Thanks Seb,I think this may help,though all the servers(A,B,C) are in the same domain and the service account through which the Analysis service is to be run is also from the same domain it may be specifically required to allow this windows domain account to run the PI Analysis service on Server C and I think this can be in the AD.

The naming pattern should be resolved at the end time as well if the attribute value changed. Can you try removing the True For setting for testing purposes? We have a known issue that you may be encountering.

Hi Akash, As a first step I would recommend increasing Send Timeout parameter which is part of Email Deliver Channel Configuration. Depending on your network, you can try with value of e.g. 60 seconds. Let us know if it helps! Regards, Piotr
