How to enable Co authoring for Microsoft 365 (Online)

Please refer to the user guide:

• Enabling Desktop Co-Authoring - The new co-authoring option using Office desktop applications. Read more here: Desktop Co-Authoring in M-Files
• Enabling Web Co-Authoring - The older co-authoring option using Office for the Web (browser-based). 

Joonas Linkola Thank you , I have gone through those, Do we still Need Office Online server for M365 as well ?

If running M-Files on-premises, Office Online Server is a requirement for the web co-authoring.

Desktop co-authoring is only available on M-Files Cloud.

Hi Joonas Linkola ,
Is Co-Authoring with Microsoft SharePoint supported anymore? M-Files user guide: Checking Out a Document for Co-Authoring with Microsoft SharePoint

I cant find referenced document from the kb: Customizing Co-Authoring and Sharing Features.
