Error while sending outbound email

Hi All,

I am using Office365 for sending and receiving emails. I am using same smtp-client for sending all outbound emails. For some mailboxes it is working fine but for some mailboxes it is not working and throwing below error.

Need to check logs for the root-cause. In case, you enabled debug, you should see communication details between ESJ and EWS server.
