Hotmail is my main email account.
Was getting emails to phone up til this morning. Was too busy all day to realise I didnt get any emails, and when I got home and back into wifi, I realised not one had dowloaded since 8.30am
I tried to refresh, but it says incorrect username or password.
Then I went into account settings, and incoming server settings.
I re entered my password nad keep getting this message:
Internal error
An error occured, please try again (100)
I can access hotmail via the browser, just not through the email icon.

Anyone have any ideas?

So I deleted the 3 hotmail accounts from the phone, and tried to set up again. I repeatedly got the message: connection failed.
I dowloaded the hotmail app and have now set up push email through there.
Doesn't explain why my social hub hotmail accounts have suddenly failed though. My gmail is coming through ok though.

Hi, I get the same error when i log in to Hotmail and Gmail. I thorght it was a phone fault but its strange im not the only person with this problem. Ive since deleted hotmail from social hub but cant reinstall it now.

Hmm, wonder if it's got anything to do with Hotmail's new Outlook switchover?
Try downloading the app. at least you will get your emails.

yes i will do that, Its strange my gmail is telling me the password is incorrect at the same time. Only affecting my Social hub Gmail tho.

Have you tried downloading the Hotmail app from Google/Android Market?
