Using Outlook for iOS for personal email and calendar management
Hi, @saki aono
To help narrow this down:
- Are these newly added email accounts on your iPhone, or were they previously working in the Mail app?
- Does this affect only Outlook/Hotmail accounts, or other email providers as well?
Microsoft has documented an issue affecting Outlook and Hotmail accounts in the iPhone/iPad Mail app. Please check this article for more information:
In the meantime, have you tried adding the affected accounts to the Outlook mobile app? Here's the link to try https://aka.ms/OutlookMobile
