MicrosoftHi Naveen_Shankar , is there any action on users for event invites sent prior to the update?
Will events be automatically reflecting correctly in respective calendars, prioritizing the time-zone of the sender? (which may require the event to automatically change in the receiver's calendar)
MicrosoftEvent organizers will need to update the event to move it into the new time zone. Updating the event will send an update to all attendees with the new time zone information, so it is correctly displayed on their calendars. Guidance is here:

A PowerShell cmdlet is rolling out that will enable Exchange Online administrators to migrate events for their users. A Message Center post will arrive this week with additional details. Given the tight timeline, our guidance is to update events manually following the guidance above instead of waiting for the cmdlet.
