I am getting an error right after saving signatures. We are Win 7 and Office 2013 environment. 
Unable to find type [Microsoft.Office.Interop.Word.WdSaveFormat]: make sure that the assembly containing

The problem was solved as the path was not accessible. 

Hi,

Your script is very good and saved me a lot of work.

But since I needed to be able to set the new signature as default (not forcing), I changed a bit the script, adding this lines so it makes the signature as the default one ;)

As some people may need I put the lines I added here:

$EmailSignature.NewMessageSignature = "SignatureName"  #insert the signature name
$EmailSignature.ReplyMessageSignature = "SignatureName"  #insert the signature name
$MSWord.Quit

You must replace the SignatureName with the name you choosen on the beginning of the script ;)

Hi, Can you please tell me in which line to put this code to set the signature default for Outlook new and reply e-mails? Thanks
