Office 365 / SharePoint online needs to support opening PDF documents in SharePoint directly to client application (Adobe Acrobat Pro/DC).

As of this request, technical support has stated the only way to open PDF files in Acrobat is to download/save them.

SharePoint On Premise has supported this feature for some time.

Adobe PDF files are as common and Microsoft Office Suite documents and must be editable directly to/from SharePoint Online without the need to down/save edit, and upload which adds user overhead and lowers productivity.

This limit has always been a bit laughable, and is even more so as we develop more client side applications. In SharePoint 2007 we didn't have this limit and were allowed to make our own mistakes. Now that hardware is so much more powerful, we need this limit removed so that we can build enterprise-class applications.

When I rename a folder in the Teams app, the underlying folder is not renamed in sharepoint. This is most confusing.

Something I find myself wanting to do pretty frequently is storing an email attachment somewhere into SharePoint or OneDrive for Business. I want to simply drag the attachment from Outlook directly into SharePoint or OneDrive in the browser. Alas, I cannot. I am forced to save the attachment somewhere (my Desktop, most likely) then either drag+dropping it into SharePoint/OneDrive or using the upload function in SharePoint/OneDrive to get it uploaded.

It should be easier than that. Microsoft, please consider adding this functionality to get even more user-friendly integration between your suite of products.

Document Sets in modern document libraries

The Share button breaks inheritance on an item, and without warning to the user. With the default Permission Level of "Edit" in Team Sites, you can quickly have 100's or 1000's of items with unique permissions. Going forward, any permissions granted at the library or site level can create a situation where new users will see all of the content in a library, except for those with unique permissions.

I would like to be able to disable (hide) the Share buttons at various tiers such as library, site, site collection or web application/tenant.

Allow the site collection admins to customize the template for the standard SharePoint alerts. The current email alerts are confusing, provide too much information to the user and are out-of-date style-wise.

Allow the admins to add common fields, i.e. "Title", "Created By", and include an image and hyperlinks. Also allow adding a CSS style sheet.

I need to be able to check-in or check-out multiple files. I'm not able to do this currently, when selecting multiple documents.

There is a strong need to Group By more than two levels of column data. Example, we use SP to track mosquitos for vector control. I want to Group by Week, Trap Site, Trap Type, Species, Condition, etc... The ability to drill down and see totals for each condition or "Group By" would be fantastic. This leads to the next suggestion, Add Calculated columns to Group By Totals.

Would love to be able to drag & drop email attachments directly from Outlook into a document library. Currently I have to drag them to my desktop and then drag from my desktop into the doc library.

If you have multiple people co-authoring in Excel Online, there are times when you need to open the file in Excel - typically for advanced formatting, etc. If someone has accidentally left the file open in their browser, there is no way to force them out and keeps the file locked. Although not always intentional, it can create a major headache by not being able to simply kick/close out that particular user from editing.

Bring back 'export to excel' to the new document library experience

CMIS is currently not available for:
- SharePoint Foundation
- Office365

CMIS is the standard for interoperability... Not implementing it in all SharePoint products demonstrates lack of openness.
Please let all SharePoint users enjoy interoperability, not just a fraction of them.

SharePoint Online. We really need to set some restrictions of file types that user can upload to a document library.
For example, to deny upload file with extension .bmp and .tiff.

Some features do not work in Internet Explorer but do work in Chrome or Edge but the "Open in explorer" only work in IE.

Please fully support IE11 or enable "Open in explorer" in Edge or Chrome. We need this feature for adoption.

Fully support at least on browser.

where you can select individual folders / files

Add the ability to mass update Content Type using Datasheet view and NOT change the modified date.
