How can I set Edge-browser as PDF-file previewer in Outlook Desktop?
I wanted the same thing, not needing additional software for the pdf preview in outlook.
Wanting to use edge. However this seems not possible.
I've now found out that when you install Microsoft Power Toys you get a number of cool tools, including a pdf previewer that works in outlook. It is additional software, but at least you don't have to install a separate pdf viewer.
Recently had the same problem
Open regedit
Computer\HKEY_CLASSES_ROOT\.pdf\shellex
Computer\HKEY_CLASSES_ROOT\.pdf\shellex\{8895b1c6-b41f-4c1c-a562-0d564250836f}
For me this one contained {DC6EFB56-9CFA-464D-8880-44885D7DC193}=> this is adobe PDF preview
Change the value to {3A84F9C2-6164-485C-A7D9-4B27F8AC009E} => this is MS Edge PDF preview
You can check both keys under
- Computer\HKEY_CLASSES_ROOT\CLSID\{DC6EFB56-9CFA-464D-8880-44885D7DC193} - Adobe
- Computer\HKEY_CLASSES_ROOT\CLSID\{3A84F9C2-6164-485C-A7D9-4B27F8AC009E} - Edge
this was what I needed to fix it
For me Computer\HKEY_CLASSES_ROOT\.pdf\shellex\{8895b1c6-b41f-4c1c-a562-0d564250836f}
contained {A5A41CC7-02CB-41D4-8C9B-9087040D6098} as the default => which is PowerToys PDF preview.
I replaced with {3A84F9C2-6164-485C-A7D9-4B27F8AC009E} which is Edge's previewer. I was trying to fix outlook but it also fixed explorer preview but I don't use it as much.
I have pdfgear installed. I think somehow that breaks things. Maybe PowerToys tries to use the default PDF program but in this case PDFgear doesn't do previews. I don't know for sure.
it works for me thanks👍
