Hi... I am seeing this below error for subnet on all my mailbox server. I was told by my exchange admin team that this subnet was removed and it has a new subnet now , but i am still seeing the old subnet on Solarwinds "Appinsight for Exchange". Can anyone help me for to resolve this. Also Is there anything on the mailbox server that i can run to check if the old subnet still exists. I have 4 Mailbox servers.
