Hello,
thank u so much for your explanation, please let
-I have full access at ISP DNS records creation and modification
-no zones created at ISP nor GTM itsself
-what I did :
1-delete A records from ISP side
2-create NS record at ISP side
2-create same A records at GTM
no I plan to migrate MX and TXT resource records from ISP to GTM but when I use same steps to create VS>POOL>WideIP I cant configure the data itself at MX records
then I found a document to create it using zone runner but by using DNS ›› Zones : ZoneRunner : Resource Record List then create and choose type MX
but unfortunately I couldn't complete the steps as MX should return data like xxxxxx.mail.protection.outlook.com.
