Hello,
Across our company, people using the New Outlook for Windows are suffering the same issue with attachments not opening, previewing or allowing us to save, specifically .pdf file formats.
I've tried running an online Office 365 repair tool, I've also changed the default program for .pdfs from Adobe Reader to Edge on a hunch it was an issue with that. We're up to date on all Windows updates, and switching back to the Old Outlook works as normal.
The same issue occurs when trying to view the file with Outlook Online too.
Is there reported problems with this or a fix I can test/apply to a group please?

2025-02-26T14:18:13+00:00 I have had the same issues. Not just PDF, but even JPG files.
For me it seems to be on shared inboxes, my own inbox is fine.
Again for me the workroun is to forward the message. although you dont need to actually forward it, it iwll open in the forwarded message before you pres send.

2025-02-26T14:51:34+00:00 It seems the regular mailbox works, so as a work around i have the client forward the email to their inbox and the pdf will open. Thats if you dont want to migrate to the classic outlook.
