Hi kjh31,
A warm welcome and thank for posting on our community forums. How frustrating for you not to be able to see your sent emails before the 25th of February this year.
As our valued member @用心棒 has given some great advice, have you managed to follow the instructions to see if this resolved the issue?
We're you able to go back further than the 25th of February?
Please let us know so we can assist you further.
Kind regards Jodi.
