Hi - I was using Zimbra Mobile web client on my Kindle Fire and it was working great. Then my browser failed to launch and I contacted Kindle support. They had me "clear data" from my browser application settings. I then was able to launch a browser and get to the Zimbra log in screen. I tried multiple times to log in using my username and password. I tried multiple versions i.e. Mobile, HTML, Ajax, etc. and still I get an error that my username and password is wrong. I shut down the unit and restarted it. I again cleared the data and cache in browser. I still get the error message. I logged into Zimbra from my PC web browser and my uname and password worked fine. Any suggestions? I loved being able to View my Zimbra email on my Kindle Fire.
