Identities worked great with the old 4.5 connector and Outlook 2003. I set up 3 Identities such as this:
email@example.com (primary email)
and I could enter any of those email addresses into the From: field in an Outlook email and send messages as if they were from those addresses.
Now i've upgraded to Outlook 2007 (clean fresh install of Outlook) and the 5.0 connector. Now anytime I send an email with a From: address other than the primary email, I get an "Undeliverable" bounce back.
Also, the new Personas panel doesn't seem to do anything for me. If I set it to anything but my primary email address/acct, then I get an "Undeliverable" bounce back. The drop down for choosing the email address also ONLY has my primary email address. Each "persona" effectively has only one email address to choose from.
Note that the web interface works fine as it did in 4.5. Sure would be nice to have 5.0 working, too.
