Answer 1

Using @Lee.J.Baxter 's method (Which was great as the others id not work for me!) I escaped the Extension Method and just added it inline within the form itself:

OleDbConnection con = new OleDbConnection(string.Format(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source='{0}'", DBPath));
OleDbCommand cmd = con.CreateCommand();
con.Open();
cmd.CommandText = string.Format("INSERT INTO Tasks (TaskName, Task, CreatedBy, CreatedByEmail, CreatedDate, EmailTo, EmailCC) VALUES('{0}','{1}','{2}','{3}','{4}','{5}','{6}')", subject, ConvertHtmlToRtf(htmlBody), fromName, fromEmail, sentOn, emailTo, emailCC);
cmd.Connection = con;
cmd.ExecuteScalar();
using (OleDbCommand command = new OleDbCommand("SELECT @@IDENTITY;", con))
{
    ReturnIDCast =(int)command.ExecuteScalar();
}

NOTE: In most cases you should use Parameters instead of the string.Format() method I used here. I just did so this time as it was quicker and my insertion values are not coming from a user's input so it should be safe.
