If accounts that can be used to configure and manage an information protection strategy are not properly secured, then the information protection strategy itself can be easily compromised.
Privileged access management enables you to configure policies that apply
=> just-in-time administrative principles to sensitive administrative roles.
For example, if someone needs temporary access to configure an information protection policy, that person would need to go through an approval process to obtain the necessary set of rights instead of having an Azure Active Directory (Azure AD) account with those rights permanently assigned.

After 30 days, Microsoft Office 365 ProPlus will go into reduced functionality mode. When this happens, users will be able to open files but they won't be able to edit them.
As part of the installation process, Office 365 ProPlus communicates with the Office Licensing Service and the Activation and Validation Service to obtain and activate a product key. Each day, or each time the user logs on to their computer, the computer connects to the Activation and Validation Service to verify the license status and extend the product key. As long as the computer can connect to the Internet at least once every 30 days, Office remains fully functional. If the computer goes offline for more than 30 days, Office enters reduced functionality mode until the next time a connection can be made.

You can use the Microsoft SharePoint Migration Tool to migrate files from a file server to SharePoint Online.
The Microsoft SharePoint Migration Tool has a number of filters you can use to define which files will be migrated. One filter setting is "Migrate files modified after". This setting will only migrate files modified after the selected date.
The first phase of a migration is to perform a scan of the source files to create a manifest of the files that will be migrated. You can use this manifest to identify all the files in Share1 that were modified or created during the last 90 days.

Project1: During Project1, the mailboxes of 100 users in the sales department will be moved to Microsoft 365.
Fabrikam does NOT plan to implement identity federation.
All users must be able to exchange email messages successfully during Project1 by using their current email address.
During Project1, some users will have mailboxes in Microsoft 365 and some users will have mailboxes in Exchange on-premises. To enable users to be able to exchange email messages successfully during Project1 by using their current email address, we'll need to configure hybrid Exchange.
A new way to migrate mailboxes in a hybrid Exchange configuration is to use the Microsoft 365 data migration service. The data migration service can migrate Exchange, SharePoint and OneDrive. Therefore, we need to start a data migration and click Exchange as the service to be migrated.
