Which version of Exchange are you running? please let us know yur environment in brief. How many ex servers? Any Spam Filter/Smart Host? Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

are they being removed from exchange or ending up in the deleted items folder?Check for any AV/Spam software that may be filtering, also, as Vinod suggestsed, what does your environment look like? When did the problem start? Has it always done this? Did you just complete a migration?SF - MCITP:EMA, MCTS

we have Scan Mail installed on both frontend and backend server , but in tracking its showing mail delieverd locally to store and also give the receipent mailbox name, but mail is not delieverd either in inbox or deleted Items,we are not able to find where the mails goesour environment isThree frontend server, three two nodes clusters

Hi, Please check your Scan Mail, if there has any rules or filters. Wed better to check the scan log to see if any message has been deleted. Also please check if you have proper configured for your Scan Mail,you can check it with the following article. File-Level Antivirus Scanning on Exchange 2007 http://technet.microsoft.com/en-us/library/bb332342.aspx Besides, what do you mean message header?Subject? Where do you check the message header. Please try to post it here. Regards, Xiu

hi,we have Exchange 2003 Environment, we disabled the Scan mail service from the nodes ,but still some mails is not delieverd to the mailbox, and in tracking it shows delievered also the message Header means the message ID : <FE163DD68948464EB1E6946823DF579E2FA1DD>@server name.com

In next step I would play with outlook server and client side rules... Take backup of all existing outlook rules, delete those and then follow below article to delete any corrupt/hidden/stale rules with MFCMapi and test the issue.

hi Amit,my problem is that it is not happening with all mails but some of the mails , like if i sent this mail through OWA or Mapi Account , its delieverd but if i sent mail this from Pop3 client the same mail , it shows delieverd to all the receipients ,but its not delieverd to user mailbox, i add the same in To in that mail , i also not received the same, and the message ID is too large as compare to other mails.please help me in this

Is the message showing up in OWA? I'm curious if it is client side or server side.Are you using Outlook Cache mode? Is this happening for every user in the organziation or some select users? When did this problem begin, were there any changes to the environment, or a Workstation update etc? SF - MCITP:EMA, MCTS

message is not showing in OWA also and it is happening from last two or three days, some mails which are forwared or reply thats are not delieverd, it is not happening to all user , some of the users in our organisation

Hi,Please try to clarify with what pop3 client the mail will be dropped.If we create a new email in pop3 client and then send it,wil the issue occur?Besidesplease try to find where these email sent from,external exchange Server?Or other Message system?Regards,Xiu

In the last few days what changed to your environment? These users didn't install a third party app or tool bar on their systems have they? What happens if they go to another workstation that works and tries? Does this problem exist for these users if POP3 isn't being used?SF - MCITP:EMA, MCTS

hi,it is happening on only some of the mails , not the workstation problem. if you send the same mail to another user ,when the user reply or forward of that mail , that mail is not delieverd . i search it and there is one solution is suggest that it happens if you reply or forward mails from mail comes from rules.i dont know it is happening on some of the mail not everyone

Hi,That mail comes from external message system? What is the message system?Also please try to get message tracking log to see when the email be dropped.Improved Message Tracking Features in Exchange Server 2003 http://support.microsoft.com/kb/823864Message tracking event IDs in Exchange Server 2003http://support.microsoft.com/kb/821905Regards,Xiu
