There is not enough space on the MS Exchange server to create a VSS snapshot of the database because the maximum size of the shadow storage area is too small.
To resolve this issue, consider resizing the shadow storage area on the MS Exchange server.
Please refer to the Microsoft Documentation for details on how to resize the shadow storage area
