【 Office365 アップデート 】Outlook mobile における会議ソリューションの展開

Office365 に関する Major Change Update 情報(2019/3/5付)をご案内いたします。

先日、下記の記事でご紹介した ” iOS と Android で展開している『 Outlook mobile 』から、Teams の会議作成/参加がシームレスにできるようになる” という Update の続報です。


特に注目しておきたいポイントは、Teams 管理センターにおける『 Coexistence mode 』の設定に応じて、『 Outlook mobile 』で会議する際に使われるソリューションが異なる( Teams or SfB )点です。何かあった時のためにも、この違いは押さえておきたいところですね。なお、詳細につきましては、下記 ”Nortification” の中段に掲載している表をご覧ください。

We recently announced that we will be rolling out native support for creating and joining Microsoft Teams in Outlook for iOS and Android (MC173895). GCC High and Department of Defense organizations did not receive the original announcement. Based on your feedback, we’re providing more clarity, additional flexibility to the roll out plans and expanding the audience.

This enhancement is related to Microsoft 365 Roadmap ID 32955 and 32956

The roll out of Teams in Outlook mobile will take into consideration your organization’s plans to upgrade to Teams. The experience in Outlook mobile will be based on how you have set your coexistence mode between Teams and Skype for Business in the Microsoft Teams admin center or in PowerShell (Grant-CsTeamsUpgradePolicy), at the tenant level and/or for the user.

We will start to roll out these changes at the beginning of April 2019 and will support Office 365 Monthly Channel customers world-wide as well as US Government Community Cloud (GCC) customers including GCC High and Department of Defense.

[How does this impact me?] The experience for Teams Meetings in Outlook mobile will be based on how you set the organization’s or individual users’ Teams and Skype coexistence mode based on the following:

Coexistence mode in Teams Admin Center Meetings solution in Outlook mobile
Teams Only Teams
Skype for Business with Teams Collaboration and Meetings* Teams
Skype for Business with Teams Collaboration* Skype for Business
Skype for Business Only Skype for Business
Islands Skype for Business

The experience in Outlook mobile will be based on this coexistence mode setting at the tenant and the user level. The user level setting, if present, will take precedence over the tenant level setting. For example, regardless of the tenant level setting, if a user’s coexistence mode is “Teams Only” or “Skype for Business with Teams Collaboration and Meetings”, then they will be able to add Teams meetings instead of Skype for Business when creating Outlook mobile events.

Similarly, if a user’s coexistence mode is “Skype for Business Only”, “Skype for Business with Teams collaboration”, or “Islands”, then nothing changes. They will continue to have the option to add Skype for Business meetings in Outlook mobile.

In addition, for customers who have also started to use the Microsoft sync technology for Outlook mobile (MC165218), we’re introducing a new Teams Join button in calendar events. This makes it easy to Join a Teams meeting and will be available for all coexistence modes as users could be invited to Teams Meetings even if they are not enabled to create Teams meetings themselves. Customers who are not using the Outlook mobile sync technology yet will continue to be able to join Teams Meetings using the weblink in the meeting description.

Note that the addition of the Teams Join button does not replace the Skype Join button. The Skype Join button will continue to be offered for Skype Meetings, and the Teams Join button will be offered for Teams Meetings.

[What should I do to prepare for this change?] There is nothing you need to do to prepare for this change however you may want to check your organization’s settings for Teams coexistence by April 1st, 2019 to be sure it is set to fit your organizational needs when we roll out these changes or if you wish to set preferences for certain groups of users within your organization.
