A question asks how to remove a bunch of emails from a shared mailbox. You can use OWA to do the job, especially with its Cleanup Mailbox option, but perhaps some administrative action is needed.
Microsoft is working on tools to move email, calendar, and contacts from G Suite to Exchange Online with availability in Q2 2019. It’s hardly a surprise.
Microsoft has launched Privileged Access Management (PAM) for Office 365. The name’s incorrect because PAM only works for Exchange Online right now. PAM is based on RBAC, which is good, but is the implementation too Exchange-centric?
Exchange administrators are accustomed to looking through mailbox audit logs to find details of events. Those same events are in the Office 365 audit log, so that’s the place to go look for information, like when you want to find out who sent a message from a shared mailbox using the SendAs permission.
Office 365 offers different ways to apply encryption to important messages. When those messages hold sensitive data known to Office 365, like credit cards or passport numbers, we can define a transport rule or DLP policy to protect outbound email automatically. And while you can define rules and policies through the GUI, PowerShell is available too.
If you run a hybrid Exchange deployment, you probably have some on-premises distribution lists that you’d like to move to the cloud. Office 365 offers no way to do this, so it’s up to PowerShell. Instead of starting from scratch, you can use a script created by Tim McMichael of Microsoft and amend it to meet your needs. PowerShell is just great.
Microsoft has released a preview of the cmdlet set to allow tenants to create and manage protocol authentication policies for Exchange Online. It’s a great chance to disable basic authentication and reduce the attack surface for password spraying.
A recent update for Exchange Online gives extra control over who can access public folders. The change is intended to help with scalability, but it can be used to turn public folders off for any mailbox for which you care to disable access.
Microsoft issued Message Center update MC151582 to tell Exchange Online administrators about a new default value for automatic processing of events sent to room mailboxes. Unfortunately, the PowerShell code in the update contains an error, so here’s some fixed code to check existing values and to set them to the new default, if you want to do that.
