A problem was discovered with Outlook Web App failing to display messages. This seems to only be a problem displaying message in Outlook Web App and does not impact mail flow. ITI Systems is investigating the problem.

ITI Systems has received reports that email delivery is slow for some users. We are rebooting an Exchange host which appears to be sluggish.
Impact: Users whose email is hosted on this system may experience slowness as the databases hosted on muexch05 are activated on other nodes during the reboot process.
Affected Applications: Exchange mail
A server hosting Exchange 2016 mailbox databases had a failure and rebooted. ITI Systems is investigating the cause of the failure.
Impact: Minimal impact. The mailbox databases failed over on surviving peers
Affected Applications: Exchange 2016
Due to several compromised accounts sending SPAM and phishing emails targeting unknown users at AOL and Yahoo, Marshall.edu has earned a bad sender reputation with Yahoo’s sender reputation service. This service forces all emails coming from marshall.edu to be deferred when sending emails to AOL.com and Yahoo.com. There is no way to request a delisting but Yahoo claims that “typically” the listing should only last for 4 hours unless there are continued reports. The Systems team will be closely monitoring our Exchange queues and will update the ITServiceStatus web site once the ban has lifted.
Affected Applications: -----
In an effort to improve recipient verification on mass mailings coming in to the University email systems, the ITI Systems team has made modifications to our Barracuda_Recipient_Verification and Barracuda receive connectors in Exchange. These changes have eliminated the restrictions on the number of concurrent recipient verification requests. Please contact the service desk and report any undesired issues with email due to this change.
