Hi. I'm migrate to Exchange 2013. I moved mailbox, moved public folders ( 20 folders in one pf-mailbox). I can see structure public folders, but when i send mail to public folders, i see error: this recepient not found

Формирующий сервер: EXCHANGE2013.polikomm.local

Remote Server returned '550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found'
