You receive this message when you attempt to connect to a database located on another computer, and the connection is not completed. The most likely reasons for the connection not completing are:
Your user name has not been granted access on the computer on which the database is located.
To give you access, the database owner must create a user account for you on that computer. The database owner must also grant you access to the database by selecting your name on the Select Users page of the Manage Sharing wizard. Contact the database owner to ask or confirm that you have been granted access.
The password that you are using to log on to the remote computer (the computer on which the database is located) does not match the password you use to log on to your local computer (the computer you are currently using).
To gain access, you must change your remote password (the password that you use to log on to the computer on which the database is located) to match your local password (the password that you use to log on to the computer you are currently using). Click the Change Password button.
Each computer must be running the same version of Business Contact Manager for Outlook for each user to connect to a shared Business Contact Manager database.
Tip: The database owner must select the with users working on other computers in my network check box in the Manage Sharing wizard to grant access to someone who will connect to the shared database from a different computer. To add a new user whose name is not listed, on the Select Users page, click Add New User. If you are part of a workgroup, the database owner must specify a temporary password for each user. The password cannot be blank.
