Before I had Outlook 2007 32bit and QuickBooks 2012 Pro (R12), everything was working fine. I since upgraded to Outlook 2010 64bit but found my Google Calendar Sync was not supported anymore under OL 2010. I uninstalled OL 2010 and reinstalled OL 2007 and now it doesn't show as an option to email Invoices out of QB?????
I attached some screen shots of the error and email setting in QB. In the select email drop down OL isn't listed.
If I right click a file, say from my desktop, and do a "Send To Mail Recipient" it will attach to OL an open a new email no problem! (Seems Windows knows OL is my default email Client).
I have since, uninstalled and then reinstalled OL and QB's. No Change!
