• You have a computer that has Outlook 2003 (SP2) or 2007, Exchange 2007 Management Tools (32-bit version), PowerShell and .NET Framework installed
• Logon with an account that has Exchange Server Administrator and Local Administrator rights
• You have full access to the users’ mailbox on both servers. See the note below on how to do it.

1. Start the Exchange Management Shell and type the following:[PS] C:\>Get-Mailbox –Database “<Exchange Server FQDN>\<Database Name>” | Export-Mailbox –PSTFolderPath C:\PSTFiles to export all users mailbox to a PST file. Press A for Yes to All. Depending on the size of your database, the export procedure could take a long time to complete.
2. Now the mailboxes are exported to the PST files, make sure that the PST file name matches the alias of the users’ account in the other domain.
3. Next, import the PST files to the other Exchange Server by typing the following: [PS] C:\>Get-Mailbox –Database “<Exchange Server FQDN>\<Database Name>” | Import-Mailbox –PSTFolderPath C:\PSTFiles and press A for Yes for All. Wait until the import operation completes.

Note:
To grant the Administrator Full Access rights on the database type the following command:
[PS] C:\>Get-Mailbox -Database “<Exchange Server FQDN>\<Database Name>” | Add-ADPermission -User Administrator -AccessRights GenericAll

Ok, long story short, it all started with a Backup Exec 12.0 job suddenly failing.. One part of the whole job is backuping Exchange Server 2007 using a remote agent and the exchange server. In the job log of Backup Exec, i got a ‘Final error: 0xe000fed1 – A failure occurred querying the Writer status. ‘ ok, initially i thought, this is nothing new.. querying the writer status and seeing what this one’s reporting ..

This is the Backup Exec 12.0 Job log:

i got this solved by following MSFT-David Shen’s tip.. => Just deleted a Profile with a .bak extension..

Hi,

According to the research, the issue may be caused by an invalid entry inside the following registry sub tree.

HKey_Local_Machine\Software\Microsoft\Windows NT\CurrentVersion\ProfileList

Please open the registry editor with regedit.

Expand and local to the subtree, check if there is an entry that has a ".bak" value appended. If so, this may be cause the failure when trying to resolve the SID of the writer.

Please backup the registry key first, and then delete that entry with the extra ".bak"

Then you may reboot the problematic server to check if it the issue can be fixed.

Ok, this solved the above mentioned error with EventID 8193

But there was another error, kept me from running the backup job successfully..

Resolve

Modify the access control list on the registration folder

Component Object Model (COM) applications must be able to access the COM+ catalog files that are stored in the COM catalog folder. If the default access control list is changed on the COM catalog folder within the Windows folder, the Shadow Copy System Writer may not work properly.

To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.

To modify the access control list on the COM catalog folder:

1. Click Start, and then click Computer.
2. Navigate to %systemdrive%\Windows.

   By default, %systemdrive% is located at C:\.

3. Right-click Registration, click Properties, and then click the Security tab.
4. Click Advanced, and then click Edit.
5. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
6. Click Edit to view the special permissions assigned to this folder.
7. Ensure that the access control list matches the following criteria:
   • The local Administrators group has Full Control permissions applied to This folder and files.
   • The Everyone group has List folder/read data, Read attributes, Read extended attributes, and Read permissions applied to This folder and files.
   • The local SYSTEM account has Full Control permissions applied to This folder and files.
8. If the permissions on this folder do not match what is listed in this procedure, make the appropriate changes, and then click OK.

Verify

To perform this procedure, you must be a member of the local Administrators group, or you must have been delegated the appropriate authority.

To verify that the Shadow Copy System Writer is working properly:

1. Click Start, point to All Programs, and then click Accessories.
2. Right-click Command Prompt, and then click Run as administrator.
3. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
4. In the command prompt window, type vssadmin list writers.
5. Ensure that Writer Name: ‘System Writer’ is displayed in the list.

I started Process Monitor and found an ACCESS DENIED on C:\Windows\winsxs\FileMaps\$$.cdf-ms for the NT AUTHORITY\NETWORK SERVICE. Funny, the guys writing Technet Articles and Help for MS don’t even know their own system in deep .. rofl .. however, granting NT AUTHORITY\NETWORK SERVICE the necessary rights, solved also this issue.

here’s my powershell get-history (including typos and retries ), maybe it will help you:
