Hi, In my organization some problems appear with a combination SpamBayes-Outlook2003-Exchange5.5. In fact, when these users wanted to join a file in a mail, all files were available.. except zip files !! It was a special spambayes problem, because only computers with spam-bayes were touched. Solution found : install a new profile with the same parameters as before. Launch it. Close it. Re-launch the first profile. Zip files are now available to be joined. Crazy, don't you think ? Have you already undergone a problem like this ? Have you got an other solution to go over it ? Thanks a lot. Steven, from France
