Notes about the MSBCM file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The MSBCM file type is primarily associated with 'Business Contact Manager' by Microsoft Corporation. Business Contact Manager is an Outlook add-on. The backup can be password-protected and the password is stored in the .MSBCM file, encrypted using the same format as ZIP passwords.
