Shared mailbox - junk email - who made these changes
Is it possible to check who added emailadress to the junk emaillist on a shared mailbox?
We have a shared mailbox which has been used by a number of users. We need to prove which of those users with access to that shared mailbox has added emailadresses tot the junk emaillist.
Can the logs prove who did these actions? Can we check which IP-adress made the changes? Can we check which user or IP-adress was active on the webaccount on a certain date? Or any other option that will show who made these changes.
Effect was that important emails of a collegues did not arrive in the inbox and were not followed up on.
What's your Exchange server verison? Or are you using O365?
I'm afraid we cannot find who made changes to the Block or allow (junk email settings).
Generally we use mailbox addit log to check what action made by which user to the specific mailbox. And the Mailbox actions logged by mailbox audit logging introduced as below
Or in O365:
Manage mailbox auditing
Search the audit log to investigate common support issues
