Outlook 365 on Windows 10 - "Need Password" - "Click to enter your password for this account."

You need to remove the mail profile and add it back again.

is the xxx@yyy.com.au also the Microsoft account you used for the Windows 10 logon and Office 365 subscription?

Hi Jackie,

You say "You need to remove the mail profile and add it back again."

I have 2 GB in my primary email data:
mincad@pavement-science.com.au.ost in C:\Users\Leigh\AppData\Local\Microsoft\Outlook

Will those emails need to be downloaded again?

I am not 100% sure, but I don't think the xxx@yyy.com.au is the Microsoft account I use for the Windows 10 logon and Office 365 subscription.

Hi Jackie,

I had 3 mail accounts.

Using Control Panel / Mail I was able to remove 2 accounts.
But when I attempt to remove the account that is the default for sending, I get this message:

Account Settings

Before deleting the email account containing your personal mail, contacts, and calendar data, you must create a new location for your data.
To create a new data location, open the Account Settings dialog box, click the Data Files tab, and then click Add.

Sorry, but when I open the Account Settings dialog box in Outlook, I cannot see a Data Files tab?

I also tried adding the 2 deleted accounts.
Automatic setup failed.
I tried Manual setup, choosing Exchange (that's what's used for the default sending account).
Failed also.

Leigh

The quickest way is to just create a new profile, instead of editing your current one. Set default profile to start to this new profile.   

Thanks, Kimputer, for your suggestion.

I have created a new profile.

But I'm stuck trying to add my first email account.

We are using Office 365 accounts.

On the "Add Account" dialog I have chosen (*) Office 365.

I'm locked in a loop, I get this warning:

An encrypted connection to your mail server is not available.
Click Next to attempt using an unencrypted connection.

But clicking Next just keeps looping to the above warning!

What is the version of Windows 10 in your Surface Pro?

It seems to me that the OS is outdated.

Jackie:

Windows specifications
Edition      Windows 10 Pro
Version      1909
Installed on      11/07/2019
OS build      18363.720

Windows Update

Can you check your autodiscover settings? You can also use the hosts trick to point your autodiscover.domain.com to the correct IP address.

Just for the record, I uninstalled and reinstalled Office 365 - made not difference!

Are your Surface Laptop 3 connected to a domain network?

Thanks, Jackie and Kimputer, for your suggestions.

I have decided to do a fresh install of Windows.
