The Mailbox Replication Proxy (MRSProxy) service is installed on every Exchange 2010 Client Access server. MRSProxy helps to facilitate cross-forest move requests and runs on the remote forest’s Exchange 2010 Client Access server. However, by default, MRSProxy is disabled
If we are going to do a Cross forest move mailbox ,
Source Forest Exchange 2010 Client Access Server should have MRS proxy enabled to facilitate the Remote move
If the Source Forest CAS servers are in a Cas Array
All Client Access servers in the Network Load Balancing (NLB) array must have MRSProxy started
Otherwise you will end up with an Error
To Enable MRS Proxy
Set-WebServicesVirtualDirectory -Identity "EWS (Default Web Site)" -MRSProxyEnabled $true
To Increase Time Out
Browse to the Below Location
C:\Program FIles\Microsoft\Exchange Server\v14\ClientAccess\exchweb\ews
Open Web.Config Using Notepad
Browse to the bottom or Find Mrsproxy , Get to the Below Location
By default It will be “00:01:00” , Where if you feel MRS proxy gets to a idle time out we can increase that 20:00:00 minutes maximum
Take a Copy of the Web.config File , you can change to “00:20:00” minutes as below
Save And Close it
and Do a iisreset in your command prompt

Hi,
I think this “Set-WebServicesVirtualDirectory -Identity “EWS (Default Web Site)” -MRSProxyEnabled $true” works only on Exchange with SP2 installed, so for Release or SP1 web.config must be edited.
Best regards!
Yep, Thanks for the Useful info . Ivan
I have few questions to clarify with email migration from exchange 2010 to office 365
1. For hybrid setup in exchange 2010 sp2. When I add my office 365 forest to my exchange server its prompts an error and it seems error related to SP, I guess I need to upgrade to SP 3. Now my concern is during this upgrade there will be an upgrade for AD scheme which is more serious thing need to note down , is there any way to skip this ad schema update and if not is there any workaround solutions?
2. Another method: Let say if I am not going to upgrade and not going to implement hybrid, is there any other method to move my mail box from on- premise to exchange online (office 365) by batch. Notice cut-over migration will migrate all the mail box but we need to do batch by batch
Please advice
How much mailboxes we are talking about ?
Thanks for a great manual.

For Exchange 2007 sp3 while running command
A Parameter cannot be found that matches parameter name ‘MRSProxyEnabled’
MRS Proxy is not available until Exchange 2010. It order to do a mailbox migration from Exchange 2007 to any newer version of Exchange you have to jump some hoops. You can find a solid method at the link below:
