Hi @Bilbeisi, Mohd,
Thank you for reaching out to Q&A Forum.

With Outlook errors 5objp and 5ssai, these errors typically occur during sign-in on Android or iOS devices, especially after device migrations, app updates, or when cached credentials conflict with the authentication flow.

In order to assist you with accuracy, could you provide me with some additional information related with your issue?

Which type of account are you using with Outlook? Is it a personal account (e.g., @outlook.com, @hotmail.com, @gmail.com) or a school/work account managed by your organization?

Have you tried signing in to the Outlook Web App (OWA) through your browser?

Once I have a clearer understanding of your current situation, I’ll be happy to assist you with greater accuracy. Please feel free to share any additional details you believe are relevant. Screenshots are especially helpful and much appreciated.

In the meantime, I'd recommend you clear your device cache credentials first to ensure proper sign-in:

1. Remove old accounts from device settings
   • Go to Settings → Accounts → Manage accounts.
   • Delete any duplicate or old Microsoft/Work accounts.
2. Clear Outlook app cache and data
   • Settings → Apps → Outlook → Storage → Clear Cache & Clear Data.
3. Reinstall Outlook
   • Uninstall Outlook → Reboot → Reinstall from Play Store/App Store.
4. Sign in using the full UPN format
   • For school accounts, use your organization’s domain.
   • This forces a fresh authentication session.
