Mandatory Microsoft 365 Apps Suite Update

Canadian Cadet Organizations (CCO) M365 Apps Suite Update

As the Microsoft Office 2013 suite of programs has reached its end of life, the CCO network must upgrade all existing installations across our network to the new M365 Office suite of applications. In order to maintain effective, secure and updated word processing, content creation and communications tools, this new suite of programs will replace all existing 2013 installations. The programs affected by this upgrade will include Word, Outlook, Access, PowerPoint, Excel, Publisher, OneNote, Teams and OneDrive.

As of November 15th 2021, this new suite will be available to install on all CCO assets at the users convenience through the Software Center. The application is a larger package which will take time to download over VPN and even some hard-wired connections. As part of the installation, all 2013 programs will be removed from a user’s computer, so it is important that once the process begins, you allow it to finish.

  1. Ensure you have at least 4GB remaining on your hard drive.
  2. Plug your asset in. Do not perform this update on battery power.
How to check hard drive space
Update Windows 10

1. Click the Windows Explorer icon in the Task Bar.

How to install the new M365 Apps Suite

Shared assets

Users that share assets will not have to run the installation multiple times. The first user to run the M365 suite install will install the suite for all users on that machine. The only exception being MS Teams, which will need a logout/login or possible reboot for the first user to upgrade. Afterwards, Teams will install individually for each user, the first time they login on that asset after the new M365 suite has been installed.

M365 Beta Testers

If you have participated in any of the previous or current beta tests of the M365 Suite, you are recommended to uninstall your current version and install the latest advertisement in Software Center.

While the newest deployment will be the same version as the current beta (16.13801.20960 32bit semi-annual), it will include previously unleased software (Microsoft Publisher) as well as some changes to the language profiles installed.
