1. Check your credentials

According to users, if Office keeps asking for password, the problem might be credentials in the Credentials Manager.

Apparently, there was a Generic Credential with a Persistence set to Session. As a result, you were signed in to Outlook as long as you were logged on to Windows.

After logging off, you’ll be asked to sign in back to Office. This can be an annoying issue, however, there’s a way to fix it. To fix this problem, you just have to find the problematic credential and delete it.

Now you have to recreate the credential with the same settings, but this time be sure to set Persistence to Enterprise.

To access the Credentials Manager, do the following:

  1. Press Windows Key + S and enter control panel. Select Control Panel from the list of results.

  2. Once the Control Panel opens, head over to the Credential Manager.

4. Delete your account credentials, remove the email profile and recreate it

If Office keeps asking you to sign in, the problem might be your email profile. Many users reported this issue after upgrading to the new version of Office.

The upgrade caused the issue with their email profile, so they were forced to recreate it in order to solve the problem.

Before recreating your profile, users are suggesting to remove all Microsoft Office credentials, so you might want to do that. After doing that, you just need to remove your profile by doing the following:

  1. Open Outlook and go to File > Account Settings > Manage Profiles.
  2. Now you need to select Show Profiles.
  3. Select your profile and click the Remove button.

After doing that, you just need to create a new Outlook profile. This is fairly simple, and you can do it by following these steps:

  1. Open Outlook. Now go to File > Account Settings > Manage Profiles > Show Profiles > Add.
  2. Enter the desired profile name and click OK. Now follow the instructions on the screen to complete the account creation process.

Once you create a new account, check if the problem is still there. Many users reported that this method worked for them, so you might want to try it out.


5. Delete unnecessary shared calendars

Several users reported that Office kept asking them to sign in due to an old shared calendar. Apparently, the calendar was made as a SharePoint list, and it caused the log in issue to occur.

To fix the problem, users just had to remove the calendar and the problem was completely fixed. If you have any old shared calendars that you don’t use, delete them and the issue will be resolved.


6. Make sure that encryption is enabled

According to users, sometimes this issue can occur if the encryption feature isn’t enabled. In order to keep your emails safe from third-parties, it’s advised to use encryption.

Several users reported that by not using encryption they caused Office to keep asking for password on their PC.

This can be an annoying issue, but you can fix it by doing the following:

  1. Go to the Account settings in Outlook.
  2. Now go to Change settings > More Settings > Security tab.
  3. Locate Encrypt data between Microsoft Outlook and Microsoft Exchange option and enable it.

After enabling this feature, the problem should be completely resolved and everything should start working again.

7. Enter the password manually in Credentials Manager

All your passwords on your PC are saved in the Credentials Manager, but sometimes glitches with it can occur. This can cause issues with certain applications such as Microsoft Office and Outlook.

If Office keeps asking you to sign in, you might be able to fix the problem by doing the following:

  1. Open Credential Manager. We showed you how to do that in Solution 1, so check it out for detailed instructions.
  2. Once you open Credential Manager, enter the password manually in all locations where your email address is stored. Save changes and close Credential Manager.
  3. Press Windows Key + R and enter %localappdata%. Press Enter or click OK.
    Office 365 keeps asking for credentials, won't stay signed in, login keeps popping up
  4. Navigate to the MicrosoftOutlook directory. Locate Autodiscover.xml file. This file can also have an array of letters and numbers in front of its name, so don’t be confused by it. Move this file to a different location or rename it.
  5. After doing that, start Outlook and it should start without any prompts.

This solution might be a bit advanced, but users reported that it worked for them, so be sure to try it out.


8. Try changing the login format

If Office keeps asking for password, you might be able to solve this problem simply by changing the login format. A couple of users reported that they manage to solve the problem with the login screen simply by changing the login format.

Instead of their email address, they had to use the following format:

  • MicrosoftAccountyour_email@outlook.com

After changing their login format, the issue was completely resolved and everything started working again.


9. Make sure that you’re using an app password

Sometimes Office keeps asking to sign in because you’re not using an app password for Outlook. The App password is a great feature since it will generate a unique password that you’ll use just for Outlook.

As a result, if a hacker steals your Outlook password, it still won’t be able to access your account.

To generate an app password, do the following:

  1. Go to your Microsoft account page and head over to the Security basics section.
  2. Now choose More security options.
  3. Go to App passwords and click on Create a new app password.
  4. A password generator will now appear on your screen. Generate a password and use it instead of your regular password in Outlook.

After doing that, Outlook should start working again and you won’t have to deal with the login screen anymore.


10. Update Office to the latest version

According to users, Microsoft is aware of this issue, and it’s possible that this issue is already fixed. If Office keeps asking for password, you might be able to solve this problem simply by updating Office to the latest version.

This is incredibly simple to do, and you can do it by following these steps:

  1. Open any Office application.
  2. Go to File > Account > Update Options > Update Now.
  3. Office will download available updates and install them.

Once the updates are installed, check if the problem is still there.


If Office keeps asking you to sign in, the issue is usually related to your credentials, but we hope that you managed to fix it using one of our solutions.
