asked on
Exchange whitelist sender IP Address ranges?
Where would one whitelist a customers IP address range in Exchange 2013 AND Exchange Online?
Example:
Is this done by the following?
Add-IPAllowListEntry -IPAddress X.X.X.0/18
They asked us to update our SPF record to add include:theirserver.... which I'm not truly sure we want to do.
But at least the IP Address range would be acceptable...
Ideas? Thanks in advance
