This sounds like a Mailbox size restriction issue. You need make sure the emails that are failing are not enlarging the mailbox size to beyond the maximum allowed. Ask the recipient to do some clean up of the mailbox to free up space. HTH.

Some users can send to this account. Those that cannot receive the error below. The account is not a DL and not limited. Any thoughts. The user just transferred from another office - email address stayed the same, Display name and group assignments are different. Those that can send to her email are from her old office. All systems are in the same domain. tia greg error: Long Pamela 11/30/2005 9:33 AM The content length of the message is too long for the recipient to take delivery The MTS-ID of the original message is: c=US;a=DMS;l=FSTYMX48-051130153313Z-408692 MSEXCH:MSExchangeMTA:SITENAME:FSTYMX52
