Hello all,

I have  data driven subscriptions which are working fine for some subscription and one i have newly developed 

which is used to send the missing punch report to employees

Now , when the subscription runs it shows that all have gone email in report server but some of they are not getting any email 

i have tested it on my id to send each ones report to me but i also get sometimes 2 of 15 , 4 of 15 or else but not all

i also checked mailroot folder under my server's inetpub there are nothing stucks. How to check why is it not sending email to all employees ??
