Unable to send email large groups of recipients

Issue/Question

I am trying to send an email to a large list of recipients and receive an error.

This message could not be sent. Try sending the message again later, or contact your network administrator. The client operation failed. Error is [0x80004005-0x80004005-0x000501].

Environment

  • Microsoft Exchange/O365 (College email)

Resolution

Information on the proper use of email can be found within the Information Security and Systems Integrity Policy.  Additional information can be found below.

  • Staff can send emails 400 recipients within a 24 hour period.  
  • If you need to send to more than 400 recipients on a regular basis we advise that you review the College's guidelines on bulk email to be sure all emails are meeting both college and legal requirements.
  • Bulk mailing to students and outside e-mail addresses MUST conform to the Federal CAN-SPAM Act of 2003 which REQUIRES the sender to provide recipients an opportunity to decline from receiving future messages.  If an individual has opted out from receiving unsolicited bulk  e-mail from Macomb (even if they initiated it!) and is sent another e-mail message covered by this law, then the College can be fined up to $750 per unlawful message.
  • Several departments pay to use a 3rd party service called Constant Contact to communicate to large groups of recipients.  Their information can be found here.
