I am developing an addin for outlook. Is there any way to create a meeting without sending an invitation via outlook to all meeting participants?

I am making an outlook add-in using c# VSTO, and I need to make a change to the settings in the window in the image

I am developing a plugin for outlook using c# VSTO and have come across the following problem:
When a user receives an invitation to a meeting, he/she can click on the “Propose new time” button.
Is there any way to intercept the event of clicking this button and do what I need? And does such an event exist at all? If it is possible, please tell me how to do it

I have the following code that takes an email address of received email once it was selected in Outlook Explorer and tries to find other emails that were received from this address.
(I had historical reason to pass both email address and Outlook.MailItem to this function)

I am trying to find the number of occurrences of specific email address in Outlook Contacts in all accounts, whether they are POP/IMPA or Exchange accounts. I did something similar where I detected number of emails in Inbox where ‘To’ email address matched the input email address.
