Problem submitting pdf file to next signatory via email

[martin385595927o8q]

I have a pdf form from the bank- mandate to add account holder. I can insert various bits of data fields into the document- name/address/date etc. When all that is done, ther eis the option to submit the document.  I can either send it to my bank, OR I can send it to the next signatory. 
The Problem :- it opens my Mozilla Thunderbird news readr instead of MS office outlook. Outlook is set in my default apps as the default mail app. If tried all I can sensibly try from web suggetions- removing the pdf option in Thunderbird but I cannot get the form to open outlook to send via email to the next person. 
Can anyone make any suggestion ? I'm stumped 😞 ( I'm also not very PC savvy - I'm using a windows 10 PC)

Are you trying to submit from the web browser?  Try saving the PDF locally then sending to the next person by email.

Yes, that does work! It's a step forward at least. I just don't know how I'm going to send it to the bank using 'submit' in the pdf form. That's a problem for tomorrow... thanks so far.! I enteredsome random data into the file, saved it, and sent it to myself. 
I then opened it and it had all the random data....

If the file has a Submit button in it, it will probably (hopefully) send the data in it to the bank as soon as you click it. Otherwise, there should be instructions on how to submit it back to them.

I can't try that until I get everything together... the first party is in South Africa and sh's struggling with the form. Hopefully she'll get that sorted tomorrow now that I have figured how to do it...Many thanks.!

The core error was in Mozilla Thunderbird. I had to set up a gmail account and disable their default pdf reader and tick ' check every time on starting the app'.
