During an Exchange 2007 mailbox migration, the EMWMTA.log file shows the following error, and no mail is being processed:
"CMBMConn::CheckHomeStore Error 4818 Infostore for the mailbox /o=Target Org/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=name was not found in the GAL."
Mailbox and public folder databases in Exchange 2007 organizations are created with blank displayName parameters. As a result, the Public Folder Target Agent and Mail Target Agent stop working.
To resolve this issue you must specify the displayName values for the Exchange 2007 mailbox and public folder databases.
You can do it either manually, as described below, or using the SetStoreDisplayName.js script located in the QMMEx Reskit\Scripts folder on the Migration Manager Installation CD. You must run the script after you install Quest Migration Manager.
To set the displayName value for the Exchange 2007 mailbox and public folder databases objects manually, complete the following steps:
1. From the Start menu, select Run... and in the Run dialog type ADSIEdit.msc. Click OK.
ADSIEdit utility is a part of the Windows 2000/2003 Support Tools. To install the Support Tools run the Support\Tools\Suptools.msi file located on the Windows 2000/2003 CD.
2. In the ADSIEdit snap-in, browse to the CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=<ExchangeOrganizationName>,CN=Microsoft Exchange,CN=Services, CN=Configuration,DC=<...>,DC=<...> container.
3. For each Exchange 2007 server involved in the migration, complete the following steps:
a) Open the CN=<StorageGroup>,CN=InformationStore,CN=<ServerName>,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=AdministrativeGroups,CN=<ExchangeOrganizationName>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<...>,DC=<...> container.
b) For each mailbox and public folder database, complete the following steps:
Right-click the database object and select Properties from the shortcut menu.
On the Attribute Editor tab of the object Properties dialog copy the adminDisplayName attribute value to the displayName attribute value and click OK.
Click OK to apply the settings.
