POP-IMAP-SMTP Settings

Exchange - POP/IMAP/SMTP Settings

** Important Notes **

1) Before the settings below can be utilized, your faculty / staff e-mail account must be activated in Exchange.  See the www.clarion.edu/computing/exchange site for details.

2) POP/IMAP/SMTP settings are not used with a standard on-campus Outlook configuration.  These alternative services are only needed with non-outlook clients (ex. MacMail) or with off-campus e-mail client configurations.  For most off-campus access, we suggest that you consider the Outlook Web App (OWA) interface; see our Outlook Web App page for more information.


For on-campus / non-Outlook or off-campus mail clients/devices, these are the POP and IMAP settings.  Note: You must contact Computing Services to have POP or IMAP enabled on your account before you can use these services.
