Does anyone know a way to change the from address for system messages like Quota's? I see you can customize quota messages but not change the from address... "Text Microsoft Exchange in the From field" http://technet.microsoft.com/en-us/library/bb232173.aspxI would really like to change this from the default "microsoftExchange& installation id @ domain in a different region than me.com"Thanks

Hi,The address of the generated system message is controlled by MicrosoftExchangeRecipientPrimarySMTPAddress parameter which you can view by running get-organizationconfig |fl in EMS.To change the default address, please execute the following Powershell command from the Exchange Management Shell:Set-OrganizationConfig -MicrosoftExchangeRecipientEmailAddressPolicyEnabled $falseSet-OrganizationConfig -MicrosoftExchangeRecipientPrimarySmtpAddress test@domain.comFor more information, please refer to the below article:http://technet.microsoft.com/en-us/library/bb430759.aspxThanksAllen

Looks like there was a bug in SP1 Rollup 7 that it displayed the GUID of the exchange installation and the original forest DNS name. After applying Rollup 8 the system messages are corrected for Unified message emails to the name of the person who left the voicemail or the phone number. I have not seen any quota messages yet, but I believe they should now just say Microsoft Exchange instead of what I was getting.
