We are experiencing errors on our exchange server.

Note: there are many of the 1022 errors for various users throughout the organization.  The 9791 errors show up intermittently as do the 623 errors.  The errors began today around 2pm and are continuous until now (4pm).  Users are getting error messages in their mailboxes and Outlook client performance is very slow to unresponsive at times causing some to have to restart their Outlook application to full reboots of their desktops.

What might the issue be??
