MAUCacheAdmin was updated to version 3.0 this afternoon to account for a change in the CDN infrastructure that serves Microsoft Office for Mac updates. As was reported in the #microsoft-autoupdate channel of the MacAdmins Slack yesterday, version 2.9 was marking every package as corrupt and re-downloading them all on each run.
From Paul Bowden’s commit notes:
In the October 2021 update, Microsoft moved to a new CDN namespace (officecdnmac.microsoft.com) which supports HTTP/2
However, the previous version of MAUCacheAdmin relied on the HTTP/1.1 ‘Content-Length’ header – which is all lowercase in HTTP/2
So:
1. Changed awk search to grep -i as it’s still possible for the new CDN to emit a HTTP/1.1 response in some cases
2. Changed main URL definitions to new namespace of officecdnmac.microsoft.comAlso fixed up a few other problems:
* Removed MAU 3.x definition
* Added 365/2021 to existing 2019 title (visual change only)
* Updated copyright year
MacAdmins who run a MAU Manifest and/or Caching server should update to the latest version of the code to prevent these looping downloads.
On Sept. 16, Microsoft released Office LTSC for Mac 2021 to commercial customers ahead of the October 5 launch to general consumers. LTSC, or Long Term Servicing Channel, is the new official name of Office for customers with a perpetual Volume License.
