Time marches on. Exchange 2013 and Outlook 2013 have now exited out of mainstream support and will be serviced as per their extended support life cycle policy.
Several years Ready For The Next Episode? and The New Exchange were the first posts here on Exchange 2013. The latter has an image of how the Exchange team blog used to look. That was back when orange must have been the marketing colour of choice!
The below images and links will take you to the relevant pages on the product support lifecycle for Exchange 2013 and Outlook 2013.
Exchange 2013
Office 2013
Note that for Office 2013 the information for Service Pack 1 is shown. This is because the RTM version is already unsupported.
Also, this is for the MSI version of Office 2013. The Office 365 Pro Plus 2013 client is already unsupported. Support for that product ended in February 2017.
Cheers,
