Outlook Previewer not aligned for PDFs

[kvansplunder]

As of only recently my Outlook previewer is shifting all PDF files to the left so that only 1/2 of the page is shown.  The complete left side of the page is hidden/cut-off.

Same problem here although in our case the alignment cuts off the right side of the PDF and leaves a lot of blank space on the left side. Our version is Outlook 365 (version 2202 build 16.0.14931.20128) 64bits

We tried disable/enable PDF preview handlers (there are 2 of them showing in trustcenter\attachement-handling), disabling/enabling email previewpane. Switching previewpane from right to Bottom makes the PDF preview "unreadable" small. My guess is that this happened after an update. Lets hope someone at MS can confirm this. It's driving me nuts....

I've been having the same issue for what seems like months now with no resolution. I'm glad it's not just me but would really appreciate some help or a resolution here. Thank you!

@kvansplunder I had this issue today.. Bottom left hand corner of display settings -> changed from optimise for performance to compatibility mode and now all is working again.
