Microsoft has reminded business customers using older versions of Outlook that they have only two months to upgrade before their access to the company’s Microsoft 365 and Office 365 services is cut off. “After November 1, 2021, only Outlook 2013 Service Pack 1 (with the latest fixes) and later will be able to connect to Microsoft 365 services“, says the company in its blog corporate.
Last year, Microsoft stopped supporting older versions of Office that connected to its services online, such as Exchange Online, as of October 13, 2020. Affected Office editions included Office 2007, which was no longer supported; Office 2010, which was going to stop receiving support on the same date of October 13; and Office 2013, which was to receive support until April 2023. The closure of support in services had been brewing since 2017.
At the time, Microsoft had been surprisingly nice, saying that while support would officially end, that didn’t necessarily mean the end of connectivity. “We will not take any active steps to block other versions of the Office client, such as Office 2013, from connecting to Office 365 services, but these older customers may encounter performance or reliability issues over time,” the said then. developer.
That is what changes now. The November 1 deadline actually delinks older Outlook clients from Microsoft services. Microsoft explained that older Outlook 2007 and Outlook 2010 clients will be incompatible with two upcoming changes to services, which includes end of support for basic authentication (essentially the long-standing standard username and password combination) which was postponed in February 2021. However, Microsoft hasn’t said when it will stop supporting basic authentication.
For those who have yet to do without old Outlook clients, Microsoft recommended that they switch to the Office 365 or Microsoft 365 subscription model, which provides always up-to-date client software.
