Disable email account synchronization with Microsoft Cloud service

Hello,

some time ago, I configured my company email account in the New Outlook for Windows. At one stage of the setup, it was necessary to agree to synchronize emails, contacts and events with the Microsoft Cloud service. I only used New Outlook for Windows for about a dozen minutes, after which I removed the previously configured email account and then uninstalled the application. I point out that the aforementioned email account is not associated with any Microsoft Account or set as auxiliary email address.

After a few days, I configured two-factor authentication for my company email account, and since then the account has been blocked from time to time due to failed login attempts coming from Microsoft servers located in Amsterdam or Vienna.

How can I disable the synchronization or completely remove the association of my company email account with Microsoft Cloud service so that the login attempts from the aforementioned servers will stop?

Hello GT84_01,

Greetings!

Thank you for posting on Microsoft Community!

I've read your issue description carefully, in order to resolve your issue in a timely manner, we'd suggest you to check the following:

Since you mentioned emails, contacts and events were set to be synchronized, you may try to turn off Microsoft account settings on your computer:

1. Click the Windows Start button and open Settings.

2. Browse to Accounts and select Sync your settings.

3. Toggle off the Sync settings switch to turn off Microsoft sync.

4. Go to Access work or school and click "Disconnect" on the company email account.

5. There should be only one company email account on your New Outlook for Windows applicantion.

After you disconnect and remove the Company Microsoft account from account settings, it should be good to login it with two-factor authentication on the New Outlook.

Please share the result to us after following above mentioned steps, we will continue to support you!

Appreciate your patience and understanding and thank you for your time and cooperation.

Hello Eleni,

thank you for your quick response and suggestions you sent leading to resolve the issue. Below I attach screenshots showing settings of user accounts on my computer.

1. Accounts - I've got the local administrator account only, so my emails, contacts and events are not syncing.

Image

2. Windows backup - sync is disabled

Image

3. Access work or school - no accounts added

Image

4. Email & accounts - no accounts added

Image

5. New Outlook for Windows startup screen - no accounts added

Image

Even though I don't currently have an email account in the New Outlook for Windows added should I add one and login it with two-factor authentication and then remove it?

Will this stop attempts of my business email account syncing with MS Cloud server I’ve mentioned in the first post?
