Skype: The Address You Typed Is Not Valid

Skype: The Address You Typed Is Not Valid

Posted on December 9, 2020 by Madalina Dinita Leave a Comment

If you’re trying to sign in to Skype for Business, but you’re getting an error that says the address is not valid, this guide is for you.

Fix Invalid Address Errors When Signing in to Skype

Update Skype and Windows

Make sure you’re running the latest Skype version on your machine. Click on Notifications to check if you received any alerts about a new version.

Check if there are any updates available for the Windows 10 OS as well. Go to Settings → Update & Security → Windows Update → Check for Updates.

Add the DNS Records

This error could indicate the DNS records of the domain are no there. This prevents Skype from contacting the servers. If you are not an admin, ask the IT admin to add the necessary DNS records.

Keep in mind that it may take anywhere between 24 to 72 hours for the changes to take full effect. This means you may need to wait up to three days to be able to sign in again.

On the other hand, if you’re an admin, you can check out Microsoft’s Support page.

Rollback Office Updates

If you started getting this error after installing the latest Office updates, disable Office updates and then roll back to a previous version.

  1. To uninstall Windows updates, open the Control Panel.
  2. Then go to Programs and Features.
  3. Click on View installed updates in the left-hand pane.view installed updates control panel
  4. Select and uninstall the latest Office updates.

Repair Office

  1. To repair your Office files, relaunch Control Panel.
  2. Go to Programs and Features.
  3. Select Office 365/ Microsoft 365.
  4. Click on the Change button.
  5. Select Quick Repair. If that did not work, repeat steps 1 to 4 and select Online Repair.

  10. Launch Command Prompt as admin and run the run ipconfig /flushdns command. Then try to login again.

Run Disk Cleanup

Speaking of clearing the cache, you may also want to run a Disk Cleanup scan. This will help you to remove temporary files that might be interfering with Skype.

  1. Go to the Windows Search bar and type ‘disk cleanup.’
  2. Launch the Disk Cleanup app.
  3. Select the drive where you installed the OS and Skype.
  4. Select the files you want to delete.
