Microsoft 365 MS-100 Microsoft Study Notes

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.

Fabrikam plans to create a group named UserLicenses that will manage the allocation of all Microsoft 365 bulk licenses.

The memberships of UserLicenses must be validated monthly. Unused user accounts must be removed from the group automatically.

The group needs to be a Security group.

Azure Active Directory (Azure AD) access reviews enable organizations to efficiently manage group memberships, access to enterprise applications, and role assignments. User's access can be reviewed on a regular basis to make sure only the right people have continued access.

Fabrikam plans to implement a Microsoft 365 Enterprise subscription and move all email and shared documents to the subscription.

All users must be able to exchange email messages successfully during Project1 by using their current email address.

After the planned migration to Microsoft 365, all users must continue to authenticate to their mailbox and to SharePoint sites by using their UPN.

This configuration requires a hybrid Exchange configuration during the pilot phase. This means that you will have mailboxes hosted in Exchange Online and mailboxes hosted in Exchange on-premise.

The first steps to configure Exchange hybrid are to Create the Azure AD tenant, add the Fabrikam.com domain as a custom domain, then configure directory synchronization to replicate the on-prem Active Directory user accounts to Azure Active Directory.

Box 1:

Office 365 ProPlus feature updates will be installed twice a year in March and September.

The Channel element in the configuration file is set to ‘Targeted’. This means Semi-Annual Targeted.

To help your organization prepare for a Semi-Annual Channel release, Microsoft provides Semi-Annual Channel (Targeted). The primary purpose of this update channel is to give pilot users and application compatibility testers in your organization a chance to work with the upcoming Semi-Annual Channel release

Box 2:

Microsoft Office 365 ProPlus applications must be installed from a network share only.

The AllowCDNFallback value is currently set to true. The purpose of this setting is to enable Office 365 to be downloaded from Microsoft’s Content Delivery Network if the network share is unavailable. The AllowCDNFallback value should be set to false to meet the technical requirement.
