Hi - it was brought to my attention that our AD environment has many ProxyAddress's<br />
We have already migrated to Exch online - no problems with any mail flow<br />
What is the problem with having all of these old ProxyAddress's on an object? - such as x400 and x500 from days of old exchange servers over decades ? my question is does it really matter ? apart from not looking clean? &nbsp;i realise that if they were removed after recent exchange server upgrades years ago it may have caused NDR,s Ive been here over 10 years and no'one has ever cleaned them up - but the question is there a real technical reason for you having to.? Thanks
