Office Online Server integration with SharePoint server 2019. Issue with viewing documents in browser from SharePoint site..

Shuvajit Roy 146 Reputation points

I deployed Office Online Server and found the server working properly. I performed "Get-OfficeWebAppsFarm" and found the elements in place. I integrated OOS with SharePoint server 2019. I observed that through "Get-SPWOPIBinding" I get the response from the system as desired.

However, I cannot open documents in browser. Word, PowerPoint, excel and pdf file directly download without opening in browser.

SharePoint and OOS are in Windows server 2019 Standard. I also performed "ooshostname/hosting/discovery" and found the XML in browser. 2023-08-29_12-55-27.png

    Which browser you are using?

    If you are using Chrome, it is how the Chrome browser works.

    To resolve this issue, add "?web=1" to the end of the URL. Then the document will be opened in the Chrome browser. For example, http://sharepointserver/Shared%20Documents/DateTest.docx?web=1.

    For IE and Edge, please follow below tips to troubleshoot.

    1.Run this command: Get-SPWOPIBinding | Set-SPWOPIBinding -Defaultaction:$true

    2.Go to Site Settings -> Site Collection Features -> Deactivate the feature Open Documents in Client Applications by Default.

    3.Go to Document library settings -> Advanced settings -> In the Opening Document in the Browser section, choose Open in the browser.

    4.Clear browser cache, then try to open files in the browser.
