I have an Exchange 2007 SCC installation full updated and i have a problem with a specific internal account trying to send email to a specific external account . When try to send from this internal account i get an email back from exchange with the error :
This message has too many recipients. Microsoft Exchange will not try to
redeliver this message for you. Please try resending with fewer recipients, or
provide the following diagnostic text to your system administrator.
550 5.5.3 RESOLVER.ADR.RecipLimit; too many recipients ##
The thing is that i dont send to multiple recipients but only to the one external account.
Another strange thing is that if i send from another internal account to the same external account it send it successfully . I try also from OWA and i get tha same error.
Any ideas ?
