I don't know what you are trying to do. I still use Outlook 2000 since my email is still via MSN and it's protocol isn't supported in Mozilla.
Rather than "what does this button do?", try to ask "How do I ???"
I recently switched from OE to Thnderbird 0.7.
There is a window under accounts that is a one line entry listed as special account.
It has the entry "no one on local folder".
The help button does not activate a window to explain
I have looked in T-Bird help with no results'
Can anyone tell me what this window does. Or how to use it.
Thanks for your reply
