Blocking o365/MS-Team accessing from multiple device

[Thoufeeque]

Hi Team,

Please advise on my query,

1.Blocking o365/MS-Team accessing from multiple devices,

2.It should be accessed by one device at a time or it should be accessed only with the device for which it's allowed to access (mobile/tablet/PC/Laptop).

Please do the needful if we have such policy or custom policy to be created.

You could use Azure AD Conditional Access policies to allow only access from for example managed/compliant devices to Microsoft Teams. This would mean that you would need to start managing those devices in eg Endpoint Manager though. I'm not aware of any other possibilities to achieve what you're asking.
