An accountant needed to setup the latest myob v17 on a customers computer, but found an aspect that didn’t work: the send to… email option (eg for invoices and quotes) didn’t work.
It seems the problem is either with vistas windows mail, or with myob itself.
So I found the easiest solution was to install mozilla thunderbird (to replace windows mail).
The installation and configuration were as easy as most other email clients.
And a test from MYOB found that it could now send emails via thunderbird.
The only problem was that I couldn’t find a way to transfer emails from windows mail to thunderbird (but I managed to transfer the address book by exporting to a CSV file).
