The database user you have configured for the synchronization must have the appropriate rights to the database. To ensure the database user has the appropriate rights, link the database user to the 'IsahMobileSyncRole' database role:

1. Start SQL Server Management Studio, log on to the server and select the database.
2. Execute the following SQL statements:

USE <databasename>;

GO

EXEC sp_addrolemember N'IsahMobileSyncRole', N'<dbusername>';

GO

<databasename> is the name of the Isah database and <dbusername> is the database user configured in the Web.Config file.
