Emailing Invoices as PDF

We are currently using PCLaw Pro v9.31b and Outlook 2003.  We create all of our invoices in PCLaw and then email the PDF version to our clients.  We have been doing this successfully since October 2008.  Recently we have been told by 2 clients that the PDF attachment was not included in the email.  Our sent items show the attachment was sent.  We have worked with one client extensively on this.  They can receive all other PDF attachments but any PDF created by PCLaw is stripped out.  We have tried renaming the PDF and sending to no avail.  If PCLaw created it, they cannot receive it.

Another client is receiving the email but now the attachment is converted to a winmail.dat file.  Has something changed in a PCLaw update since October that would have caused this?  Anyone have a fix we can implement short of having all of our clients change their email accounts just to receive our invoices?  Any help would be appreciated.

Amy,

This could quite possibly be a bug not yet reported to tech support or discovered by anyone, other than yourself.  9.31b is a very recent release.  Have you called tech support to report it?

When you say "any PDF created by PCLaw" do you mean that you also tried to create a PDF report and that failed too?  Or did you just try to do bills?

Amy,

One other thought....What version of Internet Explorer are you using?

Lexis recently sent out a technical bulletin advising that IE8 was incompatible with PCLaw.  They only reported issues with font sizes, etc.but if you are using IE8, then it may be related.

Amy,

Some email services strip attachments if considered SPAM or even if a virus is detected.   
I suggest:

1. Verify that the sending computer isn't infected. 
2. Have the recipient check their spam folder/logs to see if that's the case.
3. Check YOUR spam filter to see if it's stripping it after you send it.

As for the winmail.dat file.  God, I hate those and really can't be much help.
