On-premise Office Online Server is not working with the web client

I assume you followed both Enabling Microsoft Office for the Web Services for M-Files and Setting Up the Office for the Web Backend Service for the New M-Files Web to set up the necessary services.

After everything has been set up properly, you should be able to launch Office for the web by double-clicking the document in the listing and checking it out to editing. This would open Office for the web in a separate tab. There won't be any new option in the context menu as far as I tell.

Unfortunately, when I double-click a document it only downloads the file.

I followed the necessary documents where “Setting Up the Office for the Web Backend Service for the New M-Files Web” redirects me to M-Files online User guide

"This document is for M-Files September '22 Update and earlier. If you use M-Files October '22 update or later, instead refer to Setting Up Web and Mobile Access to M-Files."

I believe the point of that note is that if you use the new wizard-style option to enable M-Files Web via M-Files Admin, then it will also automatically configure the backend for Office for the web at the same time.

However, if you have enabled M-Files Web manually earlier (following the instructions in Setting Up the Backend for the New M-Files Web and Web-Based Add-Ins) then you'll need to also enable the Office for the web backend manually following that guide.

Hi Joonas,

Thanks for your help so far, I did use the wizard-style to enable M-Files Web, it's a brand new install.

I tried enabling Office for the web manually but that results in an error when clicking “View Rewrite Maps”

Perhaps a conflict with the settings configured by the wizard

If you enabled M-Files Web via the wizard then the Office for the web backend should be in place. You could raise this with support as it doesn't seem to be working as documented.
