Win XP(SP3)

Recently I decided to try WLM. 

However when WLM had finished importing all my accounts and folders, I found that all 8 of my other email accounts had been separated into individual sections within the folder list.

The beauty of OE is that mail from ALL my email accounts are delivered to one SINGLE inbox .  In WLM I now have to visit each inbox for each separate email account to see if any mail has arrived. 

I have unsuccessfully tried to set a rule to copy emails arriving at my other accounts to my default email account. 

The only workaround  I have at the moment is a rule which forwards emails arriving in my WLM email accounts to my Hotmail account which then forwards those emails back to my WLM default email account.

Is there any other way around this tedious issue?
