Microsoft Removing Legacy Office 365 eDiscovery Tools

Microsoft announced the retirement of legacy eDiscovery tools from Office 365. The Exchange Online in-place holds and eDiscovery tool, Office 365 Advanced eDiscovery 1, and the Search-Mailbox cmdlet are being retired. All will be gone by mid-2020. It’s a pity to see the Search-Mailbox cmdlet being removed, but time and progress make this kind of thing inevitable.

Office 365 Content Search Actions and Hard Deletes of Mailbox Items

Office 365 content searches now support a hard-delete (permanent deletion) option for the purge action, but only for mailbox items. You can purge up to 10 items at a go. If you have more to purge, you just have to keep on purging until everything is gone. Or use the Search-Mailbox cmdlet, which keeps on proving its usefulness to administrators who need to remove lots of mailbox items quickly.

Using Search-Mailbox to Process Multiple Mailboxes

The Search-Mailbox cmdlet is a very powerful weapon for Exchange administrators. It has some quirks, but the Invoke-Command cmdlet helps us get around one, which is how to use a different search query for each mailbox processed in a set of mailboxes.
