My OS is windows 7 prof 64 bit and I use Outlook 2007. I have verizon FIOS for my ISP and my email accounts are msn and verizon.net. The msn is configured as a MAPI and the verizon as a Pop3. The msn acct is the default account to send and receive. But of late whenever I send an email using the msn account, the email sits in the verizon.net account's OUTBOX not leaving it. How do I correct this problem. Thank u.
