Office in the Mac App Store
Page Last Updated: July 17, 2019 @ 2:35pm Pacific Time

Welcome
Word, Excel, PowerPoint and Outlook were first released to the Mac App Store (aka MAS) on January 24, 2019 - joining the existing OneNote and OneDrive applications that were previously available. The purpose of this page is to discuss best practices and known issues for organizations that are considering the deployment of Office from MAS. There is an official high-level FAQ on docs.microsoft.com that covers the basic questions and you should read this first if you haven't already done so.

Release History and Download Links
Only the latest released build is available for download from MAS.

Common Issues

• Problem: The 'Get Started with Office 365' dialog is not suppressed when the 'OfficeAutoSignIn' preference is set to {true}.
  Fix: This is fixed in the 16.22 MAS build which released on February 12. If you've already set 'OfficeAutoSign' to {true} then this dialog will no longer appear and users will be taken directly to the Office 365 sign-in page.

• Problem: After installing MAS apps, the user sees many keychain prompts when launching apps.
  More Info: This error occurs when the user previously had a CDN-based Office install present on the machine. The previous install created keychain entries that were only accessible to Office apps that were signed with a Microsoft certificate. Office apps downloaded from the Mac App Store are signed by Apple and therefore cannot access the existing Office keychain entries. The result is that the user will be prompted to change the keychain access.
  Fix #1: For each dialog box, enter the local user password and click 'Always Allow'
  Fix #2: Run the NukeOffKeychain tool with the --MAS switch before launching upgraded apps
  Extended Info: Keychain entries created (but not upgraded) with the 16.22 build of Office (February 12 release) will not encounter this issue as access is granted to the Microsoft team ID rather than individual app paths.



• Problem: User sees 'Allow app to access Contacts privacy prompt' when launching MAS apps
  Fix #1: The user clicks Allow or Deny as appropriate
  Fix #2: IT admins can suppress this prompt by importing these Configuration Profiles
  More Info: All Word, Excel, PowerPoint and OneNote users with an Office 365 subscription will see this prompting starting with builds 16.21. If you are upgrading from CDN to MAS builds, users may see this prompt again due to differences in codesigning.
  The Configuration Profiles (updated on 2/12/19) will suppress the dialog for both CDN-based and MAS installs.
  
• Problem: When forcing updates through Jamf Pro, updates get stuck during installation if the app is currently open, and the user receives no notifications that updates are pending
  Workaround: Close apps before pushing the update from the Jamf Server
  Status: Jamf support is investigating as case JAMF-0635688 and with Apple as RADAR 48120258, but at the moment, this appears to be a known limitation of the MDM/VPP architecture. This issue is not limited to just Office apps, but also affects Xcode, Slack, Keynote, Numbers, Pages, etc
  
• Problem: Apps fail to install from MAS and leave behind an unusable .appdownload stubs
  Workaround: Attempt to download the apps again. If installing from Jamf Pro, run 'jamf recon' again. This is fixed in macOS 10.14.4 and later
  More Info: This issue can occur if the connection to the Apple asset server is reset, or if the storedownload daemon crashes. If you see this problem on Mojave, open the Console app, an look at System Reports to see if 'storedownloadd' is crashing with exception 'EXC_BAD_INSTRUCTION (SIGILL)' at the time of Office install. This is being tracked with Apple as RADAR 47685116, and is fixed in 10.14.4 Beta 4 (18E205e)
  
• Problem: The built-in 'softwareupdate' command does not list Office updates
  More Info: This is a known limitation of the command - it only shows first-party updates, and not general MAS app updates
  
            
  
  
• Problem: If Office apps are installed through Jamf Self Service, users cannot obtain app updates either through Self Service or the Mac App Store app
  Workaround: None
  Status: Jamf support is investigating as case JAMF-0635688, but appears to be a known limitation.
  
  
• Problem: The MAS version of OneDrive does not show file sync status in Finder
  More Info: The absence of overlays is a known limitation of OneDrive when acquired from MAS
  Workaround: Deploy the standalone CDN version of OneDrive
  
• Problem: Clicking the 'Get Add-ins' button in Word, Excel, PowerPoint and Outlook launches the browser window
  More Info: This is an intentional difference between the MAS and CDN versions of Office app (to comply with App Store policy). The CDN version will launch an in-app dialog, the MAS version will launch the browser.
