Skype for Business Online service description

Note

Microsoft Teams is now the primary client for messaging, meetings, and calling in Office 365. Starting October 1, 2018, new customers with 500 seats or less will be onboarded to Microsoft Teams and will not have access to Skype for Business Online. As of September 1, 2019, this applies to all new customers. Tenants already using Skype for Business Online can continue doing so (including provisioning new users) until they complete their transition to Microsoft Teams.

Note

Skype for Business Online Plan 2 retired from sale on July 1, 2019. This means that you will no longer be able to acquire Skype for Business Online Plan 2 for instant messaging, presence, meetings, and peer-to-peer voice and video. These features will continue to be supported in all plans that include Teams, including Office 365 suites. When your plan expires at the end of your current term, in order to have continued access to these features, you'll have to switch to a different plan. We recommend that you evaluate the Microsoft 365 Business Basic, Business Premium, or any other Office suites for users that currently have Skype for Business Online Plan 2 assigned.

Do you want to know what licenses you need to buy to get certain Skype for Business features? See the Skype for Business add-on licensing.

Skype for Business Online is a communications service that connects people for conversations anytime and from anywhere. It gives users access to information about presence, and enables instant messaging, audio and video calling, and extensive web conferencing capabilities.

Skype for Business is hosted on multi-tenant servers that support multiple customers simultaneously. These servers are housed in Microsoft data centers and are accessible to users on a wide range of devices from inside a corporate network or over the internet.

1 The Skype for Business (Lync) client is supported for use with these subscription options, but it is not included. Lync 2013 Basic is available for all customers. The Lync Basic desktop client is a locally installed application that provides presence, instant messaging, and conferencing features for plans that include Skype for Business Online. Microsoft 365 Apps for enterprise, and Office 365 E3 include the full Skype for Business (Lync) application, which includes additional features such as advanced telephony support, archiving, and compliance features. A Skype for Business Online license must be assigned for each user. For more information on Lync Basic features, see Desktop client comparison tables for Lync Server 2013.
2 Archiving for Skype for Business Online depends on the Exchange In-Place Hold feature, which is not included in this plan.
3 You must assign an Exchange Online (Plan 2) plan to users who you want to have voice mail. An Exchange Online ( plan ) plan can't be used for voice mail.
4 An Office 365 F3 user may participate in a sharing session if invited by a Skype for Business Online Plan 2 or enterprise plan user.
5 Audio Conferencing can be added to Microsoft 365 Business Standard, Office 365 E1, and Office 365 E3 subscription plans as an add-on.
6 Communication Credits can be added to Microsoft 365 Business Standard subscription plan as an add-on to support Audio Conferencing only.

8 Customer Key lets you control your organization's encryption keys and then configure Microsoft to use them to encrypt your data at rest in Microsoft data centers. Data at rest includes data from Exchange Online and Skype for Business that is stored in mailboxes and files that are stored in SharePoint Online and OneDrive for Business. Customer Key helps you meet compliance obligations because you control the encryption keys that Microsoft uses to decrypt data. For more information, see Service encryption with Customer Key.

Feature availability across Skype for Business Online standalone plans

The following table lists Skype for Business Online feature availability across standalone plans. For a description of these features, go to Skype for Business Online features.
