While faculty/staff can always read and send e-mail using Outlook on-campus, or Outlook Web Access or Virtual Workspace from off-campus, faculty/staff can also use an IMAP e-mail client to access their mailboxes.  Faculty/staff using IMAP for e-mail will not have access to calendaring, task management, and other collaborative capabilities while using the IMAP client. 

POP e-mail clients are still an option, but POP has been deprecated in Towson's e-mail environment, and is only enabled on a mailbox by request.  OTS strongly recommends not enabling POP since a simple mistake can mean that all email is removed from the mailbox.  OTS has no ability to restore mailboxes in Office 365, so it will be necessary for any user to use Recover Deleted Items on their own to recover deleted mail.  Before using an e-mail application, it is important to understand the differences between IMAP and POP:

Because there are many different e-mail applications and most applications have step-by-step configuration wizards, OTS is providing the important configuration settings every e-mail application will require:

Incoming e-mail server settings (POP or IMAP):

  • Server:
  • Use SSL (secure connection) on port 993 (for IMAP) or port 995 (for POP)
  • Username:  full e-mail address  (e.g.,
  • Password:  NetID password

Outgoing e-mail server settings:

  • Server:
  • Use TLS (secure connection) on port 587 for outgoing server (also known as SMTP).  Some clients (such as Windows Mail and Outlook Express) may not have an option for using TLS, but instead only have an option for SSL -- in these cases, choose SSL.  When presented with both options, choose TLS.
  • The outgoing server requires authentication
  • Username and password should be the same as for the incoming e-mail server configuration.
