Why isn't my account syncing with Outlook 2016 on Windows?

At the moment, only personal Microsoft accounts using an Outlook.com domain are able to sync between Microsoft To Do and Outlook 2016. If your personal Microsoft account uses a domain such as @outlook.com, @hotmail.com, @live.com or @msn.com, then your to-dos should sync automatically between Microsoft To Do and Outlook 2016 on Windows. 

However, if you’re using a personal Microsoft account registered to a different domain, like @gmail.com or @yahoo.com, your to-dos won’t sync automatically. In order to sync your to-dos between Microsoft To Do and Outlook 2016, you’ll need to a create a new alias for your account by registering a new outlook.com email address.  To create a new alias, just do the following:

  • Head to https://account.live.com/names/Manage and log in to your personal Microsoft account.

  • Under Account alias(es), select Add email.

  • Make sure the option to Create a new email address and add it as an alias is selected and enter a new @outlook.com address.

  • Select Add alias.

  • Once the new alias has been added to your account, just select the option to Make primary.

Now that your new @outlook.com address is the primary alias for your account, you’ll need to update your Microsoft account within Outlook 2016:

  • First, remove your initial Microsoft account.

  • Then add your new @outlook.com email address as an Microsoft 365 account to Outlook 2016 by heading to File>Add Account.

  • Enter your new @outlook.com email address and then select Connect.

  • Alternatively, you may need to enter your name, email address and password and then select Next.

  • If prompted, enter your password and then select OK.

  • Then just select Finish.

Your to-dos should then sync between Microsoft To Do and Outlook 2016 automatically.
