#Exchange #Exchange2010 custom KBs

here is my KBs for the last 2 weeks:

KB1: Error when you try to move a user’s mailbox from Exchange 2003 database to another server or another database : The information store could not be opened. The MAPI provider failed. MAPI 1.0 ID no: 8004011d-0289-00000000 Error: -2147221231

Cause/Solution: the user is hidden from being displayed in the GAL, to move the use unhide the user from the GAL and try the move operation.

KB2: you create a new user the following error appear:

Failed to generate email addresses based on template “CCMAIL: at MEXDOMAIN01”. Additional message: “Failed to find the address type object in Active Directory for address type “CCMAIL:AMD64″.”.

Failed to generate email addresses based on template “MS:PRODUCTOSF/MEXDOMAIN0”. Additional message: “Failed to find the address type object in Active Directory for address type “MS:AMD64″.”.


To resolve this issue you need to edit your policy in Active Directory using ADSIEdit tool and delete disabledGatewayProxy entries of MS and CCMAIL

1. On your DC, open adsiedit.msc (Support Tools must be installed in order to be able to add ADSIEdit)

2. Connect to Configuration Naming Context

3. Browse to Services –> Microsoft Exchange –> YOURORGANIZATON –> Recipient Policies

4. On the right click Properties of Default Policy

5. Click Show only objects with entries

6. Find disabledGatewayProxy

7. Edit its content




KB3: users moved from Exchange 2003 to Exchange 2010 SP1, or after applying Exchange 2010 SP1 cannot update distribution group membership with error

Changes to the distribution list membership cannot be saved. You do not have sufficient permission to peform this operation on this object


you need to make changes as per this KB:


also note that being Exchange administrator doesn’t mean that you will be able to manage the group, in Exchange 2010 SP1 the code checks if the user creating the change is the owner of the group or not, in the RTM version that wasn’t there, you can modify the groups using powershell to use BypassSecurityGroupManagerCheck (pre-SP1 behavior).

KB4: cannot open Exfolders on Exchange 2010 with error Exception: The Active directory user wasn’f found.

Solution: Open adsiedit and check if there any objects in CN=Servers,CN=Fist administrative group,CN=Administrative Groups,CN=<Exchange Org Name>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=local. Is the container “CN=Servers” empty, then delete it
