Outlook for Mac not opening or downloading attachments

Hi there,

my Outlook for Mac does not download or open any attachments.

The issue persists with various file types such as jpeg, xls, pdf.

The workaround with downloading the files and opening them from the finder does not work, as I am unable to save the attachments. I do see the attachments by name and icon (e.g. Apple Preview PDF icon)

macOS and Outlook are up-to-date:

macOS Version: 12.5

Outlook Version:16.64

The issue appeared on my newly installed Macbook Air M2 with macOS Monterey. On the old Macbook Pro before I did not encounter this issue.

As is, I just cannot work with an Email client not opening attachments. Thanks in advance for any solution.

Best regards,

ste_si

*** Update: Seems to be caused by the "new Outlook". Going back to the legacy Version solves the issue, everything works fine. Anyone else experiencing this issue? ***

    Yes. I use the music processor program Sibelius which produces files with .sib extension. For years, attachments received with .sib extension would always open the score directly in the Sibelius program. But now the only option for .sib attachments is to save the file first to computer, and open it from there. Although it's only a small change, I'm still finding it really quite annoying! I use Windows 7.

    Had the same problem with one of my customers with a MacBook Pro running MacOS Monterrey. I uninstalled (moved to the trash) just the Outlook app then downloaded a fresh copy of the Office 365 installer and reinstalled the Microsoft apps. That did not fix the problem until I also installed the newest MacOS, Ventura, and the Outlook attachments started to appear again. You could try upgrading your Mac's OS to Ventura to see if that fixes it. That may be all that is needed. I also tested Outlook for Mac (newest build) on a mac running MacOS Big Sur and it did not have this problem, so it looks like it may be limited to Macs running Monterrey.

    In the update to my answer, I wrote that I was able to fix it with an update to the latest Big Sur update. Thankfully I am not having the same issue on other systems running various OS. From following this thread it does seem random.

    Seems that ‘New’ Outlook on Mac does not allow you to open (for whatever reason) or save (for whatever reason) a pdf attachment.

    Don’t MSFT have software QA/test?
