You can use a public folder to store and share global email contacts, but a better approach is to use Exchange mail contacts. These objects show up in the Exchange GAL and OAB and are available to all Outlook clients (and some third-party clients too).
Exchange Online distribution lists can be used to populate the membership of Office 365 Groups or Teams by applying a little PowerShell magic. Here’s how.
A recent correspondent asked how to find inactive distribution lists in Exchange Online. We didn’t have a good answer in the book, so here’s some PowerShell code to do the trick.

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.
