Edit Registry key

Sometimes due to wrong setup of registry key, Outlook does not allow you to synchronize Offline Address Book. You need to modify the registry key. Have a look at the steps below:

• You need to start an export tool, i.e. MFCMapi.exe.
• Click on Session, and then click on Logon and Display Store Table.
• Pick up the profile for User B and the permit credentials for User A.

NOTE: You’ll need to edit the profile to prompt for credentials if in case you’re not logged on as User A.

• Click on Public Folders.
• In the lower panel, right click on the Property.
• PR_ADDRBOOK_FOR_LOCAL_SITE_ENTRYID, then after click on Open as Entry ID or Object.
• Click on OK.
• The Address book will be in the form of
• EX:/o=<var>OrgName</var>/ou=<var>SiteName</var> rather than /o=<var>OrgName</var>.cn=addrlists/cn=oabs/cn=Default Address List.

To resolve this issue, set the registry key as following:

• Click on Start >> click on Run >> in the Run command box, type regedit and then click on OK.
• In the Registry Editor, navigate to the following registry sub-key and click on it:
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\<var>ServerName</var>\Public-<var>GUID</var>.
• Under the Edit menu, click on New >> click on String Value and then type the value: Default OAB DN.
• Right-click on Default OAB DN and then click on Modify.
• In the Edit String dialogue box, type the attribute LDAP Distinguished Name (DN) of the OAB. For example, the default attribute Offline Address Book DN may resemble the following attribute:

• Click on OK.
• Exit the Registry Editor.
• The users have to log-in again for this to work.
