Exchange 2007/2010: Feil ved oppsett av brick - level

MS Exchange 2007 / 2010 Server
Cannot create MS Exchange mail level backup set (e.g. MAPI error while creating backup set):

  1. Check if the system account running OBM has been granted full mailbox access. If not, please do so by following the instructions as follows:

    • Click Start, point to Microsoft Exchange Server 2007 or 2010, and then click Exchange Management Shell

    • Enter the following command:

      Get-Mailbox | Add-MailboxPermission -AccessRights FullAccess -user %windows_account%

      Where %windows_account% is the actual username of the system account that runs OBM. (e.g. administrator):

    • Restart the "MS Exchange Information Store" service afterward

  2. Check if the system account used to create the mail level backup set is an Exchange Organization Administrator and a Domain Administrator:

    • Click Start, point to Control Panel, Administrative Tools, and then click Active Directory Users and Computers

    • Browse to the OU containing the corresponding user

    • Right click on the user, and select Properties
    • Select the Member Of tab to check on the membership setting

      Figure 10.0 - Active Directory Users and Computers

  3. Check if the system account is mailbox-enabled, and its email address is not hidden from the Global Address List:

    • Click Start, point to Microsoft Exchange Server 2007 or 2010, and then click Exchange Management Console

    • Expand Recipient Configuration, and then Mailbox

    • Right click on the user, and select Properties
    • Select the General tab to check on the setting

      Figure 11.0 - Exchange Management Console

    A mailbox-enabled user is a Windows Active Directory user that has one or more Exchange Server mailboxes associated with it (http://support.microsoft.com/kb/275636/en-us).

  4. Ensure that the "MS Exchange Information Store" service is restarted after a permission change:

    Figure 12.0 - Windows Services

    After a permission change, you may have to log off and log back on. Microsoft also recommends that you stop and restart all Exchange services. If you have multiple domain controllers in the forest, you may also have to wait for directory replication to complete.

  5. Check if the Public Folder Database is available and mounted in the Exchange Management Console:

    • Click Start, point to Microsoft Exchange Server 2007 or 2010, and then click Exchange Management Console

      Figure 12.0 - Exchange Management Console

      If the Public Folder Database does not exist, please create an empty Public Folder Database.

      Instead of modifying the MAPI profile properties suggested in the following article, we recommend creating an empty Public Folder Store. It will then allow OBM to connect to the MS Exchange 2007 server via MAPI:


  6. Check on the version of 'Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1' in use

    • Check on the installation date of the MapiCdo

      Figure 13.0 - Programs and Features

    • Check on the version of all dll files found in - C:\Program Files (x86)\ExchangeMapi

      Figure 14.0 - Windows Explorer

      The version of all dll files must be the same.

      If an older version is in use, please re-installing the newest version of MapiCdo (e.g. Windows 2008 Server is only supported in the later release of the MapiCdo). MapiCdo can be downloaded at:


  7. Check if all MS Exchange related services have been started. Pay close attention to the "MS Exchange Information Store" and "MS Exchange System Attendant" services

    Figure 15.0 - Windows Services

  8. Check if the MAPI profile is correctly configured:

    • Download the MFCMAPI 32-bit executable (MfcMapi.exe)

    • Open the MAPI editor

    • Select Profile, and then Show Profiles:

      Figure 16.0 - MAPI Editor

    • Right click on the Online Backup Manager profile

    • Select Open Profile:

      Figure 17.0 - MAPI Editor

    • Right click on the Microsoft Exchange Server entry and then select Configure Service:

      Figure 18.0 - MAPI Editor

    • Enter the local IP address of the MS Exchange server in the Microsoft Exchange server text box, and username in the Mailbox text box, press Check Name for validation, and Apply afterward:

      Figure 19.0 - MAPI Editor

      If the local IP address cannot be resolved, please enter the corresponding IP address and hostname within the hosts file found in the directory - C:\WINDOWS\system32\drivers\etc\

      Example:                Exchange2K3

    • Restart the OBM client software afterward

  9. Check if there is an Outlook or BlackBerry MAPI profile existing on the affected server (e.g. using the MAPI editor as shown above)

    In some cases, the Outlook or BlackBerry MAPI profile may have an effect on the backup operation if they are generated before the OBM MAPI profile.

    For these cases, remove the Outlook or BlackBerry MAPI profiles temporarily, and re-create the OBM MAPI profile by logging to the OBM backup client application, and re-creating a new mail level backup set.

  10. Verify if there is any Java crash error by running OBM in debug mode:

    • For cases where OBM crashes on dll file that relates to Windows, further research must be performed on the corresponding dll file

    • For cases where OBM crashes while opening a particular mailbox persistently, further research must be performed on the mail items  stored under the particluar mailbox.

    For detailed instructions on how to run OBM in debug mode, please refer to Article #2687

  11. Perform a version comparison on the dll files on the client against our own machine. If possible, we may give our file to the client for testing purposes

Common Issues
The following are some common issues of MS Exchange mail level backup:

  • Invalid XML -
    Ensure that the OBS server application is in the latest stable version. For OBS in older version, please upgrade to the latest release. Instruction can be found in the Ahsay Backup Software Upgrade Guide 

    For persistent problem on the latest version of OBS, kindly refer to the following instructions for further troubleshooting:

    1. Generate the backup set file list to an output file:

      • Open the batch file "ListBackupSetFile.bat" located in ${Install-Home}\bin using a text editor
      • Modify the value of "BACKUP_SET" to the name of the problematic backup set
      • Execute the batch file 
      • When the process is completed, a "dump.xml" file would be created in the ${Install-Home}\bin directory

    2. In the client logs, identify where the "LastXMLDir=" error was flagged, for example:

      MAIL-SRV\Mailbox Store\%2fO%3dWMI%2fOU%3dFIRST+ADMINISTRATIVE+GROUP%2fCN%3dRECIPIENTS%2fCN%3dKARENL\Inbox\000-All mail thru 03-03-2008

    3. In the client logs, identify where the "LastXMLFile=" error was flagged, for example:


    4. Open the dump.xml file generated from Step 1, search for the long sting .msg file name found from Step 3. Using the example above:


    5. Identify the email subject of the problematic email by identifying the 'MSUB=' attribute that follows '.msg', for example:

      MSUB="RE: Email/Subject using TaM"

    6. In some cases, there may be multiple entries of the same .msg file within the dump.xml, identify all related "MSUB=" attributes for these caes

    7. Identify the problematic email on the OBS management console:

      • Select [Manager user] > [Username of the affected user] > [File Explorer]
      • Select the problematic mail level backup, and the 'Show all files' option
      • Browse to the directory found from Step 2
      • Search for all the email subjects found from Step 5

    8. With the email identify from Step 7, the next email listed in the file explorer will usually contain an invalid characters

    9. Remove all problematic email(s) with invalid characters on the OBS management console

  • The system cannot find the file specified -
    For the system cannot find the file specified issue:

    Backup_ID\1189950279609.msg (The system cannot find the file specified)"

    1. Check if there is any anti-virus application installed on the affected server

      If there is, please disable the anti-virus application to resolve the issue. 

      In some cases where an email message may contain virus, as the email is spooled to the temporary location for backup. The anti-virus application will deleted the virus email before its upload, causing the error of file not found to be prompted.

    2. This is also a known issue with OBM version Pre-, when performing a MS Exchange mail level backup for mails residing at the ROOT directory of the Exchange tree.

      In other words, backing up a mail that is not located in any of the user folders, the error would be flagged. To resolve the issue, please upgrade the OBM software to the latest patch release. The instruction can be found in the Ahsay Backup Software Upgrade Guide.
