On October 31st, Microsoft will be changing the way that Outlook connects to Exchange Online. If you are an Office 365 customer, you may be impacted by this change if you use Outlook 2007 or older. If so, OXEN is here to help you prepare.
Who will be affected? The change affects all Exchange Online customers. However, only customers using Outlook 2007 (or older) need to take action beforehand. If you have Outlook 2010 and it has not been updated in a long time, you may also experience issues.
What will be affected? Microsoft Outlook 2007 (and older) for Windows will no longer be able to connect to Exchange Online and receive email. This change will not impact Outlook on other platforms, such as Office for Mac and Outlook mobile.
(Note: Outlook 2007’s extended support ended October 10, 2017. This is why this change in Microsoft Outlook connectivity is not being back ported to Outlook 2007. We strongly encourage upgrading your Outlook 2007 due to its end of life and lack of support, whether or not you use Exchange Online/Office 365.)
Why is this change being made? This change is being made to increase the security of connections from Microsoft Outlook clients to Exchange Online services. It enables security features like two-factor authentication.
How can I prepare? If you use Microsoft Outlook 2007 (or older) you will have to upgrade to a newer version which is supported. If you are running Outlook 2010 that has not been updated in a long time, you will need to update it.
