Am taking a punt that this might be an appropriate forum!

Why is it that until last week I could receive my Outlook emails simultaneously on my iMac, my MacBook Pro and my HTC Wildfire phone. Now I only get them to my iMac apart from occasional receipts on my other 2 devices. My Netgear Router settings have not been changed and my email account settings have not apparently been altered either. I can send emails no problem at all - except on my phone - but that's another matter!!

Grateful for any steers from anyone please.
