Delete Meetings using a GUI (Exchange On-prem and EXO)

Delete Meeting items from attendees when Organizers already left the company, in Exchange Online.
You can pass a list of users/room mailboxes, and delete all meetings found from a specific Organizer.

There is also a Graph Powershell script that can be used as well here.

As this uses EWS, you will need a "master account" with Impersonation permissions. You can run:

New-ManagementRoleAssignment –Name:impersonationAssignmentName –Role:ApplicationImpersonation –User:<Account>

This will give Impersonation permissions over all mailboxes in the tenant, so is critical that this account is not shared.
We recommend that y ou use the tool initially for a single user/room mailbox, and check you have the expected experience.
Is not recommended to run against an Organizer Mailbox. There is already a builtin command in Exchange Online service for this: Remove-CalendarEvents

Replace Room locations in meetings for new ones (EXO)

There are times that organizations needs to delete some Room Mailboxes, but if those mailboxes have some meeting items already scheduled, we actually need to replace for a new Room Mailbox.
This is usually a tedious task that every meeting Organizer should do, by removing the previous Room mailbox, add the new one, and send the update to all attendees.
We have made this script in order ease this task for admins.

As this uses EWS, you will need a "master account" with Impersonation permissions on your mailboxes. You can run:

New-ManagementRoleAssignment –Name:impersonationAssignmentName –Role:ApplicationImpersonation –User:<Account>

This will give Impersonation permissions over all mailboxes in the tenant, so is critical that this account is not shared.
