If you have previously archived an account you can always restore it to reactivate an account and gain access to the account data. Here is how to do this.
First, select the View Accounts tab.
Choose Archived for the type of account.
Choose all of the account(s) that you would like to restore by checking the box next to their name. You can sort the list by name, email address or last login. You can also select accounts across multiple pages.
Once you have all of the accounts selected, select the Unarchive button. This will restore all of the accounts.
