SBS 2003 BPA question Managed Recipient Policies

Hi to all,

I am planning a migration to sbs 2008 in the near future, still working on
choosing the hardware phase.

Just ran the SBS BPA today and got a warning that I can't seem to find an
answer for:

Managed Recipient Policies
The Mailbox Manager setting is enabled for one or more recipient policies.
As a result, the recipient policies will not be upgraded if you migrate to
Windows SBS 2008 and Exchange Server 2007.
I checked some blogs and tpis twaks,

Finally Answer for this problem that worked for me is
=============
If you have Exchange 2003 or Exchange 2000 policies that are BOTH E-mail Addresses and Mailbox Manager policies (they have both the Mailbox Manager Settings
(Policy) tab and the E-mail Addresses (Policy) tab), perform the following steps to remove the mailbox manager portion of the policy:

1. In Exchange System Manager, expand Recipients, and then select Recipient Policies.
2. Right-click the policy, and then select Change property pages.
3. Clear the Mailbox Manager Settings check box, and then click OK. Please reffere to above images.


How to check for duplicate/invalid SMTP addresses in recipient policies:

1. In Exchange System Manager, expand Recipients, and then select Recipient Policies.
2. Right-click the policy, and then select E-Mail Addresses (Policy) tab.
3. Inspect the SMTP Addresses for any that are unchecked. If you find any, place a check in the box or remove that address.
4. Inspect the SMTP Addresses for any that have an IP address. For instance, @192.168.1.1. If you find any, remove those addresses that contain an IP address.
5. Click OK.

Good Luck!!
