Now it has also arrived at the Microsoft 365 Admin Center.  Allocating storage in OneDrive for Business for a selected user. I described the basics in a separate blogpost in January 2020. Here is the original Microsoft Roadmap link with the ID 65148

In the OneDrive tab of an active user, you can now see the default storage for all users (here 2 TB) and the allocated storage space (here 512 GB)

In the past, you could only change the memory of a single user with PowerShell. Now you can do this directly in the Admin Center. Changing the OneDrive storage of a specific user Behind this link you will find a description of how to proceed.

Summary:

Not everyone needs all the storage space the company allocates in OneDrive. And now, no PowerShell knowledge is required to change the storage space of specific people.
