Has anyone been able to access webmail via the email client? I can't for the life of me figure this out. It was so simple on Chattermail.

I have entered the following:
selected Exchange (EAS)
email address - first.last@xxx.com where xxx is my company name
incoming mail server - https://webmail.xxx.com
domain name - xxx.com
user name - first.last
password

I can get in through the web on the Pre, just can't figure out the settings for the email client.
