Interesting. Backslash escaping the spaces, or using either single or double quotes works for -other- zmmailbox commands (like gfg), but not for search, it appears.
[zimbra@nepenthes ~]$ zmmailbox -z -m bevan gfg /Schooner Room
usage:
getFolderGrant(gfg) [opts] {folder-path}
-v/--verbose verbose output
[zimbra@nepenthes ~]$ zmmailbox -z -m bevan gfg /Schooner\ Room

A little fiddling says that the follwing may actually work (I'd need confirmation, since I currently don't have any data in these folders to search for...)
zmmailbox -z -m USER search 'in:"/A Folder" 1'
Oddly, the following definitely does not work:
zmmailbox -z -m USER search "in:'/A Folder' 1"  |
