Technical Support is Ending Soon for Some Versions of Microsoft Office
The obvious action item related to this issue is to make plans now to upgrade to a newer version of Office, including one provided through an Office 365 or Microsoft 365 subscription. Under the subscription models, you can avoid substantial cash outlays to upgrade licenses throughout your organization. Additionally, subscription models help you to avoid the risk of obsolescence and lack of technical support. In addition to considering an Office 365 or Microsoft 365 subscription, you may also want to take a look at Zoho One and G Suite. Both these offerings compete with the Office franchise available from Microsoft. Further, they offer some unique characteristics and options that might make them a more attractive option in some cases.
Only Supported Versions of Microsoft Office Will be Supported When Connecting to Office 365 Services
Does This Change Mean You Won't be Able to Access Your Email Using Older Versions of Outlook?
If your organization is running any Office client older than Office 2016, Microsoft will not take any active measures to block them from connecting to Office 365 services. However, legacy clients attempting to connect to a modern, always-up-to-date cloud service may experience performance and reliability issues. Customers will face an increased security risk, and may find themselves out of compliance depending on specific regional or industry requirements. Microsoft Help may not be able to resolve issues that arise due to unsupported service connections.
