I am able to receive messages on my IMac using Outlook but am unable to send.  I've had no trouble in the past but began receiving the following messages today.


5.7.8 Bad username or password (Authentication failed).

Authentication failed because Outlook doesn't support any of the available authentication methods.



I am able to send messages using this account on my IPhone and IPad so the IMac is the only place I am having issues.  Any advice?

iMac, Mac OS X (10.6.8)
