I'm using an online CRM that does not support automatic forwarding of emails. To get around this, I set up a forward filter and tried out several email clients.
Thunderbird and Postbox had mixed results, some messages didn't get attached correctly to the right CRM contacts (I believe this was caused to mixed formatting on the email clients end).
Outlook 2010 works great and it's what I can use except for the minor annoyance that it uses "fw" instead of "fwd". The CRM does not support the former so all my forwarded emails get that abbreviation slapped on each subject line instead of tripping out out.
Surely there is a way to set Outlook to use "fwd" instead of "fw" but unfortunately not in the software itself. I understand there may be some VB scripts out there to write, but I'm not a programmer so I would prefer an addin if anyone knows of one. I am willing to pay for it, (a fair price) if it actually would work.
