Hi, I have created a mailbox for journaling recipient, and this command: Set-Mailbox journalingmailbox@domain.com -AcceptMessagesOnlyFromSendersOrMembers 'Microsoft Exchange' -RequireSenderAuthenticationEnabled $true is throwing this error: There are multiple recipients matching the identity "Microsoft Exchange". Please specify a unique value. I am not able to find how to check "Microsoft Exchange" duplicity. Thanks and Regards, Laeeq Qazi|Team Lead(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com

Hi, A page directed me to this page: Understanding the Microsoft Exchange Recipient and it seems that its better to get the Primary Smtp Adress of "Microsoft Exchange" recipient using "Get-OrganizationConfig" command, so that it can be used in Set-Mailbox command in O.P in place of "Microsfot Exchange" value. I did it and it resolved the error. Regards, Laeeq Qazi|Team Lead(Exchange + Sharepoint + BES + DynamicsCRM) www.HostingController.com
