Preview not opening mail attachments

Hi. I had the same issue and was able to fix it by giving Preview full disk access in Apple Menu -> System Preferences -> Security and Privacy -> Privacy tab -> Full Disk Access then add Preview with the plus button after unlocking the padlock.

Hope this helps you,

Hi. I had the same issue and was able to fix it by giving Preview full disk access in Apple Menu -> System Preferences -> Security and Privacy -> Privacy tab -> Full Disk Access then add Preview with the plus button after unlocking the padlock.

SO! After reading this thread I gave BOTH Preview AND Mail full disk permissions and it seems to have worked.... for now.

Apple Menu -> System Preferences -> Security and Privacy -> Privacy tab -> Full Disk Access then add Preview AND Mail with the plus button after unlocking the padlock.

Ok, a combination of dnasralla's and Warty1's bypasses work:

1. Give Preview full disk access in Apple Menu -> System Preferences -> Security and Privacy -> Privacy tab -> Full Disk Access then add Preview with the plus button after unlocking the padlock.
2. After viewing each attached pdf (or having got the error message) Quit Preview in any of the normal ways. (If you right click on the Preview icon, you will see it keeps a copy open of all viewed files, until you quit the app.)

So they are finally posting a fix in the next update:

"macOS Big Sur 11.6.7 fixes an issue where Mail and apps, such as Microsoft Outlook, cannot open attachments if the app required to open the file is already running."

Hopefully this fixes it. I would work for me the first time and then fail. The update says it's because the program was already open. That's why it would work only the first time. Installing now.

Try holding down Control while you click on the attachment in Mail and choose Quick Look Attachment. It's working for me. I can now open multiple pdfs, some of multiple pages, without quiting Preview in-between or dragging the attachments to the desktop..

I resolved this by making giving the mail.app and preview.app Full Disk Access. You need to add them with the '+' sign.

Looks like this issue is addressed with the 11.6.7 update to Big Sur.

Oops, someone already posted this, sorry for duplication, doesn't appear I can delete my post.

I think I've found a way to open attachments within Mail. Control click on it, and then choose Quick Look Attachment. Opens multiple page .pdf s. and also works for multiple attachments.

Issue resolved. Apple just release 11.6.7

Have just installed 11.6.7 and looks like it has been fixed. Was able to open 3-4 PDF files without having to close Preview.

See my comment on 10 June. OS 11.6.7 appears to have fixed the problem. So I recommend that you install the ltest OS.

Do the upgrade to 11.6.7

That should fix it

Many Thanks Warty1, it was as you said moving to OS 11.6.7 did the trick.
