Installation
You find and install these apps right from your device's store (e.g., Apple Store, Google Store, Microsoft Store). For specific instructions, look at the Office 365 plan, here.
Activation or "Unlocking"
When you launch and work with these apps, you will quickly find limitations, that certain editing features are "locked". Since Office 365 Education is a qualifying subscription, you can unlock the extra features by logging in with your Carleton-Microsoft account, as described by Microsoft for Apple iOS or Android devices. Those Microsoft tech notes also list the locked extra features, and explain how to open documents and find help in each app.
Once activated, this device will be listed on the "My installs" page in Office 365 Admin in Office Online. Since your mobile activations are limited to 5 devices, from there you can deactivate an old mobile installation to allow for a new mobile installation. On these mobile platforms, Outlook can be configured for use with Carleton's Gmail and Google Calendar, though this is not recommended or supported by ITS on personal devices.
