How to Fix ‘Sign In 0x87dd000f’ Error on Xbox

Several Xbox and Xbox One users are suddenly getting a Sign-in Error (0x87DD000F) when they try to log into their console, even though they are connected to an Internet network. Those encountering this problem report that they have an active Xbox Live membership. Although the issue is sometimes linked with a server issue on Microsoft’s side, that’s not always the case. Because of this roadblock, users are unable to play any online games or see their friend list.

What’s causing the Sign-in Error (0x87DD000F)?

We investigated this particular issue by looking into various user reports and the repair strategies that are most commonly reported as being effective in this particular scenario. As it turns out, numerous causes might lead to the apparition of this issue. Here’s a shortlist of culprits that can be responsible for this issue:

  • Xbox Live service is down – This is certainly one of the most common causes that will produce this error code, but it’s certainly not the only one. If you think a DDoS attack or a maintenance period might be responsible for the issue, you can check the status of the Xbox servers by going through the official channels.
  • Firmware glitch – A firmware glitch can also be responsible for this error code. A lot of users that have been dealing with the same problem have reported that they managed to resolve the issue entirely by performing a power cycle. This procedure will drain the power capacitors, which will end up resolving a lot of firmware-related issues.
  • Limited account privileges – You might also encounter this error code if you previously set this account as primary on a different console. If this scenario is applicable, you’ll only be able to circumvent the sign-in error by logging in while using Offline Mode.
  • Modem/router inconsistency – Another reason that might end up producing the error is an improper Alternate MAC address. In this case, you can fix the problem simply by accessing the network settings of your console and clearing the Alternate MAC address.

Verifying the status of the Xbox live services

If all services have a green checkmark, you can conclude that the problem is not caused by an Xbox Live service. In this event, it’s clear that there’s a problem with your local configuration – either your console or router/modem.

On the other hand, if your investigation revealed some wide-spread issues, certainly, the issue is not limited to your console. In this case, the repair strategies included below should be disregarded since they will not help you in resolving the issue. Instead, all you need to do is wait some time until the issue is resolved by Microsoft’s engineers. Be sure to check back regularly until the problem is taken care of.

In case you’ve determined that the issue is not caused by an Xbox Live server, move down to the next methods below to try out some repair strategies that were used to resolve the 0x87DD000F error code.

Method 2: Performing a power cycle

If you previously confirmed that you’re not dealing with a wide-spread issue, this procedure is the most effective way of resolving the 0x87DD000F error code. By performing a power cycle on their console, some users have reported that they were able to sign in with their account while avoiding the error message altogether once the next booting sequence was complete.

Don’t confuse this procedure with a regular restart. A power cycling will drain the power capacitors of your Xbox console, which will end up resolving a lot of firmware-related issues that are known to occur with both Xbox360 and Xbox One consoles.

Here’s a quick guide on performing a power cycle on your Xbox console:

  1. With your console turned on, press and hold the Xbox button (located on the front of your console). Keep it pressed for about 10 seconds, or until you see the front light flashing intermittently – Once you see this behavior, you can let go of the button.
  2. Once the shut down has been performed successfully, wait a full minute before turning back on. You can even try to disconnect the power cable from the power source to ensure that the process is complete.
  3. When you are ready to turn it back on, press the power button again, but don keep it pressed like before. Then, let the startup sequence complete and pay attention to see if you spot the animation logo. If you see it appearing, it’s confirmation that the power-cycling procedure was successful.

  4. Once your console is fully booted, try to complete the sign-up process once again and see if you’re still encountering the 0x87DD000F error code.

If the same error message is still appearing when you try to sign in with your account, move down to the next method below.

Method 3: Signing with your account using Offline Mode (Xbox One Only)

As it’s been reported by some affected users, you might be able to resolve this issue by changing your Network settings to Offline Mode and signing into your user account. A lot of users have reported that going this route allowed them to circumvent the 0x87DD000F error code entirely. After they disabled Offline mode and they were able to use online features and access their friend list without issues.

Here’s a quick guide on switching your console’s network mode to Offline Mode and doing the signing in this way:

  1. Press the Xbox button on your controller once to open up the guide menu. Next, use the newly appeared menu to navigate to Settings > System > Settings > Network.
  2. Once you’re inside the Network menu, go to Network settings and access the Go offline option.

If the same issue is still occurring or you weren’t able to complete the steps above, move down to the final method below.

Method 4: Clearing the Alternate MAC address

If this scenario is applicable, you will be able to fix the problem by going into the Network menu and clearing out the alternate MAC address.
