I deleted an ex-salesperson's account but the manager still would like to continue receiving future emails. So I deleted his account and added the email address under the manager's mailbox property in exchange. See the sample image for the dialogue box I am referring to.
However, when I tried sending a test email to the salesperson email address, Exchange kept giving this response:
#550 5.1.1 RESOLVER.ADR.ExRecipNotFou
nd; not found ##
Any idea why this is and how to resolve it?
Thanks in advance.
