Getting this error repeatedly in Event Viewer and cannot find anything on why or how to fix.

Microsoft.Exchange.Management.ControlPanel.RegionalSettingsNotConfiguredException: We couldn't process the request because the user 'domain.com/Microsoft Exchange System Objects/Monitoring Mailboxes/HealthMailboxdb4adc85620b496ab796c0a2fdb812d7' hasn't signed in to Outlook Web App and selected a language and a time zone. Ask the user to do this, or, if you are a member of the built-in Organization Management or Help Desk role group, you can use Window PowerShell to select a language and time zone for them.
I ran get-mailbox -monitoring and all came back with no errors.
