- Scenario
- Customizing the online booking page display name for a specific mailbox using backend MAPI tools.
- Observed behavior
- The Bookings with Me page displays a default mailbox name that needs to be updated by editing the Online Booking business information.

Use MFCMAPI to Edit Online Booking Business Information
Modify the mailbox's backend MAPI properties using the MFCMAPI tool to securely update your Bookings display name.
This method involves accessing raw mailbox data. Ensure you modify only the specific text strings mentioned to avoid disrupting other mailbox functions.
Download, install, and open the MFCMAPI application. Navigate to the options menu and enable both the 'MDB_ONLINE' and 'MAPI_NO_CACHE' settings.
Click 'Session' and select 'Logon'. Choose the Outlook profile that is connected to the mailbox whose Bookings name you want to change.
Double-click the mailbox to open it, then right-click the root container and select 'Open associated contents table'.
Scroll through the contents table to find the item named 'IPM.Configuration.OnlineBooking.BusinessInfo'.
Double-click the item, find and open 'PR_ROAMING_BINARYSTREAM'. Carefully change only the mailbox name located between the quotation marks.
Save your changes and close MFCMAPI. Wait several minutes for the servers to sync, then refresh your Bookings with Me page to verify the new display name.
