Folder on OneDrive deleted and not to be restored (Macbook Air MacOs Monterey)

[Anja Wysocki]

I received an email from no-reply@onedrive.com that a lot of my files have been deleted and to check the bin to restore it.

Neither in the bin nor under the restore option am I able to retrieve that folder.

I found a few files on the trash but the folder contained severeal gigabytes and hundreds of files...

How come it got deleted without me deleting?
