There are multiple recipients matching the identity "Paul smite". Please specify a unique value.


i cannot set up a mailbox rule to bcc messages from one mailbox to another user

we have multiple email accounts for diffrent users with diffrent domain names

is there anyway to bypass the above email

for example we have


Chris bowden   Chris@mancity.com

Chris bowden   Chris@mcfc.com

is there anyway around this with the multiple mail boxes name

Change the display name in the Exchange admin center or in Active Directory Users and Computers so that the name doesn't conflict with an existing mailbox or mail contact.

Further you can refer this article:

yes but then it will show diffrently to external users
Andy MIT Systems ManagerCommented:
What if you create a contact for the required mail address under a different name.

That wouldn't affect external users and should allow you to route the email accordingly.

Chris,
Create the rule(s) in powershell and specify email addresses or aliases as opposed to DisplayNames

In other words when an email comes in to chris@bowdencctv.co.uk you want it forwarded to mark@bowdencctv.co.uk?
FOXActive Directory/Exchange EngineerCommented:
Chris- Use the below powershell command to set up forwarding for the incoming mails from one mailbox to the next.  It will keep a copy in the original mailbox as well.

Set-Mailbox -Identity "chris@bowdencctv.co.uk" -DeliverToMailboxAndForward $true -ForwardingSMTPAddress "mark@bowdencctv.co.uk"
