Resolve DNS, export to Excel and HTML, then send mail - html

Question

I was almost done with my script and did some late night editing and written over my old version so I cannot go back.
The script was running fine, still needed some tweaks but now it ha come to a complete halt.
The idea is to GC a list of IP's. Resolve the IP's and place them in an excel sheet. Then save the sheet to htm and xlsx. And finally mailing those to me.
Now it gets stuck on sorting the sheet, saving AND mailing...
Can someone give me some insight on what I did wrong here?
it gets stuck on sorting the sheet, saving AND mailing.
It no longer sorts B3:B$Count:
Exception calling "Sort" with "1" argument(s): "The sort reference is not valid. Make sure that it's within the data you want to sort, and the first Sort By box isn't the same or blank."
At C:\Folder\Scripts\Get-IP.ps1:137 char:5
+ [void] $objRange.Sort($objRange2)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation
It no longer saves the xlsx file, but does save the HTM file. It is clearly not overwriting something. I even restarted to make sure.
Exception calling "SaveAs" with "1" argument(s): "Microsoft Excel cannot access the file 'C://Folder/BlockedIP/HTML/2014-07-08/0BCEF810'. workbook."

+ $b.SaveAs("$FileXML")
+ ~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : ComMethodTargetInvocation
And finally, it will no longer send me e-mails:
New-Object : Exception calling ".ctor" with "2" argument(s): "The specified string is not in the form required for an e-mail address."

Exception calling "Sort" with "1" argument(s): "The sort reference is not valid. Make sure that it's within the data you want to sort, and the first Sort By box isn't the same or blank."
Double-check that $objRange and $objRange2 reference the correct ranges:
$objRange.Address()
$objRange2.Address()
Not much else I can tell you here without seeing your actual data.
Exception calling "SaveAs" with "1" argument(s): "Microsoft Excel cannot access the file 'C://Folder/BlockedIP/HTML/2014-07-08/0BCEF810'. workbook."
If the path really were C://Folder/... you'd be getting a different exception. Please do not fabricate error messages.
New-Object : Exception calling ".ctor" with "2" argument(s): "The specified string is not in the form required for an e-mail address."
You're confusing MailMessage and SmtpClient class. Not to mention that you don't even need either of them, since you're using Send-MailMessage anyway. Just remove the following 5 lines:
$SMTP = New-Object System.Net.Mail.MailMessage($SMTP, 587)
$SMTP.EnableSsl = $true
$SMTP.Credentials = New-Object System.Net.NetworkCredential("$username", "$password");
$SMTP.isbodyhtml= $true
$SMTP.Send($From, $To, $Subject, $FileXML, $Body)

Answer 2

Solved the sorting problem by altering the code to:
$objRange = $c.Range("A$($iRow):E$($intRow)")
$objRange2 = $c.Range("B$($iRow):B$($intRow)")
[void] $objRange.Sort($objRange2)
Turns out it got stuck on the header in the xml file
Replaced mailing with:
$From = "Blocked IP <#####.##>"
$To = "IT Dept <#####.##>"
$CC = "Someone <#####.##"
$Subject = "Blocked IPs for $date ($Count Total)"
#The href should point to the htm file in your iis/apache folder.
$WebLink = $FinalIPAddress+$FileHtmlWeb
$here = "<a href='http://$Weblink'><b>Here</b></a>"
#Define the body of your e-mail, in this case it displays a message and shows the server it is send from with it's local IP.
#A link to the .htm file, how many IP's were blocked and the date of the message.
$body = "Dear <font color=black>$to</font>,<br><br>"
$SMTPServer = "smtp.gmail.com"
$SMTPPort = "587"
$Username = "###gmail.com"
$Password = "##"
$message = New-Object System.Net.Mail.MailMessage
$message.IsBodyHTML = $true
$message.ReplyTo = $From
$message.Sender = $From
$message.subject = $subject
$message.body = $body
$message.to.add($to)
$message.from = $username
$message.attachments.add($MailXML)
$smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort);
$smtp.EnableSSL = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password);
$smtp.send($message)
The saving of the file turned out to be a misguided path.
Since the excel sheet was created from folder1 it wouldnt save instandly to folder 2 since its temp save file would remain in folder1.
