Office 365 2013 End of Life – What you need to know.

Starting in February 2016 Office 365 2013 ProPlus and Business users will be upgraded automatically to Office 2016. In fact, many Office 365 Business plan subscribers are already finding themselves upgraded to Office 2016, without the option of rolling back to 2103 from the Office 365 portal. This is having major consequences as many Oultook and Office plugins don’t work correctly with 2016 yet. Exacerbating the situation further is the fact that Outlook 2016 doesn’t work with Exchange 2007.

What you need to know about Office 365 2013 End of Life…

1. The Office 365 portal will only give you the option of installing Office 2016 after February 2016, if not already.
2. Office 365 2013 (Pro and Business) will only be supported and updated through September 2016.
3. If you are not ready to automatically update to Office 2016 you need to take action to disable automatic office updates in Windows via Group Policy or registry edits.
4. If you are running Exchange 2007 you need to start planning an upgrade path since Outlook 2016 is not compatible.

Compliance Concerns

For those organizations that need to meet strict compliance requirements, such as HIPPA, PCI, SOX, or Dodd-Frank, you will need to plan on being upgraded to Office 365 2016 prior to September 2016 or you will risk being out of compliance since you will no longer receive important application updates from Microsoft for Office 2013.
