Its the address cache, so don't reply to messages that contain this account if its an incomming.<br />
<br />
Don't make mistakes, a wrong address is still remembered.<br />
<br />
Could be someone playing a practical joke, had this once before - &quot;&nbsp;I just don't know where this is coming from - I've never seen this address before!!&quot;<br />
<br />
I found a good description with the differences here:<br />

<div>
Apache: those sound like good tips. I'll see if there are any 3rd party apps and re-create the profile from scratch.<br />
<br />
Also of note, this isnt solely related to user1... user3 and user4 also have this same issue emailing user2.

<div>
does activesync ring any bells?<br />

</div>


<div>
ActiveSync or any other mail/calendar/contact app is not installed. Should it ring any other bells?<br />
<br />
I've recreated the Outlook profile of user1 for the test. we'll see how it goes over the next couple of days.
</div>


<div>
I've been monitoring it daily, with no trouble so far. <br />
<br />
new bounces have occurred upto 10 days after a previous change (even though mail sent to the user2 address has worked fine during that 10 days)... I'm just waiting a little longer to see how it pans out...
</div>


<div>
Looks like re-creating the Outlook profile did the trick.<br />
<br />
The other items you suggested where good tips also.<br />
<br />
Thanks!

looks like I spoke to soon, the problem has re-occured.<br />

Hello,<br />
<br />
We have a couple of Outlooks that continually populate bad email addresses in the cache/nickname (NK2) file.<br />
<br />
It only appears to affect one recipient, but after a few days the address in the cache ends up pointing to a user that doesnt exist.<br />
<br />
For example; User1 sends to user2, putting in the address using the 'check name' feature, all is well. Next time user1 tries to send to user2, they use the cached address and the email bounces due to the recipient not existing on the exchange server.<br />
<br />
Looking into the details of the bounced mail, we can see the path to the user reference is bad<br />
<br />
/O=THEDOMAIN/OU=FIRST ADMINISTRATIVE GROUP/CN=RECIPIENTS/CN=USE<wbr />R262156485<wbr /><br />
<br />
There never was a user262156485, it should obviously point to user2... I have no idea where it picks up this reference.<br />
<br />
I've tried deleting the bad reference out of the NK2 through Outlook, and with various tools. I've tried deleting the whole NK2, but after a few emails the bad reference comes back.<br />
<br />
So my question is; how can I get rid of the reference so that I can ensure that it doesnt come back?<br />
