Hi @Mtecs-Togawa ,
As tag "office-itpro" focuses more on general issue of Office desktop clients, I do not have the devices with Windows Holographic OS, so I could not do tests for you. Following information is from some Microsoft articles, hope it could be helpful.
According to the article "About HoloLens 2", we know that HoloLens 2 runs on the Windows Holographic OS, and then based on the link "Windows Holographic, version 21H1", we could know that you could install the Microsoft Office web app from https://www.office.com to view and edit files hosted on SharePoint or OneDrive.
For Office desktop clients, so far I do not think they could be installed on this device. As Windows Holographic OS does not meet the Operating System requirement for Office desktop clients.
More information you could checkout "Microsoft 365 and Office Resources".
Besides, to have a confirm, it's recommended to ask the seller, on the webpage ‘https://www.microsoft.com/en-us/d/hololens-2/91pnzzznzwcp?activetab=pivot:overviewtab’, you could talk to an expert.
Thanks for your understanding.
