New-ComplianceSearch: how to use the newer version of Search-Mailbox

[Update]: This blog post was last updated on April 22, 2024. Search-Mailbox seems to be gone for good and the new method’s limit is upgraded from 10 to 100 items.

As announced in this Microsoft article, the date for retirement of legacy eDiscovery tools was moved from April 1, 2020 to July 1, 2020. That is when Search-Mailbox cmdlet lost its official support. While the Search-Mailbox did work for some time after this date, now you can use it only on on-premises Exchange. What about Exchange Online and Microsoft 365? Well, there’s a new sheriff in town and its name is New-ComplianceSearch. The cmdlet is a bit more troublesome to use, so I’ll do my best to show you how to come to terms with it.

How to use Office 365 Message Encryption to protect emails sent externally

[Update]: The article was updated on March 26, 2024 to reflect the latest developments in Microsoft 365 message encryption, e.g. licensing requirements.

Email encryption provides additional layer of information security by making sure only intended recipients can read messages. If you are looking for a user-friendly email encryption solution for your Microsoft 365 organization, there is a native tool for that – Office 365 Message Encryption (OME). Now, although the OME name is still in use, the official, up-to-date name is Microsoft Purview Message Encryption. It’s not quite the same, since OME was deprecated on July 1, 2023. But, like with most name changes, OME is and probably will be used for a long, long time to come, so I’ll use it interchangeably. Anyway, from the user’s perspective, OME is the easiest encryption method to use: it can be configured so that it does not require any additional actions on their part. From the recipient’s perspective, this form of email encryption works seamlessly with Microsoft 365 accounts and offers an intuitive experience for all other email clients and email service providers. Read on to learn how to create a Microsoft 365 sensitivity label and use it in a transport rule to encrypt emails and files.
