Try this, as it worked for me recently with Outlook 2003 SP3. Make sure you
have a copy of your Outlook parameters in using Exchange as this procedure
deletes the currently existing Outlook/Exchange connection information!
First of all, I'd like to explain that Outlook 2003 supports junk e-mail
filtering for the following account types:
1. Microsoft Exchange Server e-mail accounts in Cached Exchange Mode
2. Microsoft Exchange Server e-mail accounts when mail is delivered to a
Personal Folders file (PST file)
3. HTTP accounts
4. POP accounts
5. MSN/Hotmail accounts
The following account types are not supported for Outlook junk e-mail
filtering:
- Microsoft Exchange Server e-mail accounts in Online (MDB) mode
- Third-party MAPI providers
- IMAP accounts
If you're currently in one of above supported scenario but Junk Email
feature is still not working, I recommend you perform the following steps and
see whether it helps.
Step 1: Detect and Repair
