Q: My MobileMe e-maIl suddenly won't work, says I'm offline, but I'm NOT!

Hi nancy,

Thank you for using Apple Support Communities. 

If you are getting a message from mail that your account is offline, the following article provides a place to start to resolve that error. See specifically the section "If Mail says that your account appears to be offline". 

If you can’t send or receive email on your Mac - Apple Support

Regards,
