Inbound EMail VS Interactions created

Hi,

We are using CRM 7 and ERMS is setup and running without any issues. When an inbound email received to specific mail id, ERMS will create interaction record(Activity) in CRM.

Sometimes we are finding issues like customer send an email, received to outlook, received in CRM from outlook but Interaction record not created. We are checking number of interactions created in CRM with user WF-BATCH as it create through workflow.

Is there anyway otherway to see number of inbound emails received vs number of Interactions(Activity) created are created. Any standard Table or report available for this?

Shaik.
