Can not click to open an uploaded files on sharepoint page

Hi @Nghiem Huy Hoang (DPS.MS3),

1.You could check if the PDF is added to the web application’s trusted MIME Type List by running following command as an admin:

Add-PSSnapin Microsoft.Sharepoint.Powershell 
$webApplication = Get-SPWebApplication("web_application_url") $webApplication.AllowedInlineDownloadedMimeTypes

If application/pdf is not present in the list, it means that PDF is not added to trusted MIME types of the web application. Let’s add application/pdf to the trusted MIME Types List by running the below command.

$webApplication = Get-SPWebApplication("web_application_url") $webApplication.AllowedInlineDownloadedMimeTypes.Add("application/pdf") $webApplication.Update()

2. Open SharePoint Central Administration >> Manage web applications >> select the web application url and click on General Settings Drop-down menu, select General Settings >>
   from General Settings page, change the browser handling option from ‘Strict’ to ‘Permissive’.
3. Open Document Library >> Library Settings >> Advanced settings >> select the radio button "Open in the browser".

4. Check all application pools are started

Hi @RaytheonXie_MSFT

Sorry for reply late,

I appreciate your help and your information you provide to me

The PDF has been added to the web application’s trusted MIME Type because my user has uploaded another before. Do you need any details concern? Please let me know
