[German]A short reminder for administrators and users who use Microsoft Office. Support for various Office services in older Office versions will end in October 2020. And for macOS, support for Microsoft Office 2016 will end.
Office: Change in connections to Office 365 services
In October 2020, Microsoft will discontinue support for connections to Office 365 services for older versions of Office. Microsoft has published this support document. After October 13, 2020, only the following versions of Office will be supported:
- Microsoft 365 Apps for Enterprise (formerly Office 365 ProPlus)
- Microsoft 365 Apps for Business (formerly Office 365 Business)
- Office 2019, like Office Professional Plus 2019
- Office 2016, like Office Standard 2016
This means in return that older Office versions are no longer supported with regard to connection problems. This has a particular impact on access from Microsoft Office to Office 365 services such as Exchange Online, SharePoint Online and OneDrive for Business. However, Microsoft writes explicitly:
We won’t take any active measures to block other versions of the Office client, such as Office 2013, from connecting to Office 365 services, but these older clients may encounter performance or reliability issues over time.
You will not actively lock older versions of Office. But if there are sudden problems with time – or after an update – affected users and administrators will not get support anymore. Microsoft expresses it like this: After October 13, 2020, older Office customers will no longer be considered in the ongoing investments in our cloud services.
TLS 1.0/1.1 support switched off
It should also be noted that Microsoft TLS 1.0/1.1 will be switched off from 15 October 2020. I had pointed this out in July 2020 in the article Office 365: TLS 1.0/1.1 support ends on Oct. 15, 2020. To connect to Office 365 services, at least TLS 1.2 must be supported. See TLS 1.0 and 1.1 deprecation for Office 365 and Preparing for TLS 1.2 in Office 365 and Office 365 GCC for more information.
Exchange Online Basic authentication
Microsoft also plans to turn off basic authentication for Exchange Online. The support article still mentions April 2020 as the date, but this is wrong. In view of the coronavirus pandemic, Microsoft has postponed the date, as I mentioned in the article Disabling Exchange Online Basic Authentication in 2021.
macOS: Support for Microsoft Office 2016 ends
Information for Mac user with Microsoft Office 2016. German news site heise mentions within this article, that support for this version of Office will expire in October 2020. Then there will be no more updates for users of older macOS versions.
