Outlook on iPhone 16

Question

Outlook on iPhone 16

Shane Cooley 20

I have all of a sudden been unable to access my emails using the Outlook App. I've removed it from the iPhone and reinstalled it, but am unable to access my account. If I use the Mail app I can access the Outlook account but it continually updates and won't let me create an email. Apple have been unable to help and have advised I speak with Outlook. Can you help? Cheers, Shane

Hello Shane Cooley,

First: confirm the account still works online: https://outlook.live.com/

Open https://login.microsoftonline.com/ & Sign-in

Reinstall Outlook again

Restart iPhone

Do you get an error message in the Outlook app? If yes, what exactly does it say?

Regards,

Hello Shane Cooley

I understand how frustrating it must be when Outlook suddenly stops working on your iPhone, especially when it was working fine before.

First, could you please confirm:

Are you using an Outlook.com/Hotmail account or a third-party (Gmail, Yahoo, etc.) in Outlook?
Do you see any error message when signing into Outlook app?

In the meantime, please try the following:

1, Remove and re-add account properly in Outlook app

Instead of just reinstalling the app:

Open Outlook app > tap profile icon
Go to “Settings”
Go to "Account" > select your account > tap “Delete Account”
Restart your iPhone
Re-add the account using “Add Account”

2, Reset iOS Mail account (for Apple Mail issue)

Since Apple Mail is also behaving oddly:

Go to iPhone “Settings” > “Mail” > “Accounts”
Remove your Outlook account
Restart the device
Add it back

3, Check for iOS / Outlook app updates

App Store > update Outlook app
Settings > General > Software Update

Outdated builds can cause sync loops or sending issues.

Please feel free to let me know how it goes after trying these steps. Thank you for your understanding.

Hi, I tried doing as you advised and opened the Outlook app. I was asked to add my account that was already highlighted and couldn't access the 'Settings'. I clicked on my account and it just opened up without anything else being touched. I'll keep these instructions in case I have a problem again, but it appears that time was needed for it to settle. Cheers, Shane

Hi Shane Cooley

Thank you for the update. I’m glad to hear it’s working again.

It’s possible the app just needed a bit of time to re-sync and stabilize after the reinstall. That can sometimes happen with mobile apps, especially after account re-setup.

If the issue comes back, feel free to reach out again and I’ll be happy to help further.
