Fix Microsoft Teams Opening OneDrive Instead of Adobe Acrobat for PDFs
Question details
Users are unable to open PDF files in the Adobe Acrobat desktop app directly from Microsoft Teams, encountering an endless OneDrive sign-in prompt instead.
- Product
- Microsoft Teams
- Device & OS
- not provided
- Scenario
- Attempting to open a PDF file from the Microsoft Teams Files tab using the 'Open in app' option.
- Observed behavior
- Instead of launching Adobe Acrobat, Microsoft Teams triggers a OneDrive sign-in prompt. Opening the PDF in a web browser continues to work correctly.
Ensure that Adobe Acrobat is set as the default PDF viewer in your system settings and verify that your Microsoft Teams application is updated to the latest version.
Deploy the Adobe Acrobat App within Microsoft Teams
Since the desktop app routing may be bugged in the new Teams client, using the native Adobe Acrobat app integration inside Teams serves as a reliable workaround.
By integrating the Adobe Acrobat application directly into your Microsoft Teams workspace, you can view and interact with PDFs without relying on the operating system's desktop app handler.
Click on the 'Apps' icon located on the left sidebar of the Microsoft Teams interface.
Type 'Adobe Acrobat' into the search bar and select the official application from the results.
Click the 'Add' button to install the app for your personal view or within a specific team workspace.
Follow the on-screen prompts to set Adobe Acrobat as your default PDF handler inside Microsoft Teams.
Open PDFs in the Web Browser
Bypass the desktop application routing error entirely by opening the PDF directly in your default web browser.
Report the Issue and Open a Support Ticket
This is a recognized integration bug with the new Microsoft Teams app. Reporting it helps Microsoft investigate and expedite a fix.
Use WPS Office for Seamless PDF Management
If you are experiencing integration issues between Microsoft Teams, OneDrive, and Adobe Acrobat, WPS Office provides a robust, lightweight, and free alternative. It includes a powerful built-in PDF editor that works seamlessly with your local and cloud files without unexpected authentication loops.
- 1. Download the Installer: Visit the official WPS Office website and click on 'Download WPS Office Free'.
- 2. Install the Software: Run the downloaded setup file and follow the on-screen instructions to complete the installation.
- 3. Set as Default PDF Viewer: Open your system settings and set WPS Office as your default application for opening PDF files.
Frequently Asked Questions
Why does Microsoft Teams prompt a OneDrive sign-in when opening a PDF?
In the new Microsoft Teams app, the 'Open in app' routing for PDF files may incorrectly trigger a OneDrive authentication prompt instead of passing the file to your default local PDF viewer, such as Adobe Acrobat. This is currently recognized as an integration bug in the new Teams client.
Can I change the default PDF viewer natively in Microsoft Teams?
Microsoft Teams generally opens PDFs in its built-in viewer by default. To use external applications, you must either select 'Open in app' for desktop viewers or install a specific app integration, like Adobe Acrobat, directly into your Teams workspace.
Does opening the PDF in a web browser still work if 'Open in app' fails?
Yes. If the desktop 'Open in app' option fails and results in a sign-in loop, you can click the three dots next to the file, select 'Open', and choose 'Open in browser' to successfully view the PDF.
