Cannot open attachments in Outlook after update to 11.6.6.

Hi Again

Just finished installing 11.6.7. I have tested opening various attachments in both Outlook and Mail and it would seem that the problem has been fixed. This is on my trusty old MacBook Pro (Retina, 15-inch, Mid 2015).

I hope everyone else finds that the update has fixed the problem too.

This made my day. I had been so annoyed by this that I ended up starting a support chat with Apple the other day just to see if they were aware of it. It didn't seem they were and the first response was "upgrade to Monterey" but I have my own reasons for not wanting to upgrade just yet. So I kept at it, and ultimately had a long phone call with a senior support technician who was helpful but didn't think this would be treated with priority.

I won't claim credit but it sounds like collectively we made enough noise for someone to have a look.

I've just applied the update and sure enough, everything is working great. Thanks Apple!

The release of macOS 11.6.7 this week had a line item about opening attachments in Outlook. I would apply this update, ensure that you have the current Outlook installed, and see if the problem has gone away.

not surprisingly, upgrading to 11.6.7 resolved the issue on my mid-2014 MacBook Pro and late-2014 iMac as well - huge relief - curious though, in light of what must be scads of these older, yet still viable, systems in use, that, unless i missed something, none of the Apple Care techs mentioned by this forum's contributors seemed familiar with the issue or its imminent fix, considering Apple's software engineers had to become aware of the issue, then design & test the fix before distributing 11.6.7 - to have heard AC techs report Apple was aware of the issue and working to fix it would have been reassuring, not to mention saved many of us several hours of re-installs and risky workarounds - was it a nefarious equipment upgrade marketing scheme? - did someone working on 11.6.6 make an Apple-embarrassing mistake? - what actually happened may remain forever shrouded behind Apple's cloak of proprietary secrecy - many thanks to all the contributors for making all the noise you did, whether or not Apple already knew what was up - this guy is just very happy to be back in business and thankful for the forum - stay well folks - blessings

I hope that everything will run well. In the meantime I have downgrade to Catalina and here remain. I have lost three full working days to try all the new installations and I have no longer patience to try and may have another problem.

Stay well and thanks

This is Apple's bug alone. I can reproduce this bug on a clean install of 11.6.6 prior to installation of anything third-party.

There is a link a few posts above yours!

Feedback - macOS - Apple

Looks like this issue is addressed with the 11.6.7 update.

Just ran across the problem myself.

Hope this helps.

Booting into Safe Mode did no good. Problem persists. Have used Feedback Assistant to contact Apple; have altered Microsoft as well. Will call Apple Care later when I have time.

@lipo2lipo yes that's correct.

With Preview already open and double clicking the temporary file in finder it also works. So the problems seems only to occur in combination with outlook ...

I have the same issue in Apple mail, the only workaround for this is to change defaults for pdf. and use Acrobat Reader but it is very annoying that this stopped working properly.

Please file a bug report with Apple ... not going to get fixed until they know the issue is prevalent.

Yes, thank you. If you shut down Preview, image attachments certainly seem to work.

Same for me.. I am assuming this will be come a big problem and eventually apple will have to release an update
