EAC Graph API: Event Updates Trigger Unwanted Invites

Salesforce Einstein Activity Capture (EAC) users experience unexpected meeting invitation emails sent to attendees when modifying non-syncable field values on recurring calendar events synced through Microsoft Graph API. 

Updates to individual occurrences within a recurring event series, including past or future events, may generate re-invitations even when only non-syncable field data is changed. 

This behaviour stems from current Microsoft Graph API limitations that prevent suppression of meeting notifications during event modifications.

This behaviour has been confirmed in the following scenarios:
1. **Past Event Update**: Modifying a non-syncable field on a single past occurrence within an event series results in a re-invitation email sent to all attendees.
2. **Future Event Update**: Modifying a non-syncable field on a single future occurrence within an event series results in a re-invitation email sent to all attendees.
