I want to sync my SharePoint files to my desktop using CmisSync.
To do this, I need to activate the CMIS protocol on SharePoint.

So, how to access documents stored inside SharePoint Server 2013 from outside, via CMIS?

  • thank you for this article. I installed CMIS on my SP server .. and now i'm trying to test it in a winform app. I added a reference to the service, but honestly i can't find a way to use the methods within this service. ( i want to display the data in a list i have in a sharepoint site (for xpl) in a listbox control.)! Thank you Fadwa

  • @user15425 CMIS is not supported for SP List, check the details at Configure CMIS In SharePoint 2016 May 10 '20 at 23:49

Step 1: Make SharePoint accessible from outside (if not already)

On the server, start a powershell window and type the following commands:

Add-PSSnapin Microsoft.Sharepoint.Powershell
Get-SPWebApplication -IncludeCentralAdministration

Take note of the URL at the SharePoint Central Administ... line, then open it in a web browser.

An administration web interface appears. Click on Application Management then Alternate Access Mappings then Edit Public URLs.

In Alternate Access Mapping Collection select the site you want to access, probably something like SharePoint - 80. In Public URLs set Default to the URL you must use to access the server, which is probably http:// or https:// plus the server name you would use to ping the server from a client machine.

Step 2: Enable Basic Authentication (if needed)

(If you want to access via NTLM/SSO, skip this step)

Return to the main page of the SharePoint Central Administration tool. Click on Security, then in the General Security section click on Specify authentication providers, then on Default.

In this page, set Basic Authentication to checked.
Note: To stay secure, make sure you use HTTPS.

Step 3: Activate CMIS for your site

Log into the web interface of your site, click the gear icon in the upper-right, click on Site settings, then in the Site Actions section click on Manage site features. In the list that appears, activate the Content Management Interoperability Services (CMIS) Producer item:

Step 4: Use CMIS

In your CMIS client (for instance CMIS Workbench), use the following URL:


(or http://yourserver/_vti_bin/cmissoapwsdl.aspx if using Web Services)

and your SharePoint username/password.
