Creating link to document in Sp2019 On Premise

Question

We are have issues with the link that is created when chosing ... Copy link in document librarys.

The last part of the created URL: xxxx.xlsx?csf=1&e=lZbyNW , in this case when using the link the user gets message if he/she trusts the content etc. before opening the actual document, if we remove everything after xxxx.xlsx.... the link works fine and the document opens directly.

How do we get around the creation of ?csf= when copieing links?

Answer 1

Hi @Jonsson, Lars Konsult ,

This this the behavior by default. Csf=1 means added when sharing with People with existing access.

As mentioned, similar to:

d= xxxx – this will help creating a unique URL to allow opening the file in the browser. If you remove this parameter, you’ll get a download request. This parameter is only added when you share with People with existing access.
Csf=1 – added when sharing with People with existing access
Web=1 – opens the file in the browser
E= xxxx – The purpose of this parameter isn’t really known; if you remove it, the Share will work the same way.

Answer 2

Hi @Jonsson, Lars Konsult ,

Like Elsie said, "csf=1" is added when sharing with people with existing access, this behavior is similar to SharePoint Online.

Did you configure Office Online Server(OOS) for your SharePoint 2019 environment?

In my environment, I just have SharePoint 2019 (16.0.10371.20043) without OOS. I copied the link of an Excel file from a library via "Copy Link", then used the copied link with "?csf=1" directly to access the file again, it downloaded the document, which is a normal result without OOS.

The copied link I used is:
http://v19/Shared%20Documents/New%20Text%20Document.txt?csf=1&e=cSRwr4

Result:

Also, if I remove "?csf=1..." after the coped link, and use the new link to open the file, it also redirects me to download the file.

So, please have a try and let's know your result.

Answer 3

Would the OOS help us in this case.
Right now staff who like to share a link with others with access to a document need to remove the "?csf=1..." for the user so they don't need to go trought the hazard of clicking on "would you like to open the file "xxxx" pop-up?
