      No Comments on Even more changes to Microsoft AutoUpdate preferences

Microsoft AutoUpdate 4MacAdmins have grown accustomed to Microsoft adding new, useful managed preferences to AutoUpdate and Office over the years.

So it comes as a surprise when widely used preferences are removed seemingly on a whim with no warning.

Recently I’ve written about two unexpected changes to Microsoft AutoUpdate (MAU):

Yesterday a member in the MacAdmins Slack spotted a new Microsoft document that contains even more changes to MAU preferences.

Read on for a little commentary plus what I think are the most noteworthy changes…

Changes to Microsoft AutoUpdate deferral options

      1 Comment on Changes to Microsoft AutoUpdate deferral options

Microsoft AutoUpdate 4Microsoft began offering curated deferral channels for AutoUpdate a little over two years ago. These feeds allowed MacAdmins to delay updates to Office apps for a set number of days, without having to run a custom manifest server themselves.

Unfortunately these deferral channels have recently stopped working, leaving many MacAdmins scrambling to adjust.

Thankfully the community has engaged Microsoft and have pushed for a solution.

Read on for the details on why this happened and how to adjust your configuration.

Optimization preference added to Microsoft AutoUpdate

      1 Comment on Optimization preference added to Microsoft AutoUpdate

Paul Bowden shared a new preference for Microsoft AutoUpdate last month that configures the method MAU uses to apply updates. The preference was created to work around security agents that can cause problems when updating Office on macOS.

The option is just now being highlighted despite being added to MAU 4.40 back in October 2021. Read on for the details.

Microsoft’s Paul Bowden announced on Tuesday at Virtual JNUC 2021 that the company is now providing additional update channels that support deferring updates for periods of time and even pausing updates on specific versions of Microsoft Office for Mac.

While these new options were announced at JNUC and Jamf Pro has native support for configuring them, MacAdmins who use a different MDM can also utilize them with custom configuration profiles right away.

I reached out to Paul for more details and clarification on these exciting new options. Read on for the details.

MAUCacheAdmin has been updated to version 3.0

      No Comments on MAUCacheAdmin has been updated to version 3.0

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.com

Also 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.

If your company has Office 365 subscription licenses you can stop reading here. Nothing changes for you and your users will always have the latest features as soon as they are released. However if you deploy the Volume Serializer keep reading for what’s new.

Suppressing Microsoft AutoUpdate’s new macOS Upgrade alert

      No Comments on Suppressing Microsoft AutoUpdate’s new macOS Upgrade alert

Microsoft Office officially dropped support for macOS 10.12 Sierra last week with the release of the 16.31 updates. This came as no surprise to MacAdmins as the Office for Mac team announced the N-2 macOS support plan back on Sept. 4, 2018. What did come as a surprise was a new Microsoft AutoUpdate (MAU) alert encouraging users to upgrade to macOS Catalina.

This obviously presents a problem in managed environments where end users are not able to upgrade themselves directly though the App Store. While most admins should focus their efforts on upgrading computers to a newer version of macOS, in environments where computers must remain on Sierra or older, suppressing this dialog is desired.

Thankfully it is possible to do so with a configuration profile, read on for the details.

Microsoft AutoUpdate Daemon renamed

      1 Comment on Microsoft AutoUpdate Daemon renamed

A last minute decision to rename Microsoft AutoUpdate’s daemon from “Microsoft AU Daemon.app” to “Microsoft Update Assistant.app” in version 4.15 caused an unexpected dialog to appear for users last week.

MacAdmins have been suppressing this standard macOS dialog for several years by pre-registering Microsoft AutoUpdate in the Launch Services database. The sudden name change caused the dialog to unexpectedly appear during the monthly update cycle of Microsoft Office in September.

Read on for details of what needs to be updated in your script to suppress this dialog for users going forward.
