Using Microsoft 365 Groups can be helpful because they work with the Microsoft 365 tools you use already. This enables you to collaborate with your teammates when writing documents, creating spreadsheets, working on project plans, scheduling meetings, or sending emails.
If you are using Microsoft 365 you can convert distribution lists to Microsoft 365 Groups.
Warning: As of February 1, 2023, the feature in the Exchange Admin Center (EAC) and PowerShell that enabled migrating distribution lists to Groups has been deprecated.
You can still follow the workaround process documented by Microsoft to replace your distribution lists with Groups.
