I have had this problem for about a year now and have tried all the suggested fixes to no avail. I send messages and they are moved to the sent items folder but the recipient never gets the message. I have checked for corrupt folders deleted half my messages and this problem seems to continue. There is no rhyme or reason to the messages not being sent. PLEASE HELP1 person needs an answerI do too

Is that all msgs or just certain recepients?

It is just random messages some of them are at different companies and some are interoffice emails. It is hit or miss with the messages not sure where to go from here. I have tried all the fixes I can find online and nothing.

1: Remove your anti-virus program and reboot. Now do a custom installation and opt out of e-mail scanning when presented with the option. Why you don't need your anti-virus to scan your email http://thundercloud.net/infoave/tutorials/email-scanning/index.htm 2: Clean up OE. Move most of your messages out of the Inbox and then create new Outbox and Sent Items folders after you move any messages you wish to save to a local folder you create. Tools | Options | Maintenance | Store Folder will reveal the location of your Outlook Express files. Write the location down and navigate to it in Windows Explorer or, copy and paste it into Start | Run. In WinXP, Win2K & Win2K3, the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show Hidden Files and Folders under Start | Control Panel | Folder Options Icon | View, or in Windows Explorer | Tools | Folder Options | View. With OE closed, find the DBX files for the Outbox & Sent Items and delete them. New ones will be created automatically when you open OE. After you are done, follow up by compacting your folders manually while working *offline* and do it often. Click on Outlook Express at the top of the folder tree so no folders are open. Then: File | Work Offline (or double click Working Online in the Status Bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed. General precautions for Outlook Express: Do not archive mail in the Inbox or Sent Items. Create your own user defined folders and move the messages you wish to save to them. Empty Deleted Items folder daily. Although dbx files have a theoretical capacity of 2GB, I recommend about a 300MB max for less chance of corruption. Information about the maximum file size of the .dbx files that are used by Outlook Express: http://support.microsoft.com/?kbid=903095 Compact often as specified above. And backup often.

I have done this and the problem still exist!!!!!

If a message appears in Sent Items, and e-mail scanning is not an issue, then it was received by your ISP intact and the problem lies somewhere from that point on. You have eliminated OE as the culprit. If it is one recipient, the problem is on their end.Bruce Hagen ~ MS-MVP [Mail]
