Although Office 365 supervision policies are intended to monitor a subset of user communications, usually involving specific groups of people, you might want to use a policy to monitor all email. In that case, how do you make sure that your policy has everyone in scope? The problem is that supervision policies don’t support dynamic distribution lists, so you need to do some work to build and maintain a distribution list containing all user mailboxes.
Last week, we taped episode 14 of the Office 365 Exposed podcast in Building 27 of Microsoft’s HQ in Redmond. Topics covered include battling attacks on Exchange, the need to upgrade old Exchange versions, Teams announcements at Enterprise Connect, and how the base Office 365 workloads handle retention storage. We think it’s an interesting episode. Get it from iTunes now!
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.
Exchange Online protocol authentication policies control what protocols a user can connect to mailboxes with, but it would be much better if we didn’t have to worry about some old and insecure protocols. Azure Active Directory gives Office 365 tenants the chance to clamp down on IMAP4 and POP3 connections and close off some of the holes that attackers try to exploit. Microsoft says that this can lead to a 67% reduction in account compromises, so that’s a good thing.
