There was an error parsing the query. [Token line number,Token line offset,,Token in error,,]

I am getting an error at the ExecuteNonQuery and really don't know why. I spent a lot of time searching the web and realized that User has to be between [], but it hasn't solved my problem.

else {
    DataTable table = new DataTable();
    string query = "SELECT * FROM [User] WHERE Email = '" + tbMail.Text + "'";
    OleDbDataAdapter adapter = new OleDbDataAdapter(query, connectionString);
    int count = adapter.Fill(table);
    if (count != 0)    {
        MessageBox.Show("This email is already in use", "Email in use", MessageBoxButtons.OK, MessageBoxIcon.Information);
    } else {
        OleDbConnection connection = new OleDbConnection(connectionString);
        OleDbCommand insertCommand = new OleDbCommand();
        adapter = new OleDbDataAdapter();

        string encryptedPassword = Convert.ToBase64String(System.Security.Cryptography.MD5.Create().ComputeHash(Encoding.UTF8.GetBytes(tbPass.Text)));

        connection.Open();

        string command = "INSERT INTO [User] (Username, Password, Email) VALUES('" + tbUser.Text + "', '" + encryptedPassword + "', " + tbMail.Text + ")";
        insertCommand.Connection = connection;
        insertCommand.CommandText = command;
        adapter.InsertCommand = insertCommand;
        adapter.InsertCommand.ExecuteNonQuery();

        connection.Close();
    }
}

The error is:

Your email value must be between quotes, just like username and password.

Another point is that you should use sql parameters to prevent sql injection attacks.
