After you configure Outlook 2013 or other devices by using an Outlook.com account, you receive the following error message:
There are too many devices syncing with this account. To sync using Outlook, try removing another device that is connected with this account such as a phone or another computer.
You may also receive similar error messages on other devices, such as your smartphone, tablet, or other computers that use Outlook 2013. Microsoft has confirmed this to be a problem between Outlook.com and Microsoft Outlook 2013.
If you subscribe to Microsoft Office 365, a fix for this issue should have been downloaded to your computer automatically.
If you do not subscribe to Microsoft Office 365, this was fixed in the March 12, 2013 hotfix package for Outlook 2013. For more information about how to obtain the hotfix package, click the following article number to view the article in the Microsoft Knowledge Base:

This error may occur for valid reasons, such if you use lots of devices or use a very large number of folders. If you have the fix installed but still experience this problem, complete a form on the following Microsoft website to have Microsoft reset the device sync limit on your Microsoft account:
You will be contacted within 24 hours and will be notified when your account has been reset. This lets you continue to use Outlook 2013 with EAS. However, you might encounter the same problem again if you use many devices or a very large number of folders (typically more than 1,500). For information about Exchange Active Sync (EAS) see the "More Information" section.
If you cannot install the hotfix package for some reason, and you still want to use Outlook 2013 with your existing Microsoft account, you can configure Outlook to use the POP3 protocol instead of the EAS protocol.Important
By using this older protocol, your calendar and contacts will not sync at all and you will have to manually check for new mail.Configuring your Microsoft account to use different settings
First, remove your existing email account that uses EAS with your Microsoft account:

By default, Outlook 2013 uses a protocol that's named Exchange Active Sync (EAS) to connect to Outlook.com accounts. If you receive the error message that's mentioned in the "Symptoms" section, you may receive similar error messages when you try to access your email account from other devices, such as other computers or mobile phones. This is why you must request a device reset by using the hyperlink in the "Resolution" section. As soon as the device sync settings are reset in your Microsoft account, you can regain access to your accounts on those other devices.
