Problem with loggin in DepEd outlook account teams in phone

Hi @cymm

Thank you for posting your question in Microsoft Q&A. 

As your description, the error "AADSTS90023: An error occurred while processing incoming "message when attempting to switch organizations within the Microsoft mobile application. Notably, this functionality continues to work as expected on your PC, and the issue appears to be isolated to mobile devices. 

If it possible, could you try to follow these steps to troubleshoot it: 

1. Clear Cache and Reinstall the App: Application on your phone might be storing old or corrupted session information, which is causing the authentication failure. 

• Go to your phone’s settings → Apps → Microsoft Teams → Storage → Clear Cache and Clear Data
• Uninstall and reinstall the application. 

This resolves corrupted local data that may be interfering with authentication 

2. Check Guest Organization Access 

• On your laptop, go to Teams → Settings → Accounts and Orgs. 
• Confirm that the organization you're trying to switch to is listed and accessible. 
• On mobile, this list may not fully sync. If you only see one org, it could be a sync issue. 

3. Verify Conditional Access Policies 

• If your organization enforces Conditional Access (CA) policies, especially MFA or device compliance, these may block access on mobile. 
• Mobile apps sometimes fail to meet compliance checks that desktop apps pass.
