You can certainly set-up the account in Thunderbird with the settings you used with Entourage. https://support.mozilla.org/en-US/kb/manual-account-configuration

I kept getting an error while submitting and was instructed by Mozilla to "try again in a few minutes". This is the result of those few tries. I apologize for the multiple posts. I received an error message that it didn't post.

Also, your link was helpful, but I'm still getting an error finding my old information in the database.

I'm still getting an error finding my old information in the database.

I don't understand this. You said you do have the server settings from your Entourage installation. What's missing?

The drop down options that I'm given in TB under "ports" does not match the numbers I have from Entourage, and I'm not able to enter them manually. I tried doing the auto-search and that doesn't work as well. I suppose I'm asking if there are other options/trouble shooting paths to go down?

Thanks again for your help. I do appreciate it.

Can you post the settings you used with Entourage?
