Excel VBA calendar planner

I have a macro that is not behaving as expected, it runs and does what i have asked it to do however i have encountered an unexpected issue.
what i wanted to do was have the invites sent from a shared mailbox which it does, however the meetings now appear in my main calendar as well - it is over 300 appointments so it has made my own calendar a bit of a mess

Code attached



can anyone tell me what i have done wrong with this one?
