Solution 2

You should run the blocking operation on a separate thread. See this Code Project article: "BackgroundWorker Class Sample for Beginners"[^].

Solution 1

If you are using .net 4+ then try using Tasks

VB

Private Sub tm_Email_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tm_Email.Tick
   Task.Factory.StartNew(
     Sub()  
       If IsConnectionAvailable() = True Then
          sendMail()
       else
          tm_Email.Interval =  600000
       End If
     End Sub
   )
End Sub
