ULM's email system is based on Zimbra mail and can be accessed from any computer that has a web browser and internet access.
Access to the email system can be obtained through the ULM Portal system at https://my.ulm.edu
ULM faculty/staff email resides under the Spock email account structure, ex: firstname.lastname@example.org.
In the case of a portal outage, the mail system can also be accessed directly at https://myemployeemail.ulm.edu
If you are looking for missing messages, check your SPAM/Quarantine area. This is available in the myULM portal under "Campus Systems" as appropriate for the user type.
