか区別ができません。
また、監査ログにおいても同様に、視聴途中と視聴完了の区別ができません。
視聴が完了したか確認できる機能の実装を希望します。
Currently Stream behaves in a way that even if a video was viewed incompletely, " * views" will be displayed and it is not possible to distinguish whether the video is unfinished or completely viewed.
The same goes for the audit log, it is not possible to distinguish between an unfinished video and a completely viewed video.
We hope that a feature to check if viewing is complete will be implemented.

In the SharePoint site usage page "_layouts/15/siteanalytics.aspx?view=19" it would be good to have the number of users following the site. This information is not available anywhere but it's very important in a corporate context.
For an Hub site it would be good to have the number of followers of the Hub and the aggregated number of followers of the sites associated to the hub (nice to have)

On the page of Statistics in Office 365 video, the displayed number of “Watched” differs from the actual number of watched.
I really want this will be improved in the nearly future.
