Multiple Personal OneDrive Instances on the same PC
The ability to have multiple instance of different personal OneDrive accounts on a single PC in the same Windows Account.
In OneDrive for Business, you have the ability to sync with multiple organisations at a time. But in OneDrive Personal, only one personal account can be connected to at a time. The ability to connect to multiple personal accounts from the same Windows account would be of great use, especially where a user is part of a family subscription to Microsoft 365 where potentially, there could be 6 people in the subscription.
