Cannot copy mail from Local Folders to IMAP main account with Thunderbird
I'm very puzzled by the behaviour I'm seeing with Thunderbird when trying to copy some folders, or even single emails, from Local Folders to the main IMAP account via drag and drop. I had this working fine earlier with an IMAP account I have at virginmedia.com - folders, nested subfolders and the emails within all copied fine. With a Thunderbird account set up to use Zoho via IMAP, though, either nothing happens at all (most of the time), as if the target folder is simply locked, or one folder only is copied, without any content. Why might this be, and is there a way I can get this to work?
On a more general note, assuming I do get this to work, will the nested folder structure I have be visible to me via the Zoho Mail web application? That is the aim, to allow people to move away from the desktop clients to accessing their mai via the web client.
