Hello.
I just upgraded my client's unsupported macOS Ventura v13.7.8 to Sequoia v15.7.1 because Apple and Microsoft dropped support recently. I'm currently unable to upgrade his installed Mac Office (university's 365 subscription) v16.101 to v16.102. It queues the updates and then "Download error..." ? was useless.
I tried rebooting and trying another macOS account. Nothing helped.
How do I fix this? :( Thank you for reading and hopefully answering soon.

Hi ,
Try updating directly via the PKG if you are going to uninstall Office and install the previous version.

Thanks
Hi ,
I understand some users had to remove and install the package I sent, but you can stay on update 101 until 102 is fixed.
Thanks
Ivan, I am going to wait since other users are having the same issue. I want to be sure AutoUpdate works again when it is finally fixed. Do you know how many users have this problem?
Hi ,
Sorry, I can't say how many users are having the problem based only on this Q&A, if you want, wait for it to be fixed, that's fine, we're here to help.
Thanks
