The outlook is sending odd email by its own automatically without users knowledge and user realizes this when he gets a bounce back error message from server...

Scan the computer for virus/malware

Likely either a mail bot on his PC sending spam from his computer (AVG or similar malware program can remove this), or a mail bot elsewhere using mail address spoofing (Pretends to be from his mail address) so he gets the bounce even though he never sent anything.

HI
can anyone comeup with any quick solution as this is my Ceos machine and mail address belongs to him so i need to resolve it asap ..
Thanx

If you don't have one installed, download a malware scanner like AVG, run a scan on the PC, if he has a mail bot on his PC that will remove it. If it is not on his pc and he is getting bounced mails due to a mail spoofing, as far as I knowm the best thing you can do is set up an outlook rule to delete them on receipt so he doesn't see them.

Hi
I think we can uncheck this issue as we have trend micro installed on out all servers and pc .
About outlook rule is something i can say not a solution as this issue is something more than i can ignore.
please advice some permenant solution will appreciate.
Thanks

If it is mail spoofing, the only working solution I am aware of is SPF (Sender Policy Framework), you'd have to add some information to your "Zone File", either yourself or your Domain provider.  You'll find details on the links below.

But even this is not foolproof as it depends on the server receiving the mail to support it, unfortunately thats the best there is at the moment.  there si no permanent foolproof solution available as yet.

ok
I am sure its because of spyware as i think i am looking in past when they were used to store password as well so think so this might be the case as well
