Admin Tips and Shortcuts
1

Applies to

  • SharePoint Online
  • Custom SharePoint applications / SPFx solutions
  • Mobile browsers or in-app web views (iOS / Android)

Symptoms

When accessing a SharePoint site from a mobile device using a custom application or mobile browser, users may see:

Something went wrong
Technical Details: ERROR: [object Object]

The same site typically loads correctly:

  • On desktop browsers
  • For Global Admins or privileged users

Root Cause

This issue is most commonly caused by Azure AD / Entra ID Conditional Access policies that restrict mobile or browser-based access to SharePoint Online.

Because the error occurs after authentication, SharePoint may surface a generic message instead of a sign-in prompt.

Common Conditional Access Triggers

One or more of the following policies may apply:

  • Blocked Mobile & Desktop Clients
  • Device compliance required
  • Approved client app enforcement (Intune)
  • Restrictions on unmanaged or browser-based devices
  • Blocked embedded or webview authentication

These policies frequently affect:

  • Mobile browsers (Safari / Chrome)
  • Custom SharePoint applications
  • Embedded web views inside mobile apps

How to Confirm

  1. Go to Azure AD / Entra ID → Sign-in logs
  2. Filter by:
  • User
  • Application: SharePoint Online
  1. Review failed sign-ins and check:
  • Conditional Access status
  • Policy name applied

If a Conditional Access policy shows Failure, it is the cause.

Recommended Remediation

Depending on the organization’s security posture, administrators may:

  • Allow Browser client access for SharePoint Online
  • Exclude SharePoint Online from specific Conditional Access rules
  • Exclude affected users or security groups
  • Adjust device compliance requirements for browser access
