To check if your Microsoft Exchange credentials are correct:
If you are using Office 365, you can go to this website:
(if you are using your own exchange server, replace "outlook.office365.com" with your exchange server's address)
and enter your username and password. Username is often, but not always, your company email address, ex: firstname.lastname@example.org
If you were able to log into your Exchange account, login to WeOpportunity.
Click My Settings on the top right hand corner
Then select Mail Server Settings (This Tab is called Autosync Settings on V6 or later Systems)
The Mail Server Type will be Microsoft Exchange
Then Enter you Microsoft Exchange user name and password.
Must sure to log out then back in for the changes to take effect.
