Migrating On-Premises Distribution Lists to Exchange Online

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.

Disabling Basic Authentication for Exchange Online (Preview)

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.

Enhancing Public Folder Scalability

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.

AutoUpdate versus AutoAccept

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.

Licensing Exchange 2019 Hybrid

Microsoft has confirmed that they will not release a free hybrid license for Exchange 2019. That’s OK, because if you want to use Exchange 2019 as the HCW host, you simply assign the server one of your licenses. After all, the server won’t simply be running hybrid connectivity, will it?

LinkedIn Connects to Office 365

You can now connect Office 365 accounts to LinkedIn accounts (or block the connection at a tenant level). It’s a nice way to keep tabs on your LinkedIn contacts and find out what they’re doing with a simple click in an Office 365 people card.

Using Special Characters in Office 365 Labels

A little known fact is that you can use graphic symbols and characters in Office 365 labels. It might bring a splash of color to your compliance and retention efforts, especially in a world where emojis are everywhere. After all, the symbols are just character codes that computers can process and Office 365 is designed to be multilingual and cope with different character sets (like the way Teams deals with Hebrew and Arabic).
