Issues by Category
Loop workspaces disappeared from the list
In December 2025 a long-time user said several workspaces with dozens of pages vanished and left orphaned pages. They reappeared on their own six days later with no explanation, and the user said they had lost trust in Loop.
Loop pages fail to sync and show an error dialog
Users report a sync error on web, desktop and mobile that affects one page while others from the same template work, plus pages whose edits do not appear in the web version. Microsoft staff asked for tenant details and recommended a support ticket rather than naming a fix.
Loop agenda components stopped showing in Teams and Outlook meetings
From mid-December 2025 users in tenants of different sizes reported that 'Add an agenda' in Teams created content that existed only in Loop and did not appear in the meeting invite. A Microsoft moderator could not reproduce it consistently and no official cause was published. One organization said it cleared on its own in late January 2026 while another still had it in mid-January.
Loop components not showing up in Outlook and Teams calendar
Several Microsoft Q&A threads describe the Loop option missing in Outlook, components that vanish after being pasted, or components that no longer appear in the calendar. Causes named by moderators include admin policy, outdated Outlook builds and blocked endpoints, and one admin fixed it by allowing substrate.office.com.
Loop says 'unable to connect' and keeps retrying
A Q&A thread opened in January 2024 describes Loop failing to connect in Chrome, Firefox and Safari, and later replies from August 2024 report the same on work, home and VPN networks. The thread was locked with no confirmed fix or allowlist from Microsoft.
No bulk export or built-in backup for Loop workspaces
Users export pages one at a time as PDF, which cannot be re-imported. Re-importable backup means downloading the .loop files from OneDrive or SharePoint, or admins using Purview eDiscovery. A Tech Community reply calls Loop a poor fit for business-critical documentation because of this.
Loop overlaps with OneNote, SharePoint and Planner
Reviewers note that Loop sits on top of tools Microsoft 365 already has, which makes it unclear what to use for what. A G2 reviewer also says its usefulness depends on the whole team adopting it, and another says it takes time to get used to.
Loop storage counts against your Microsoft storage quota
Since mid-2024 Loop workspaces and pages count toward a personal user's Microsoft storage quota, and Microsoft warns that exceeding it can stop email sending and receiving. For organizations, Loop counts against the tenant's SharePoint storage quota.
Copilot in Loop needs a separate paid Copilot license
Loop itself is bundled with Microsoft 365, but Microsoft says Copilot features in the Loop app require a Copilot plan for work or school accounts, and are not available at all with personal accounts, even with Microsoft 365 Personal, Family or Premium.
Why is Microsoft Loop so slow with big workspaces?
A user in a company workspace reported very slow loading and 'wait or close page' prompts, and a third-party review analysis cites workspaces taking over 30 seconds to open. The sync error thread from January 2026 stayed unresolved and other users in the same tenant reported the same behavior.
Can't create Loop workspaces on a personal Microsoft account
Personal accounts get only the Loop app (web, iOS, Android) and Microsoft states that components are not supported in Teams, Outlook or other apps with a personal account. Users with Microsoft 365 Family report that creating a workspace fails with a 'couldn't save your work' error, with a moderator pointing to account setup, storage limits or alias problems.
People emailed a Loop component have to request access
A Tech Community post says recipients of an Outlook email containing a Loop component could no longer edit it and had to request access, where previously adding them to the email was enough. The post has no replies and no confirmed cause. Microsoft's docs say components shared in Teams are always editable, and sharing rules differ by where the component was created.
Loop task lists do not stay in sync with Planner and To Do
Threads from 2024 describe assignees and bucket moves missing, bulk-pasted tasks arriving empty and the last task duplicated more than ten times. A Microsoft staff reply notes only Task Lists sync, not progress trackers. A third-party review says that Loop to Planner sync creates a new plan per component, reported since at least October 2025.
No real databases like Notion: boards and databases only as embeds
Comparison write-ups say Loop has no equivalent to Notion's relational databases and that Kanban boards and databases have to be embedded from other products. A forum user who tried Loop because it came with Microsoft 365 Family went back to Notion.
Regret Patterns
Common reasons users regret choosing Microsoft Loop.
Built the team wiki in Loop and then found export is limited
Users move notes and docs into workspaces, then discover there is no bulk export and PDFs cannot be re-imported. Re-importable backups rely on .loop files in OneDrive or SharePoint or admin tools.
Relied on meeting agenda components that stopped working
Teams made the Loop agenda part of every meeting, then the component stopped appearing in the invite from December 2025 for many tenants, forcing manual link sharing.
Expected components to work with a personal Microsoft 365 plan
People with Microsoft 365 Family try Loop because it is included, then find components do not work in Teams or Outlook with a personal account and Copilot is unavailable.
Went back to Notion for databases
One user tried Loop to cut app count since it came with Microsoft 365 Family and returned to Notion for what Loop lacked.
Lost trust after workspaces vanished
A long-time user saw workspaces disappear for days with no explanation and said they no longer trusted Loop for important work.
When Microsoft Loop Breaks Down
Specific scenarios where Microsoft Loop fails or underperforms.
Admin disabled Loop in one place but not the other
Microsoft requires both Cloud Policy and SharePoint PowerShell settings for full control. Teams components use Set-SPOTenant IsLoopEnabled while Outlook uses Cloud Policy, so users see Loop in one app and not the other.
Organization uses conditional access or mailbox policies
Outlook on the web and the new Outlook for Windows need certain OWA mailbox policies set to true, and sessions that match conditional access have limited functionality and cannot use Loop components by design.
Workspace owner leaves the company
The workspace becomes ownerless and members cannot delete it until an IT admin adds new owners; a personal workspace follows the OneDrive deletion lifecycle.
Task lists edited in both Loop and Planner
Back-and-forth edits led to missing assignees, empty bulk-pasted tasks and duplicated tasks in reports.
Personal account storage fills up
Loop pages count toward the Microsoft storage quota and Microsoft warns that exceeding it can stop email.
Large company workspace with many pages
One user suspected too much content in a workspace after very slow loading and wait prompts; their sync error stayed unresolved.
