All,I'm working on aExchangemigration for my company, and I have a question regarding the impact ofdisabling the recipient policy for ALL users globally. Let me explain my situation to explain this better:We're migrating from an Exchange 5.5 environment to Exchange 2007 with the help of the QuestExchange Migration Wizard.A module of the Quest tool, called the Directory Sync, runs every 10 minutes and syncsemail addresses from Exchange5.5 to Active Directory (Exchange 2007). Our situation is that the default recipient policy in Exchange 2007 is set to firstname.lastname@domain.com.Unfortunately our 5.5 environment did not abide by addressing standards, so of 10k+ people, some have firstname.lastname,f.lastname, firstname_middlename_lastname, etc. Since theQuest directory sync runs every 10 minutes, it's setting Exchange 2007 users addresses to what they should be (their5.5 address). Butsince the recipient policy does not containall of the different iterations of email addresses, we are concerned that once we pull the Quest Directory Sync out of the mixfollowing the migration, Exchange will set the users addresses back to what the recipient policy states (firstname.lastname). We also CANNOT change users default reply to address, so we'd like to keep the address that the Directory Sync sets as the users primary (and secondary address).What we'd like to do is let the Quest directory sync run one last time, and using powershell, globally uncheck all objects from applying the recipient policy. What this will do is keep the default "reply to" address to what it is in 5.5 and prevents the Recipient Update from automatically update the defaultemail address based on the policy.Does this seem like a logical approach? Does anyone feel as though disabling the Recipient Policy on all objects will have an adverse affect on the2007environment such as GAL, OAB updates, etc? We understand that disabling the Recipient policy will cause us to have to manually maintain all addresses but is there anything else I'm missing?Thanks!

Hi, Please understand that we cannot upgrade an existing Exchange Server version 5.5 organization to Exchange Server 2007.We need to first migrate from the Exchange Srever5.5 organization to an Exchange Server 2003 or an Exchange 2000 Server.

The information on the migration is just background leading to my ultimate question.To clarify, I would like to know any potential impact of globally disabling the "Automatically update e-mail addresses based on e-mail address policy" to all Exchange 2007 mailboxes. I realize addresses will have to be inputted manually at creation if that box isn't checked, but I'm more worried about impact to the OAB, GAL or anything else once the "disable" powershell is run.Thanks!

Hi, I understand that you need to get the mailbox moved without changing their email address and will eventually fine tune the recipient policy to exclude these particular users. When a recipient has Automatically update e-mail addresses based on email address policy enabled, all primary e-mail addresses (default reply addresses) of e-mail address types will always be set from the e-mail address policy. This means that if you edit the primary address to be a different e-mail address, it will always revert back to the one specified in the e-mail address. Be sure that once you've corrected the email address policy filter or templates, you don't forget to re-enable the policy for these recipients or you will lose out on benefits of managing email addresses through email address policy benefits for the recipient in the future.
