Hi All, One of my users deleted a Public Folder which i was able to recover using PFDAVAdmin. However i then mail enabled the Public Folder and i tested mailing it by emailing a test from an external machine on the internet, this worked fine without any issues. However when my users try emailing the address internally exchange gives me this NDR IMCEAEX-_O=FIRST+20ORGANIZATION_OU=EXCHANGE+20ADMINISTRATIVE+20GROUP+20+28FYDIBOHF23SPDLT+29_CN=RECIPIENTS_CN=ENQUIRIES6CF8BEA94AC24C4A17463F87F37E42D0E55F9E@<MY COMPANY>.local the only thing i can see that links the Public folder to this is the display name in the global address list, i look in the public folder management and i can see the correct name in there. i have tried deleting the cached address that the users have previously used and als downloading the glabal address list after the changes but the error is still at large. i then tried emailing the account from OWA and again i still get the NDR, it seems any internal communication to this address it NDR's but external communication works. tried looking through google but cannot find anything that has helped yet. #550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found ##

it looks like i have got 2 identical emails in my GAL so i am going to attempt rebuilding it and see if that rectifies the problem with this email address. any tips on how i rebuild the GAL on Exchange 2007 (my powershell is basic!!)

Hi Carlos, You could follow this article to rebuilt or update GAL. http://www.msexchange.org/articles_tutorials/exchange-server-2007/management-administration/address-lists-exchange-2007-part1.html After you rebuilt or update GAL, don’t forget: 1. Restarting Microsoft Exchange File Distribution services on CAS . 2. Updating OAB at Outlook client side.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi Jerome, i found a little workaround which seems to have worked for me. I found the "original" active directory object with the address that i want to use and renamed everything by appending a number to the end of the name, the email address associated with the object etc. i then was able to mail enable the public folder and when the GAL rebuild itself periodically it cleared out the "original" object where i renamed the attributes. i hope that makes sense, but thank you for the article i will try that next time i have to restore a mail enabled public folder!! thanks Carlos
