3.5.2 Outlook preview broken
SumatraPDF version 3.5.2
Describe the bug Previewing PDFs in Outlook (Microsoft 365 desktop app) no longer works, gives "This file cannot be previewed because there is no previewer installed for it" error. I've switched back to 3.5.1 and it's working again.
Yes, I selected the option to have Windows use SumatraPDF to preview documents when installing 3.5.2.
if it works for 3.5.2 it should work for 3.0 - 3.6 but the common problem may be which variant 32bit or 64bit since it must be same as outlook variant.

Both were 64-bit.
3.5.1 => 3.5.2 had very conservative changes that didn't touch anything related to previews so it's unlikely that 3.5.1 works but 3.5.2 doesn't.
Recently Microsoft likes to steal .pdf handling for Edge so I would rather blame that.
