Hello
We have Exchange Server 2013 in our environment.I had created a mail enabled secuirty group.Inside this groups are few other mail enabled security groups. Basically a group was created with nested groups. There are altogether around 60 users within this group from different databases.
When an email was sent to this group, only 13 users received the email. For others mail delivery failed without any NDR to sender.The email was delivered to 13 random users within the group from different databases.
Kindly suggest me if anyone has faced similar issue and how should I resolve this.
ThankYou
