For the full Teams experience, every user should be enabled for Exchange Online, SharePoint Online, and Office 365 Group creation.

Users' Exchange mailboxes can be hosted online or on-premises. However, some features require a hybrid deployment to be in place with your Office 365 tenant.

Users hosted on Exchange Online or Exchange Dedicated vNext can use all the features of Teams. They can create and join teams and channels, create and view meetings, call and chat, modify user profile pictures (if the Outlook on the web mailbox policy allows them to do so), and add and configure connectors, tabs, and bots.

Users hosted on Exchange Online Dedicated (Legacy) must be synchronized to Azure Active Directory on Office 365. They can create and join teams and channels, add and configure tabs and bots, and make use of the chat and calling features. However, they can't modify profile pictures, manage meetings, access outlook contacts, or manage connectors.

Users with mailboxes hosted on-premises must be synchronized to Azure Active Directory. They can make use of all the features in the above scenario, but additionally they can also change the user profile picture (if the Outlook on the web mailbox policy allows them to do so), and manage meetings, providing Exchange Server 2016 (Cumulative Update 3), or later, is running on-premises with OAuth configured (preferably via the Hybrid Configuration wizard).

The following table provides a helpful quick reference to feature availability based on the Exchange environment.

³ Teams private chat messages are not yet supported for Legal Hold for this hosting option.

⁴ Retention will use a shadow mailbox for the online user to store messages. Microsoft Teams Supports eDiscovery for Teams user in an Exchange Hybrid environment.

⁵ Teams users with on-premises Exchange mailbox may use voicemail with Teams and receive voicemail messages in Outlook, but voicemail messages will not be available to view or play within the Teams client.

⁶ If one of the owners of a team can add connectors, everyone else in that team will be able to do so, even if their mailboxes are homed on-premises.

⁷ Only contacts in default contacts folder. Access to other contacts folders or sub-folders is not supported.

⁸ Teams honors the Outlook on the web mailbox policy setting that's configured by tenant admins to control whether users can change their profile picture. If the -SetPhotoEnabled setting is turned off in the policy, users can't add, change, or remove their profile picture. For example, if a user uploads a profile picture that's approved by your organization's IT or HR department, no action is needed. However, if a user uploads a picture that's inappropriate, change the picture according to your organization's internal policies.

Requirements to get the most out of Microsoft Teams

Microsoft Teams works with several Office 365 services to provide users with a rich experience. To support this experience, you need to enable certain features or services and assign licenses.

SharePoint Online is required to share and store files in team conversations. Microsoft Teams doesn't support SharePoint on-premises.
Users must be assigned a SharePoint Online license if they want to share files in Chats. If users aren't assigned and enabled with SharePoint Online licenses, they don't have OneDrive for Business storage in Office 365. File sharing will continue to work in Channels, but users are unable to share files in Chats without OneDrive for Business storage in Office 365.
Users must be enabled for Office 365 group creation to create teams in Microsoft Teams.
To let Microsoft Teams work with Exchange on-premises, you must configure the new Exchange OAuth authentication protocol as described in Configure OAuth authentication between Exchange and Exchange Online organizations.

Note

For Exchange On-Premises and Teams integration, the required license needs to be assigned for the AAD synced user.

Important

If you uninstall the Skype for Business client after you move a user to Teams Only mode, presence may stop working in Outlook and other Office apps. Presence works fine in Teams. To resolve this issue, select your profile picture in the top right-hand corner of Microsoft Teams and then select Settings. On the General tab under Application, select Register Teams as the chat app for Office (requires restarting Office applications). After you select this option, close and re-open all Office apps, including Outlook. After you open Outlook, presence information will be available.
