I have an sbcglobal address and use the Yahoo server which downloads to my windows mail live account on my Dell PC. If I have my iPhone even turned on, my windows live mail on my Dell PC will stop receiving mail with error messages stating maildrop is busy. FYI, I have the same yahoo/sbcglobal settings on both devices. For the last 85 hours, I have been troubleshooting this problem with senior technicians at Connect Tech DSL, & Apple to no avail. No one can figure out why this happens. They have all checked out my settings on both devices, and they are they are correct!!!

If I actually even try to send a message to my yahoo/sbcglobal email address, my windows live mail on my PC will not receive any mail until I reboot my computer several times. I do not understand why I cannot use my iPhone and still use windows live mail on my PC at the same time

Have you ever experienced this problem?
