I'm trying to update my email address on my Unity account, but I'm encountering an error that says 'You have too many emails. The maximum is 5.'

Symptoms:

• I need to update my Unity account email address but cannot due to an error.

Cause:

There is a limit on the amount of email addresses that can be linked to a Unity account at any one time. Any email addresses that have been associated with your Unity account are linked to it permanently.

If this limit has been reached when trying to add another new email address, an error will appear preventing the update.

Resolution:

Any previous account email addresses must be removed before the new email address can be added.

Previous email addresses cannot be removed via the Unity ID portal. In order to have your old email addresses removed, you must contact the Customer Experience Team to make the update.

How do I change the email address attached to my Unity account?

I am unable to confirm my email address/reset my password.

I see the error, 'We have encountered an issue during this login attempt. Please contact Unity Support(support@unity3d.com)'.
