About This Article
This article was created using an automated generation workflow utilizing generative AI. Based on Microsoft Loop license documentation and support information, it organizes the concepts of the Loop app and Loop components in Microsoft 365 E3/E5.Validation Status: 📘 Official information verified. Some license displays require verification per tenant. Actual device testing not conducted.
Microsoft Loop is a co-authoring tool that uses pages, workspaces, and Loop components to share and develop information in small pieces among multiple users. It is suitable for gathering "unsettled information" that is difficult to handle using only completed Word documents, Teams conversations, or Planner tasks.
Understanding Loop in Three Categories
Because Loop can be difficult to understand when viewed as a single entity, it is broken down into the following three components:
Loop component : Teams/Outlook等でも共同編集できる小さな部品 Loop page : 複数の部品や文章をまとめるページ Loop workspace : 関連ページをまとめる作業場所
Positioning in M365 E3/E5
Microsoft provides usage rights for Loop based on subscriptions and feature units. While Microsoft 365 E3/E5 is an eligible plan for using the main features of the Loop app, Loop components are also subject to the conditions of the host services being used, such as Teams, Outlook, and Whiteboard.
Additionally, information regarding the "Extra Features" display from the older Public Preview era and differences from Office 365 E3/E5 still exists on the web. Make sure to check whether your current subscription is Microsoft 365 E3/E5 or Office 365 E3/E5 in the admin center before making a decision.
| Verification Item | Approach in M365 E3/E5 |
|---|---|
| Loop App | Verify as an eligible plan |
| Workspace Creation | Verify current Loop licensing conditions |
| Loop Components | Verify conditions for host apps like Teams and Outlook |
| Copilot in Loop | Verify additional conditions such as Microsoft 365 Copilot separately |
When to Use Loop
Organizing discussion points before starting a project
Gathering information from participants before a meeting
Collaborative note-taking before finalizing specifications or ideas
Collaboratively updating tables buried in Teams chats
Consolidating multiple small pieces of information into a single workspace
Loop becomes easier to use when you separately designate where information goes once it is finalized—such as Word/SharePoint for official regulations and confirmed documents, and Planner for tasks with clear assignees and deadlines.
Getting Started: A Three-Item Collaborative Note
If you have an environment where you can create test workspaces and pages, set up only the following three items:
目的 確認したいこと 次のアクション
Add three checklist items under "Items to Check" and share the page with one test collaborator.
Check the Following
Changes made by the other person are reflected on your screen
You can verify the extent to which you can track who made edits
Content remains even after closing and reopening the page
The shared recipients are limited to the intended people
Try Changing One Element
Change one checklist item into a table and add an "Assignee" column. A key characteristic of Loop is the ease of modifying information structures on the fly.
Prompt for Generating a Draft Loop Page with Generative AI
新しいプロジェクトのLoopページを作ります。 次のメモを「目的 / 決まっていること / 未決事項 / 次に確認すること」の4つに分類してください。 元のメモにない決定事項は追加せず、推測は「推測」と明示してください。 [メモ]
Because Loop often handles intermediate information, explicitly instruct the AI not to turn assumptions into established facts.
Best Practices for Business Use
Do not treat "writing in Loop" as an official decision
Decide where to move the official record of finalized items
Avoid creating too many workspaces
Check tenant settings for external sharing and guest access
Verify storage, sharing, and compliance conditions when handling confidential information
Test permission relationships between components within Teams/Outlook and the Loop app
Points for Administrators to Verify
Whether the assigned SKU is Microsoft 365 E3/E5 or an Office 365-based plan
Assignment of the Loop service plan
Storage and sharing conditions on SharePoint/OneDrive
Licenses for host applications such as Teams and Outlook
Additional licenses when using Microsoft 365 Copilot
Current support scope for management and compliance features

Loop is a continuously updated service. Please verify your contracted SKUs and tenant settings as of September 17, 2026, and avoid assuming that all features are available simply because "Loop is visible on the screen."
