Hi All !As usual, if I have missed any earlier posts regarding this issue please let me know.We are about to implement Office Communication Server 2007 R2 ("OCS") in a multi forest scanario, and according to this doc http://download.microsoft.com/download/0/e/0/0e00ebbb-d11e-49e2-8785-93467b057206/OCS_MultipleForestDeployment.doc the use of MIIS, will be able to accomplish this (provisioning dsiabled users from one "non-ocs"-forrest into another "ocs-existing"-forrest. The above article reference both how to use all of the OCS 2007 R2 supplied files "into" MIIS (such as rules extension file; Lcssync.dll, schema extension file; Lcsmvschema.xml, and so on..). So with that as background, I'd really like to know if there are anyone who has experience using FIM 2010 and OCS 2007 R2, and if you do, can you please help me out ? TIA, Anders B

I guess that Ahmad Abdel-wahed would like a more specific technical request...so here it goes (with the info above as a background):- Can I sync relevant info (as to regards to OCS 2007 R2) from one AD forest to another AD forest with FIM 2010 ?/Anders B
