I have disabled a mailbox on exchange and added its email address as an alias for another mailbox. The alias is working fine when sending email from an external domain, but it isn't working when sending from the same domain. It returns the error:
IMCEAEX-_o=Contoso+20Corp_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=Magalhaes+20B+2E+20Souza+2C+20Mariana9ca@contosocorp.com
Remote Server returned '550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found'
The email address smtp:[email protected]
is showing on the mailbox's addresses.
How can I fix this?
