bvtech,
The Configuration Wizard is only to be used once during the initialization of the system!! This is why certified technicians should be setting up more complicated features of a system.
Yes, the system works with G-Mail, Office 365, and Exchange with no problem.
First of all GMail has changed how things work on their system and you have to make sure the e-mailbox is setup correctly or it will refuse to talk to the MiVO-250; have you done that?
My suggestion would be to get a certified technician to come out to help finish this up before you corrupt your system by constantly resetting it.
Thanks,
TE
