Microsoft AuUpdate update packages could not be downloaded

+1 we are seeing this too

@ccsben

I been using the following script for some time now and it was working very well, until I relived it following your post. Apart from getting 0 exit on the script no errors are thrown but it has no longer updated the MSO suite. It looks like it stopped working right around version 16.27.19071500 which is a real disappointment because now I have to figure out another way of getting this suite updated.

I had exactly the same problem today when trying to update, never had a problem before.

Yes, me too. Just got a notification that there were updates available but I am getting the same error message. My system is the same as yours: macOS Mojave 10.14.6

Having the same issue downloading / installing Word, Excel, and Powerpoint releases from 8/12. Outlook release worked fine.

+1 here (The Netherlands, macOS 10.14.6, Microsoft AutoUpdate 4.14 (19081202).
I first updated Microsoft AutoUpdate. Maybe that's the reason.
