Office 365 Outlook vs Exchange Outlook

This document is informational to highlight some of the differences you will see when Outlook is changed from the Exchange configuration to the Office 365 configuration. Most notably are the addition of several features that are not available in the Exchange configuration. Below you will see those differences highlighted between the screenshots of the two configurations. This is to prepare you for possible questions that may arise once the migration is complete and users are reconfigured to use Office 365 Outlook. One of the key features in the Office 365 configuration is the ability to "get add-ins" versus the Exchange configuration being more limited in that respect, and on a Mac no add-ins are available without a great deal of effort.

Overall, the additional features that become available when the Office 365 configuration is applied are pretty self explanatory. Get add-inns give the user the ability to browse available add-ins for Outlook; Share to Teams give the user the ability to share items to Teams directly from Outlook, if they have Teams installed, users can report Phishing and spam; manage senders, and manage on hold emails right from the ribbon in both Mac and PC versions of Outlook. They differ primarily in cosmetics/layout/look while offering nearly identical functionality. 

Mac

The second screenshot is the "current" Outlook. You can clearly see there are significant differences in each, but both are using the Office 365 configuration. Below these first 3 screenshots you will see PC screenshots that highlight the differences as seen with both configurations in Windows.

This screenshot is of Outlook on a Mac, but this is the Exchange configuration. Users who are currently using Outlook on a Mac will see something very similar, if not identical to this screenshot. As you can see the features here are fewer than what the "current" Outlook above has. 

PC
