well thats dumb. set your outlook and phone settings to leave message on server. or, make the switch to gmail. pop3 is very limited when multiple devices are viewing the same account. who is your isp?
No, it's not so dumb - I have the exact same issue.
Mine is even worse, as I have my own domain name and REFUSE to make Google my default email address.
Before I had my Evo, I was able to use Outlook and my Palm Treo with no problems at all. Now, it's not possible. The only thing that changed in my device.
And, I could go down the list of the reasons Gmail sucks . . . but I'll just start at the facts that threaded conversations are horrible, and I need access to my files even if there's no data connection.
So, I feel your pain, mab1376!
