I've seen some vagure references to the RemoteIPRanges property for a Receive Connactor object in Exchange Server 2016 having a maximum number of entries. Does anyone know what this maximum number is at all if in fact there is a maximum? The few references I've seen are either 1200 or 1250.
The schema value for that property will have a fixed length. You can add
as many IP addresses or ranges or CIDR ranges as can fit in the array.
So for example you can get more 22.214.171.124 type ranges (7 characters) than
126.96.36.199/32 (18 characters)
