Windows 10: Finding which Office 365 system has my personal email address as a logon?

When I try to logon to Microsoft systems, I get this prompt:




I'm quite aware what triggers this - accounts whereby there is both an Office 365 account and Microsoft account using the same email address.


Except, that's my personal email address which is not used anywhere (to my knowledge) as an Office 365 system logon. I've checked the six Office 365 systems used by my client and it's not in there - well obviously.


It could be that it was used in a trial of Office 365 a few years ago when I was doing some research/learning but that trial has long since expired so I can't access it.


When I try to logon using the work address, it rejects the password and when I go through the reset password, it says the account doesn't exist:




So something has got very confused here. Obviously, when I enter my personal email address, Microsoft is checking something to think I've got a work and personal account. However, as an end user, I can't work out what other system it thinks I've got an account with.


I don't want to rename my personal account BTW as I use that all the time.


Is there anyway Microsoft can delete this work address for me? I don't want it...

How to enable 'send as' in Outlook (Office 365 email)


Both. In OWA (web app) the users need to select Show from:




When doing this first time, the new allowed Send As email is not shown in the From drop down list. Users need to right click their usual Send As address and select Remove, then add the new Send As address manually:




After that the new address will be shown and can be selected from the drop down list.

In Outlook desktop app users need to manually remove their usual Send As address and add the new one, thereafter the new address will be shown in From drop down list.

 

Office 365 for students

Its possible you need to download the software install files from the schools website if you purchased it through the school.

• Please uninstall any Office trial versions on your device before installing Office 365 Education.
• Open the Microsoft Office 365 Web site.
• On the Office in education screen, enter your IT Account NetID, followed by <university email
  address> and click Get Started.

  University services.

 

Cortana & Office 365 Integration

We are trying to integrate Cortana with our Office 365 subscription, but it never works. Here are the steps we have done:

• Turned on Cortona in the Office 365 Admin portal
• We are using Windows 10 1703 – connected Office 365 service to Cortana

Did the same on windows 10 mobile with no luck, Cortana says its connected to Office 365, but sees no data and we are getting zero errors

We went rough office 365 support first and tried all fo their suggestions, they kicked us over to Windows support which is currently closed.

We are on v1703 with all updates in place, it does not work on Windows 10 desktop or mobile

any ideas? I can give you all steps 365 support had us run through if that will be helpful

Thank you
