Hi Vignesh,

 

What changes do you need to do ? And what services are needed.

 

Depending your firewall and services used, my approach is that you can start adding the new ip addresses before the effective date to avoid issues. After the change date monitor that the old addresses are not being used and then remove them from your firewall rule and groups.

        Hi ,

          Does Microsoft release these IP addresses for all the O365 services? Meaning , I would like to know whether MS releases these type of IP addresses for Microsoft flow too as Flow is built on top Azure Logic app service and these IP addresses have to point to those Azure data centers where Azure Logic app is built and running .
