Hi larose532,
Welcome to Microsoft Q&A forum.
Please kindly understand that currently in Microsoft Q&A we only support English. And I am trying to use machine translation to read your question. If I have any misunderstandings, please accept my apology and re-describe in English so that we can better help solve your issue.
If you want to automatically forward meeting invitations when they arrived your mailbox, it is suggested for you to create an Outlook rule like below to achieve that. (Home > Move > Rules > Manage Rules & Alerts)
If you want to automatically forward meeting invitations after you clicked the "Accept" option, I'm afraid it is impossible only with Outlook options alone. I did some search and tests, and found this VBA method mentioned in this article: How to Auto Forward a Meeting Invitation to a Specific Person when Accepting It in Outlook could help achieve what we want. (Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.)
Hope this can be helpful.
