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)

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?

■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.

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.

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.

The SharePoint Site usage report under O365 Admin Portal includes only two templates (Group and Team sites)

A tenant may have other types of sites like publishing, document center, etc. As this report has only two templates, the report isn't accurate and isn't helpful.
It will be great if all the SharePoint templates are included in the report.

Currently, they only way to provision a workflow to site collections is to use the exported wsp-files from SharePoint designer. This however requires custom scripting to be enabled.

For on prem you may use a farm solution but this is not applicable to SPO.

If this was handled by the content type hub there would be no dependencies on the old feature framework.
