Outlook keeps asking for login credentials

Hi Jennier,

Thank you for the reply. My reply to your queries:

1. Tried deleting password caches, does not work. 

2. Yes, can sign through web mail app. 

3. Dont think others are facing this issue. 

4. I will send the screenshot shortly. 

Thanks a ton again. 

Hi RJ.esquire,

Thanks for your information. You can provide the screenshot to us at your convenience.

Have you changed the password or turn on two-step verification for your affected account recently? If you are not clear about whether your account has been set up two-step verification, you can confirm it with your admin.

Since you mentioned you have two Exchange account configured in Outlook, may I know if they are in a same profile? If you set the affected account in a independent profile, please try to repair your Outlook Data File as following:

If they are in a same profile, please try to create a new profile for the affected account to check the outcome. (If you are using Office 365 for Business account, just configure it automatically with autodiscover)

Thanks,

Hi Iry, Jennier,

I have attached the screenshot for your reference. You will note that there are two exchange accounts configured in outlook. Regarding profile, may I request you to please explain that how can I check whether both the accounts are in the same profile. Thanks a ton for the help. Highly obliged.

Hi RJ.esquire,

If you have multiple profiles, when you open Outlook, you will get following option to choose profile (before it, please confirm that option "Prompt for a profile to be used" has been selected in control panel):

After you selected one and click OK, then you can see the accounts in this profile. So, from your screenshot, you set up two accounts in this profile. So, please try to create a new profile for the affected account as I mentioned, and then open Outlook with new profile.

Thanks,

Iry

Dear Iry,

Thank you for the explanation. I checked and note that there is only one profile. Attaching the screenshot for your reference. 

Hi RJ.esquire,

Yes, so, you configured the two accounts in a profile. Please try to create a new profile for the affected account as I mentioned in my previous reply to check the outcome. 

Note: Before creating the new profile, please clear your Windows credential as following first:

1. Type "Credential Manager” in the search box of your computer >> Click on “Credential Manager”.

2. Click “Windows Credentials” > “Generic Credentials”, you will most likely see the entries about your email account.

3. Delete them. 

After you created the new profile, please open Outlook with the new profile and check if the issue persists.

If the issue still occurs in the new created profile, please try to test email AutoConfiguration as following: 

1. Press Ctrl button and hold on, click the Outlook icon on the right-bottom corner.

2. Then click "Test Email AutoConfiguration..."

3. Input your email address and password, click Test.

Since it's unavailable to copy and paste Results, please take some screenshots for your Results. And for the XML, you can select all contents and use Ctrl + C to copy them, and then you can paste to a txt document. 

Please send the Results screenshots and XML txt file to us in Private Message.

Thanks,

Iry
