Hey Mr. Davidson, I think I found a solution!!!
Actually, someone else found it...but, I haven't tried it yet because my email is still downloading off of my yahoo account, but, maybe you can try it out too...as I will later, when my account finishes downloading! From the simple logic of it, and being fairly technical myself, I think it will work! I can't wait to try after my email finishes downloading!
This is the solution, I found it in the Zimbra forum...at this link:
Copy or Batch Forward email messages between two accounts within Zimbra Desktop
Solution: I have two accounts... 1 Free Yahoo Email and 1 Yahoo Small Business Email. I am using the Zimbra Desktop to access both accounts. My goal was to move a few of the folders from my free account to my business account.
On the Zimbra Desktop, I went to Options >> Import/Export on my free account
I exported the folders I wanted (use advanced settings to select just mail if you don't need tasks, etc) one at a time. Then, I selected the business account and imported the files.
After a quick imap sync to Yahoo, everything was just how I wanted it!!!
