When are the support end dates for Microsoft Office LTSC 2021?

The end date for the mainstream support is on October the 13th 2026. This is for both supports: the updates and the security. This means that after this day, your license and applications will not be receiving any updates including security updates. It is important to note that these two update types are usually split up in time.

Should you upgrade to Office 2021 LTSC or migrate to Microsoft 365?

With Office 2021 LTSC you need to pay once at the moment of purchase. Microsoft 365, on the other hand, is a subscription for which you need to pay monthly or yearly.
