Hello,
I was wondering if there is any way to have sub folders in Roundcube?
Yes there is:
Go to settings - Folders - New Folder (give it a name like Folder) then make one more new folder thats called Folder.Sub-Folder
Depending on you sever it may be a / not a .
This works fine however if you make a subfolder of inbox it is not show under inbox on the personal settings -> folders page, but it is on the main e-mail screen. Also you can make a subfolder under a folder you have created by just clicking on the folder name and creating a new folder. Why clicking on Inbox allow a subfolder to be created under it?
