Frequently Asked Questions About Email

  • What is the format of LAW email addresses? All faculty and staff receive firstname.lastname addresses that deliver to their Exchange mailbox, e.g., I 
  • Why don't we just use Gmail? The university has an agreement with Microsoft to use Office 365 for our email service. The breadth of needs of the university and the health system, especially regarding security and privacy, made this the right choice.
  • Are there recommendations for mailbox size? We recommend no more than 10,000 messages in any one folder. Also, you should delete outgoing and received messages with large attachments. Email is not the appropriate place to archive files. Microsoft recommends that your online mailbox be 10GB or less for best performance. If you have more mail than that, older mail can be moved to an archive.
  • Are there limits to the size of the email messages I can send and receive? There is a 25MB size limit for any message coming in from the Internet and sent from Exchange. In practice, messages sent over the Internet will have a lower limit because attachments need to be encoded for transport (usually limiting the message size to less than 20MB). It bears noting that many, if not most, email systems impose a size limit similar to this (Gmail imposes a 25MB limit as well). If you need to share files that are larger, we can recommend better ways, such as Duke Box. Please contact the help desk for assistance (613-7072,
