Since upgrading to Big Sur 11.6.6 any email attachments in Mac Mail (ppt, pdf, word) require permission to open. Attached an example when opening a pdf.
I checked and I have read & write permission on all the relevant folder, containers and files.....
Advice from help desk was to simply update to Monterey - which doesn't really fix the problem.

There are numerous threads on this and it is a bug. Please file a bug report with Apple. They will not take it seriously until enough folks make sufficient noise.
You can do that here:
There is a way to open those attachments but it is a PITA -- essentially quit the necessary app. click the attachment and it will open, but to open the next one that requires that app, you have to quit the app first.
In a post below someone mentioned that the solution is to upgrade to Monterey. For some fo;ls (like me) that gets done on the last update of every OS before the next OS is introduced - I can't afford downtime dealing with bugs mid-stream; for others, it is a matter of "this is as far as I can take this machine", or the need to use a certain app or a particular printer that is not compatible with Monterey.
Apple does not read these discussions, so you might want to tell them in your bug report why this is negatively impacting you in a counterproductive way.

Well I ended up upgrading to Monterey and the problem did go away!
Exactly the same problem on the same OSX.
Happened just after I had to restore my whole system from Time Machine so thought it was related to that.
I can download the attachments and open them but not open them in the mail app.
Any advice would be much appreciated.
Thanks for the information. My iMac is on it's last legs and I had to wipe the disk, reinstall Big Sur and restore from Time Machine.
I've have a replacement on order but not being delivered until July.
Can't risk a shutdown, never mind an upgrade.
I need to limp on with this for my work as long as possible!
I spoke to telephone support and after trying to update my permissions also suggested an upgrade to Monterey. They did mention other people were facing the same problem.
Thank you. I can open attachments after I've downloaded them but it's hardly ideal.
I've given feedback as you suggest.
I, like you, install the latest OS very late in the game for the same reasons.
I found this, hope it helps https://www.fireebok.com/resource/how-to-fix-when-you-do-not-have-the-necessary-permission-on-mac.html
