Checking the underlying REST calls brought up this:

"failure" : "Database upgrade required",
"message": "Mail database is not ready"
}
}
The IBM Verse On-Premises 1.0 Administrator Documentation clarifies the required steps to prepare a mail file for VOP. Besides some new views, VOP also requires that Folder references are enabled for the mail file. A convert -m task rsolved the issue quickly for me.

- add additional views
- enable full text index
- enable folder references
