Your company has 100 user mailboxes. The company purchases a subscription to Office 365 for professionals and small businesses. You need to enable the Litigation Hold feature for each mailbox. What should you do first?

The first step will always be the purchasing the correct Office 365 plan to suit your needs. There are three plans of Office 365: Professional, Mid-Size Businesses, and Enterprise. The Office 365 Mid-sized businesses and Enterprise plans will allow you to enable Litigation Hold. The Professional plan is not compliant with this setting. User mailboxes that are placed under litigation hold with the external audit enabled meet all compliance requirements, because the data is immutable.
