Every mailbox in Office 365 must be linked to an active Office 365 subscription in order for it to be used to send and receive email. When we setup your mailboxes - the first thing that we do is create a subscription for the correct number of mailboxes that your organization requires, when this step is complete a credit card must be entered in order to pay for the subscription. From time to time it may be necessary to update the details of your credit card if your card expires or is lost or stolen.
Since this procedure does need to be done from time to time, we have created a step by step guide to walk you through the simple process of changing your credit card details. Please note that you must be designated as an administrator for your organization in order to update the credit card details. If you don't see the admin tab when you login to Office 365, please let us know so that we can make the necessary adjustments to your account if you are the designated person that will be making the credit card updates.
Information required to complete this process:
1) Your email address
2) The password for your Office 365 account
3) The new credit card details
