Microsoft is making its customers on Outlook 2007 and Office 2007 to upgrade as each of the products will no longer have the extended support as of Tuesday.
That means it will no longer have any security updates, support or technical notes.
Microsoft wants its Office 2007 customers to switch over to Office 365 in the cloud or to upgrade to Office 2016.
Office 2007 introduced Microsoft’s “ribbon” interface that brought a series of tabbed toolbars with each ribbon containing related buttons.
For those who have already use Office 365 that still use Outlook 2007, it will be important to upgrade by the end of this month, after which the product won’t let users access Exchange Online mailboxes though the Office 365 portal.
“Customers who use Office 365 will have noted that there is a change to the supported client connectivity methods. Outlook Anywhere is being replaced with MAPI/HTTP. Outlook 2007 does not support MAPI/HTTP, and as such will be unable to connect,” Microsoft highlights in a send-off note for the email client.
Microsoft is not offering enterprise customers extended support for Office 2007 through its custom support contracts. The same goes for its other Office products, including Exchange Server; Office Suites; SharePoint Server; Office Communications Server; Lync Server; Skype for Business Server; Project Server and Visio.
Microsoft said demand for custom support has diminished with greater adoption of Office 365.
