Use the Remove-AddressList cmdlet to remove existing address lists.

This example removes the address list named AddressList1 and all of its child address lists.

> Remove-AddressList -Identity “AddressList1”

This example removes the address list named AddressList1 (the child address list within AddressList 1 must be removed before this cmdlet is executed)

2) Update Address List

Unfortunately, new address lists aren’t automatically updated in Exchange Online.
