Looking for Active Directory attribute to store personal e-mail and/or personal mailing address

I'm trying to avoid updating the 2012 R2 schema (2008 R2 functional level) by adding a custom attribute like "otherAddresses".
I can't use the Exchange Custom Attributes because disabling a mailbox of a user would wipe those out of an active user.
My fear of adding a custom attribute is no test environment to do it in, no rollback plan/experience of recovering a Forest, and that adding a new attribute means all the DC's will re-sync every attribute in the Forest, causing network load and CPU issues.

So I'm considering what attributes exist that can store a personal e-mail address (like a gmail or yahoo address), as well as having the ability to store other information like a mailing address (123 Abc St, City, ST zip).

I came across the "unstructuredAddress" attribute. I'm not sure what this is for or what class it's typically associated with. Googling says it's for a router IP? Is that just an example? Could it be used for what I'm looking to store in there?

Any other suggestions for typically uncommon attributes for user/person class in AD that can be utilized for my need?

just use extensionAttribute1

My understanding is if the user has a mailbox, and it's disabled while leaving their AD account enabled, then "extensionAttribute1" data is lost.
My understanding is that is due to these attributes being part of the Exchange schema extensions.

A good place is using the Notes Attribute which is listed under the Telephone Tab. When you run the powershell cmdlet get-aduser -identity user1 -properties * | fl you will see this attribute as Info. This would be a good AD Attribute that you could use.

I can't say for sure garryshape, but I don't think it clears that attribute. I can test it tomorrow.

Sorry did not see this initally.

Yes you are correct. When you disable or remove a mailbox the Exchange attributes will be removed from the AD account. In this case it is true. Extensionattributes are values from CustomeAttributes in Exchange so they WILL be removed.

Ok well I created the attribute and fortunately I think it worked. No forest recovery needed it seems.

I did create the multi-value custom attribute though with the unique object ID I generated with the MS script, and it took. I don't see any signs of high CPU or bandwidth usage. I have connected to both domains in my forest and am showing the new attribute showing up in Attribute Editor.
Honestly I wish I had more control over the politics of this request but I don't.
