554 One or more of the sender or recipients in your email are invalid and not accepted.'

Hello,

Emails are being returned undelivered to us from a particular recipient (who happens to be a bank, if that matters). All other mail, to our knowledge is functioning properly and being delivered without an issue.

The email was switched from an in-house Exchange server to an Office 365 hosted Exchange server in August 2013. On a side note, we tried emailing them from another domain/account hosted on Office 365 as well and it bounced back with the same error code)

Tried with 3 different email accounts that were not Office 365 related and the same thing happened. Appears to have been an issue with the bank mail server.

Thanks for your assistance.
