Thank you for that information, @kjr53484!

Just as our ACE @JefferMC mentioned, you will receive errors if you are not using a Secure Mail Key. You can take these steps to create one:

1. Go to Profile and choose Sign-in info.
2. Select the email account that needs a secure mail key. (You’ll find a menu at the top if you have multiple accounts.) 
3. Scroll to Secure mail key and select Manage secure mail key.
4. Choose the email address that you’d like to use, if you have more than one.
5. Select Add secure mail key and then enter a nickname for the secure mail key to make it easier to recognize.
6. Choose Create secure mail key.
7. Select Copy secure mail key to clipboard. Make a note of your secure mail key, so you have it handy if you need to update an email app on several devices.
   • For security purposes, the secure mail key only displays until you select OK. 
   • If you lose or forget the secure mail key, you can create new secure mail keys.
8. Select OK.
9. Go to your preferred email app and replace the existing password with your secure mail key. For an IMAP account, delete the existing password for both the IMAP and SMTP servers and replace them with your secure mail key.

We look forward to hearing if this helps!

When I try to login via browser or create the account in a mobile outlook app, it tells me the username and password maybe be wrong. I am receiving email with the same password on a different mobile outlook device with the same credentials. 

If you are using OUTLOOK, and are not using a Secure Mail Key in place of the actual password, you will have an error.

If you are using a Secure Mail Key, check your server names, etc.  I have noticed that some e-mail servers are currently misconfigured and are returning the wrong certificate, meaning that you have to use some obsolete names to actually get it to work.

Mobile outlook not desktop version. Also browser login. Desktop version never stopped working. 

It is NOT for desktop application of outlook. This is for MOBILE outlook and 6hat doesn't require keys. Also can't login in from any browser. No offense but not sure you are actually reading what the issue is......

Mobile Outlook, desktop outlook, it doesn't matter.  If you want to connect to an account, you have to log in.  To log in, you provide a userid and password.  but instead of a password, you provide the Secure Mail Key.

I did read what you wrote.  And I answered correctly.

Hi, @kjr53484!

Just as @JefferMC mentioned, the device you are accessing it on does not matter. Give the secure mail key a try and let us know if it helps.

We look forward to speaking with you!
