Pocket Outlook won't send attachment

[finisterre]

Hi,

I'm trying to forward an email that has a 15KB pdf file attached.

I've tried 2 known good SMTP servers. Both give "The message(s) could not be sent. Check that you have network coverage and that your account information is correct. Then try sending again."

Despite the message, the email is sent (and arrives) but without the attachment. I can read the PDF fine on the phone.

All other messages send OK.

Any ideas?

Thanks.
