Hi,
after export and disable mailbox on source (old) exchange 2007 server, I import pst file to new Exchange 2013 server.
But users at outlook - use response or auto substitution, and get massage after sending mail to the migrated user.
IMCEAEX-_O=TECHNO_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=TESTUSER3@domain.local
#550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##
and if thay inpute full email address - massage send with no errors.
It like, outlook use cache. I try disable disable caching mode of outlook - but without success.
How I can fix it, the best solution?
