What if I need to send more emails?
Creighton’s Microsoft 365 email accounts are intended to be used for interpersonal communications. The account should not be used to send bulk email. People with a business need to routinely send bulk email or more messages than their default email limit can work with a commercial bulk mail service or create a listserv at list.creighton.edu. For more information on mailman listservs visit our myIT knowledge base.
Why are we changing the default limits
Our goals are to ensure the continual operation of Creighton’s email system, reduce abuse of the @creighton.edu email accounts, and be a good neighbor to other organizations. Microsoft has recently reduced the messages per day to reduce phishing messages that frequently result in malicious senders using compromised accounts to email the campus community. Most Creighton Microsoft 365 accounts send only a handful of messages per day.
Our intention is to introduce reasonable sending limits for people who don’t normally send a lot of mail without preventing legitimate campus communication.
