Cannot open attachments in Outlook after update to 11.6.6.

What's the link to file a bug report with Apple, and also with Microsoft (though the latter will say it is Apple since it was all fine until the new update)

They can say that all they like, but if it's only affecting Microsoft's products, then it's quite possible they've just never been using Apple's APIs correctly, and some bugfix in the OS is now making that a problem.

I have the same. macOS Big Sure 11.6.6

and in the last few days, I cannot click on attachments in e mails of MacMail without it telling me I do not have permission to view the attachment

if I save the attachment, then I can open it - but I used to be able to open them without saving them

is this an "improvement"??

I have exactly the same issue and have spent about 2 hours on the phone to Microsoft support level 2 and their answer was to download the attachments before opening them which is doable but highly impractical. My iMac won't let me upgrade to Monterey. I have a MacBook Pro running Monterey and it doesn't have the problem at all and neither does my crappy old Windows PC that's about a hundred years old. I'm guessing it's also a one way street and there's no going back to 11.6.5.

I had the same question. The answer seems to be "only with a clean installation," which sounds simple enough. Heck, I clean-installed 11.6.6 hoping it would help.

Now, you may ask, how exactly does one acquire a 11.6.5 Installer.app? That's a lot trickier. I never found an official download source, but I did find an Apple CDN link to what purports to be the 11.6.5 installer on a random website.

So finally, I upgraded to Monterey and all problems gone. I think mac user who are able to do this upgrade this is the only and (swift) fix than waiting Apple and Microsoft’s solutions. I have Early 2015 MacBook Air. So far I don’t see any performance related problems. So may be this can be encouraging for whom are hesitating older Macs may have suffer due to latest MacOs. Good luck to all !

I am also facing the same issue when opening attachment of emails when using MAIL, i also use Thunderbird on my same MacBook but on Thunderbird i am not facing this issue. Hope apple would soon release a patch to get this sorted.

I posted earlier about having the same problem so I rolled up my sleeves and fixed it. I had to download an installer file for Big Sur 11.6.5 and then make a bootable USB stick from it. Then I had to delete my Mac's HD drive using 'disk utility' and use the USB stick to do a fresh install of 11.6.5. There are plenty of YouTube clips of how to do it and this is what I followed.

I am pleased to say that after installing 11.6.5 and the Office 365 suite, everything is back to normal so it definitely IS the Big Sur 11.6.6 update that was causing the issue.

It's taken all morning to sort this and luckily I have nothing stored on my local drive (otherwise I would have needed to back this up first) but the end result is what I wanted.

Thank you Apple for causing a big pain in the arse to a lot of people!

Sorry, almost forget to say that I have also unchecked the 'keep my Mac updated' box which I never normally do and also I have stopped Microsoft updates too. I know this isn't the done thing but I am sure once Microsoft and Apple have sorted themselves out, it will okay to keep everything updated automatically again.

I have this problem too. I tried giving Outlook, Word, Excel, PowerPoint full disk access from Privacy Settings. It no longer ask permissions.

As for PDF, when I switch the default app to Adobe Acrobat, no issue. Only with Preview as the default. But today I revert to Preview as default app to open PDF, it didn't ask for permission, strange.

apple shame! It's a sneaky way to force you to change your computer even if it's still fully functional! I went back to Catalina and everything works perfectly! Apple You must publish that MacBook Pro (Retina, 15-inch, Mid 2014) is not upgradeable to Big Sur! Now I have the serious problem that my Photo library that was opened with Big Sur no longer opens with the version of Photos that runs on Catalina. I lost several days of work trying to fix this mess not caused by me! Apple have been a customer for over thirty years but I am very disappointed by this unfair behavior!

Apple shame!

I have updated to the Big sur v. 11.6.6. and suddenly everything was no more working:

Mail, preview, Outlook, Airdrop... a terrible mess!

I have made all the efforts to fix it, spending our with support and re installing Os from scratch! Nothing to do!

I contacted Apple about AirDrop’s asking for permissions to transfer from my iPhone to late 2014 intel iMac. The phone rep solved the problem by instructing me to go to internet settings on each device, delete my network Not just change it or turn it off- delete it. Restart the devices. Chose my network, It worked. Airdrop is working. Just be sure that you know your network password before you delete your network.

I am having the exact same issue but with Mac Mail. So it's likely not an Outlook issue. The issue appeared after updating to Big Sur 11.6.6. Someone else in the thread said that it only did this when Preview is already open, and I've confirmed the same. If I double click an attachment with Preview closed, it will launch preview and open the attachment. But if Preview is already open, I will get the permissions error. I will file my own report with Apple.

Big Sur 11.6.7 has just appeared in software update. It claims to fix these attachment issues. I will start installing in a moment. Fingers crossed!
