Microsoft Power Automate template
Update Google Calendar events previously created from Office 365
By Microsoft Power Automate Community
If you previously used the Office 365 to Google Calendar template to copy new events from Office 365 to Google Calendar, then you can use this template to update those events. Note, this will only update events between now and the next 45 days that have specifically been copied by the flow template that puts the Event ID into the description of the events.
