In a surprise – but welcomed – move, Microsoft announced yesterday that the office support lifecycle for Office 365 ProPlus on Windows 8.1 and Windows Server 2016 are extended to January 2023 (EOL of Windows 8.1) and October 2025 respectively. In addition, Office 2016 connectivity support for Office 365 services will be extended to October 2023 (was 2020).

Other announced changes in product support lifecycles were extending Windows 10 Enterprise & Education support from 18 to 30 months. Also, for Windows 7 Professional & Enterprise, paid security updates (Extended Security Updates) will be offered, and those Windows 7 ESU devices will be supported through January 2023 – parallel to Windows 8.1 – with Office 365 ProPlus.

Office 2016 for Mac, like most Microsoft products, has a support lifecycle during which we provide new features, bug fixes, security fixes, and so on. This lifecycle typically lasts for 5 years from the date of. Today we mark the end of support for Office 2010 and Office 2016 for Mac. This means that we’ll no longer provide technical support, bug fixes, or security updates for these products, and organizations that continue to use them may face increased security risks and compliance issues over time.

The intention of these changes is to provide customers more flexibility in adopting modern desktops on the client end (i.e. Windows 10) and upgrade their Office suite, preferably to the susbscription-based ProPlus. The release cadence of the cloud has significant impact on organizations, which were told in February to keep in line with product releases as a lot of product support lifecycles were going to end in 2020.

Extending those dates not only gives them more flexibility to plan and upgrade, but also might prevent organizations to do only to the minimum, which is likely the reason many organizations are still on Windows 7 and why it took many organizations a long time to get rid of Windows XP.

Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Summary

Existing Office 2016 for Mac customers will be seamlessly upgraded to 64-bit versions of Word, Excel, PowerPoint, Outlook, and OneNote as part of the August product release (version 15.25). This affects customers of all license types: Retail, Office 365 Consumer, Office 365 Commercial, and Volume License installations.

Deployment options for the 64-bit update

Office 2016 For Mac Os

AutoUpdate (MAU)

Customers who use Microsoft AutoUpdate (MAU) to keep their Office applications up-to-date will see a 'regular' monthly update notification when their selected channel is upgraded to 64-bit builds. Depending on which version is installed on the local computer, MAU will offer either a delta or full update. The update package size does not change between 32-bit and 64-bit versions. Also, MAU can deliver a delta update when applicable to update a user from 32-bit to 64-bit applications. Therefore, customers won't experience a sharp increase in download activity. For the release to the Production channel, customers will see '(64-bit)' in the update title to make them aware that this is a 64-bit update.

For information about how to use the MAU, see Check for Office for Mac updates automatically.

Manual updates

The August release of Office for Mac is available for manual download. The following file provides a 64-bit package to replace existing 32-bit applications with 64-bit variants during installation:

Virus-scan claim

Microsoft scanned this file for viruses, using the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help prevent any unauthorized changes to it.

Volume License Service Center

Volume License customers typically get their Office 2016 software from the Volume License Service Center (VLSC). These builds are refreshed infrequently and are typically aligned with new language editions. The VLSC will continue to offer 32-bit installers (15.23) until November 2016. However, all updater packages that are released after August will be based on 64-bit builds. Therefore, a VLSC customer who updates either manually or through AutoUpdate will be transitioned to 64-bit builds.

More Information

64-bit only

The Mac operating system has been 64-bit for several years. Unlike for Windows, there's no choice between running a 32-bit or 64-bit version of the Mac operating system. Similarly, we won't offer a choice between 32-bit and 64-bit versions of Office 2016 for Mac. After each 'channel' is transitioned per the rollout schedule, only 64-bit builds will be available.

Effect on third-party applications and add-ins

The transition to 64-bit Office for Mac was announced in April 2016. IT Pros will want to understand which compiled add-ins are deployed to the users whom they manage so that they can assess the effect of the upgrade. The following Microsoft Office website summarizes the issues that affect the more common add-ins that are used together with Office 2016 for Mac:

Tools for inspecting product architecture

To verify the architecture of an Office application (that is, to understand whether you have a 32-bit or 64-bit build), start the application, open the Activity Monitor, and then enable the Kind column.

Cultist simulator: anthology edition for mac. You can also use the file command in a terminal session to inspect the binary. For this use, type file -N <path of binary>.This method can be used with for any binary file, including third-party add-ins.

The file command returns one of three values.

Return value	Meaning
Mach-O 64-bit executable x86_64	64-bit binary
Mach-O executable i386	32-bit binary
Mach-O 64-bit executable x86_64	FAT binary (compatible with both 32-bit and 64-bit processes)
Mach-O executable i386	FAT binary (compatible with both 32-bit and 64-bit processes)

Options for reverting to 32-bit installations

There may be situations in which the customer has to change code that's not 64-bit ready. If customers can't immediately move forward to 64-bit builds, we will make available a one-time 32-bit update for the 15.25 release in addition to the default 64-bit updates. The 32-bit updates will be available only for manual download from the Office CDN.

The latest 32-bit release of Office 2016 for Mac (15.25.160818) can be downloaded from https://go.microsoft.com/fwlink/?LinkId=823192.

Customers who manually install the 32-bit release won't be offered the 64-bit version of 15.25 through MAU. However, MAU will offer the 64-bit version of 15.26 in September 2016. Therefore, customers have a limited time to remain on 32-bit builds.

If a customer has already upgraded to the 64-bit update of Office for Mac 15.25 and wants to revert to the 32-bit version, follow these steps:

Exit all open Office 2016 applications.
Start Safari, and then browse to https://go.microsoft.com/fwlink/?LinkId=823192 to start the download of the 32-bit installer.
Double-click the downloaded package, and then follow the instructions.

The 64-bit installation has a build date of 160817. The 32-bit version has a build date of 160818.
