How to recover the trust between parent and child domain if Access is denied between them happened

that's becasue the TDO ( trusted domain object) has been corrupted as i have been informed once from Microsoft

Busbar, one of the Experts out there, blog that wonderfull post and i wanted to share it with you

when you send digitally signed message through exchange 2007 edge server, the message cannot be verfied on the destination

as the address say, when you send digitally signed message through exchange 2007 edge server, the message cannot be verfied on the destination, that has been raised for a while, by escalation case by myself, and after further investigation on that subject working with the support team whom they made a lot of work ( and me as well) i managed to fix that, it was a bug !

a bug in which when you send email from outlook in HTML format, it will reach the destination in unverfied format, and a red arrow in the front of head of the message, and that's only happen when you send HTML messages with attachement in it, that's also mean when you send HTML messages in HTML format without attachement it WILL be verified, so the problem came in sending attachement

sawing saw, i disabled the attachement filter on the edge servers, and voila ! it woked fine..

i reported that to Microsoft and hopefully a fix will be available on rollup update 2 for exchange SP1

btw, you still can use remove-attachementfilterentry cmdlet but i didn't tested that actually

Good luck with your implementation
