Using Windows 11 amnd MS Office 265, Outlook Version 2408, 16 bit, I cannot preview PDF attachments. My Adobe program is Acrobat Pro.
I get the error "This file cannot be previewed because of an error with the PDF Preview Handler" in both Outlook and File Explorer. It started when I had to reset my computer for another problem, and after I reinstalled Adobe Pro. Double-clicking the attachment will open the file within Acrobat Reader DC as expected. Many people have reported the same problem and suggested many solutions which I have tried and delineate below.
- The PDF file icon represents that Adobe is the default.
- Other previewers (Word, Excel and PowerPoint, for example) all show file attachment previews as expected.
System configuration:
- Lenovo evo with >150gb of available disk space
- Windows 11 with all current updates
- Office 365 with all current update
Already tried:
- Verified i am using 16 bit Office and Adobe.
- Verified that Adobe Reader DC has all its defaults set correctly.
- "Repaired" Adobe Reader DC.
- In Outlook, I have gone to “File > Options > Trust Center > Trust Center settings > Attachment Handling” and confirmed the “Turn off Attachment Preview” box is unchecked, and “PDF Preview Handler” is enabled/ticked in the list in the opened window.
- Confirmed I am not using Power Toys.
- Verified the registry entries that were mentioned in other troubleshooting suggestions and verified that one entry was not there per another suggestion.
- I have note uninstalled and reinstalled Office or Windows, except when I reset the computer and the problem arose.
Any other potential options would be appreciated.
Thanks much for any assistance,
Phil
