Hi Ian Rendell
Thank you for reaching out to Microsoft Q&A forum and apologize for the inconvenience
However, to better assist you, could you please provide the additional information above:
- When the issue happens on the phone, do Outlook on the web and Teams on the web work normally for the same account?
- Does it reproduce on both Wi‑Fi and cellular (and are you using any VPN/Private DNS/proxy/security/ad‑blocker)?
- What are the exact versions: Android OS + Outlook/Teams app versions + Android System WebView/Chrome? (Blank/white screen issues can be version-specific.)
Please review the suggestions given by Q&A Assist first and if those steps do not help you fix the issue, consider checking my questions above and provide more information so I could assist you better.
I am looking forward to hearing from you.
