Hi team,
I assigned Microsoft 365 Apps for Business license to a guest user in my tenant. The license assignment is successful but it seems guest can not really use M365 apps (Word, Excel, etc). The guest user gets error message when to access M365 app after successfully sign in to my organization.
Also, the guest user cannot pass the license authentication in a desktop M365 app.
Is this intended behavior?
Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Managing external identities to enable secure access for partners, customers, and other non-employees
This is not a supported scenario, guest users can only use the web apps indirectly, by accessing documents shared with them. Instead, the guest should ask for license in their "home" tenant.
@Vasil Michev thank you for your answer. just wondering then what's the supported scenario where a guest is assigned a M365 license
Some services might require Guests to be licensed, but overall, this is not required. For example, accessing files shared with the user in SPO/ODFB does not require a license. Even if it's technically possible to assign one, doing so will not grant the user access to additional resources. I.e. adding an Exchange license to the user will not result in provisioning a mailbox.
If you do want to assign a license for some reason, best convert the user to "member", so he gets full access to the directory/resources.
