Restoring/recovering an edited message
Can the original message which has been posted in Teams (Chat or Channel), which has subsequent been edited, be restored/accessed. Scenario: A student posts an inappropriate message in a chat or...
The only way would be to perform an eDiscovery search and recover the message from the copy stored within the Team/personal mailbox.
Just to add some information, edited Teams 1:1 messages can only be restored if the mailbox of the user (where the messages are stored) is on Litigation Hold.
