Few people in our Organization are facing issue with Copy paste in Browser(Edge and Chrome)

Copy and paste issues in Edge and Chrome can be caused by several protection and clipboard-control features on Windows 11 and in Microsoft 365. From the described behavior (Windows security popup, Sense service involvement), this is likely tied to endpoint protection / DLP controls that inspect clipboard content before allowing paste.

Relevant clipboard-related behaviors and controls include:

1. Browser clipboard permissions
   • If users see messages like “No clipboard access” or copy/paste fails in Office on the web, check site-specific clipboard permissions in Edge and Chrome.
   • In Edge:
     1. Select the lock / “View site information” icon in the address bar.
     2. Under “Permissions for this site”, locate Clipboard.
     3. Set it to Allow.
   • In Chrome:
     1. Select the “View site information” button in the address bar.
     2. Locate Clipboard.
     3. Toggle it On.
2. Intune app protection / copy-paste restrictions
   • If Intune App Protection Policies are in use, copy/paste between managed and unmanaged apps can be restricted.
   • For users who can’t paste from managed apps (like Outlook) into other managed apps or browsers, verify the Restrict cut, copy, and paste between other apps setting:
     • If set to Blocked, users won’t be able to paste between managed apps.
     • If set to Any app, pasting to other apps is always allowed.
     • Recommended for typical enterprise scenarios:
       • Policy managed apps: allows copy/paste only between managed apps.
       • Policy managed apps with paste in: allows paste into managed apps from unmanaged apps, but blocks paste out to unmanaged apps.
   • Also ensure the destination document is opened from a managed location (for example, OneDrive for Business or SharePoint Online), because app protection policies don’t apply to unsaved new documents.
3. Endpoint DLP “Paste to browser” controls
   • If Microsoft Purview Endpoint DLP is configured to restrict paste into browsers, users may see delays or blocks when pasting into Edge/Chrome.
   • In the DLP policy:
     • Under Actions → Audit or restrict activities on devices → Service domain and browser activities → Paste to supported browsers, the action can be set to Audit, Block with override, or Block.
     • A strict Block configuration for the target domains will prevent paste; Block with override will show a prompt; Audit will only log.
   • Classification latency can cause a delay between paste attempt and policy decision, during which users may see multiple notifications.
   • To reduce issues, guidance includes:
     • Configure overall action to Audit and selectively Block only specific sites via exceptions, or vice versa.
     • Ensure the latest antimalware client and Edge versions are installed, and required Windows KBs are applied.
4. Protected Clipboard in Edge for Business / Intune MAM
   • If Protected Clipboard is enabled for Edge for Business, copy/paste is governed by a “trusted boundary” (for example, the Edge work profile or defined managed cloud apps).
   • Behavior:
     • Within the trusted boundary: copy/paste between managed web apps is allowed.
     • Crossing the boundary (for example, to personal tabs, unmanaged apps, or GenAI tools): paste is silently blocked, or users see messages like “Your organization’s data can't be pasted here.”
   • For organizations using Microsoft 365 E3 with Intune MAM, the trusted boundary can be the Edge work profile. Copy/paste is then restricted to that profile; attempts to paste outside are blocked.
5. Windows App / browser clipboard behavior
   • When using Windows App in a web browser (for remote desktops), copy/paste may not initially work via right-click context menu because the app doesn’t have clipboard access until a keyboard copy/paste (Ctrl+C / Ctrl+V) is performed.
   • After using keyboard shortcuts once, the paste option becomes available.

Given that the issue appears only for some users and is tied to security prompts and a service (Sense) not running, the most likely root cause is a security/inspection service that must be running to evaluate clipboard operations (for example, endpoint protection or DLP). If that service is stopped, the security dialog may hang and effectively block paste.

Remediation at a high level:

1. Verify browser clipboard permissions for the affected sites in Edge and Chrome.
2. Review Intune App Protection Policy settings for Restrict cut, copy, and paste between other apps and adjust according to the intended managed/unmanaged boundary.
3. Review Purview Endpoint DLP policies that restrict Paste to supported browsers, and confirm whether they are set to Block or Block with override for the affected users/sites.
4. For environments using Edge for Business with Protected Clipboard or Intune MAM work profiles, confirm that the observed behavior matches the configured trusted boundary and that users are operating within the intended profile.
5. Ensure required security services and agents (including those used by DLP/endpoint protection) are running on affected Windows 11 devices so that clipboard operations can be evaluated instead of hanging.
