About 4 years ago I linked my BigPond account with my Hotmail account, ie. I set up forwarding of my BigPond emails into my Hotmail account.

This has worked very successfully until approx. 4 weeks ago when some of my BigPond emails stopped showing on my Hotmail account.

I have been in touch with BigPond and they say the problem isn't theirs.

I am not particularly computer savvy and don't have a clue as to what to do.  I have tried resetting the forward function to no avail. 

Any help would be greatly appreciated.
