0x800CCC0F with Outlook and PDF attachments


A client of mine suddenly can't send emails with PDF attachments from his HP Windows XP 32bit PC

I tried various tests and Word or Excel attachments transmit fine

I zipped the PDF attachment, but still no go

I disabled ESET Nod32, but no improvement

Any ideas ?

Is there an Antivirus software on the computer?  Can you disable it and try again?  If that fixes it then you will need to make an exception for Outlook.

If possible you can also try deleting and recreating the email account in Outlook.

Thanks for the response

Like I initially indicated, I had tried disabling the antivirus

I the client can send and receive emails

It's just the emails with PDF file attachments that are no longer getting out
Hi Yann,

After researching the error code on Google in regards to this issue it seems as that it's a non-specific error code.  It may even only affect attachments over 2MB and some say it's not attachment type specific.  Try sending a PDF file that's less than 2 MB.

The point is that at this time looking for a specific answer to solve/allow PDF attachment to go through is like trying to find a needle in a haystack.  You can try resetting Outlook to factory default after backing up the emails and reconfigure.  Or you can try uninstalling/reinstalling Outlook.
