Hi,
Thank you for posting in Microsoft Q&A forum.
1,Please make sure the Office apps are closed during the installation. If any Office apps are open when Intune installs the app suite, the installation might fail, and users might lose data from unsaved files.
2,You can refer to below articles to deploy Visio/Project individually in Intune.
Deploy Visio and project separately in Intune.
Deploy Visio or Project with Intune to users with Microsoft 365 apps already installed.
Separate M365 apps for Enterprise from Visio and Project standalone
3,==>Additionally, can you tell me if Office 365 apps can be deployed only to device groups or to both users and device groups in Intune?
We can deploy Office 365 apps to both device group and user group. We can also deploy them to a group with both device and user members.
Thanks for your time. Have a nice day!
Best regards,
Simon
