Hello all, Recently - I have been getting reports that messages sent to random different DL's are not being delivered to all members of the DL. The members are all internal employees - no external addresses. I can run a message trace in the Admin Console, and it shows the messages being delivered successfully, but when searching the users' maibox (including deleted item retention and PST's) I can not find the messages. Generally this type of issue can be chalked up to the recipient accidentally deleting it or moving it - but not in these cases. On top of this, we have an e-mail archival service that keeps a copy of all e-mails sent to or received by a user (Frontbridge Continuity Services). Even in this utility, the messages have not been copied to the archive which leads me to believe the message was not delivered. So - any ideas why Message Tracker shows the message as having been delivered to the store but never actually showing up in the recipients mailbox? Oh - I had this occur once last week when a message was sent to about 30 people (no DL) and all but one of our employees received it. Very confused and I welcome your input. Regards, Chris
