Outlook rejecting new IONOS email password

Question

Outlook rejecting new IONOS email password

Frogger 20

Hi, I transfered my Outlook email to IONOS due to a hack that couldn't be resolved by MS.

I am trying to upload this new email to Outlook, but it is being rejected at the password stage I guess because it wants my old password or the Hacker's one.

How do I get Outlook to look for the IONOS email and password. It is the same email address?

I have deleted my old email i.e. 'forget' from Office 365 profile. But that hasn't worked either. Do I need to wait a day and try again? I am working from a new computer, so no saved passwords on it.

Thanks in advance.

Hi @Frogger

To make sure I understand your situation correctly, may I clarify the following?

Does your IONOS subscription also include a Microsoft Exchange mailbox?
What type of IONOS account do you have? Is it a POP, IMAP, or Exchange account?
What is the original type of your Outlook account? When you sign in to Outlook on the web, do you notice whether the URL contains "live", "consumer", or "microsoftonline"?

If I’ve misunderstood any part of your situation, or if you have further questions or updates, please don’t hesitate to reply.

Thank you for your time, and I look forward to hearing from you soon.

Hi, let me check with IONOS team and revert back to you.

RE: 3. I can't sign into my Outlook email account as it has been hacked and MS can't/won't recover it - hence I have changed my email to an IONOS email. I will see if I can see this on my 365 admin account.

Kind Regards, F

Hi, I've spoken to IONOS and they have informed me of the following answers to your questions:

Does your IONOS subscription also include a Microsoft Exchange mailbox?

IONOS: No.

What type of IONOS account do you have? Is it a POP, IMAP, or Exchange account?
IONOS: They said that they would expect it to be IMAP but they can't tell as this would be a part of my set up with Outlook

What is the original type of your Outlook account? When you sign in to Outlook on the web, do you notice whether the URL contains "live", "consumer", or "microsoftonline"?

I haven't been able to confirm this but I could get in and delete the email account from Office 365.

I will try to reload it later tonight.

However it still looks like the hacker is sitting in my profile - that will be my next challenge to delete them!

Hi @Frogger
Thank you for your update.

Since you mentioned the Microsoft 365 Admin Center, I understand that the compromised account is a work or school account rather than a personal Microsoft account.

Regarding your IONOS account, you may try creating a new Outlook profile by following the guidance in Create a new Outlook profile.

After that, please add the account as an IMAP account by following the provided steps.

For the incoming and outgoing mail server settings, I recommend contacting the IONOS Support Team to obtain the correct configuration details

As for the compromised account, please refer to the following Microsoft documentation for the recommended next steps: Respond to a compromised email account in Microsoft 365 - Microsoft Defender for Office 365 | Micro…

I hope this information provides additional insight.
