This is a unique observation that I have, perhaps will be helpful to many OL users:
I normally reply to a large number of messages (from various people) in a given folder/s. I do this by creating an OL Template and then putting this Template in a rule and then executing the rule. This sends out a large number of standard messages in no time.
What I have observed is that OL will automatically not send out duplicates of the messages and will not send the mail twice to the same email id for a few days.
Two queries on this:
a: Where does OL store the sent email ids for each template ?
b: Can we change the number of days for which the duplicates will not go out ?
