The Office 365 application follows the end of life (EOL) policy described below.
There are two types of application version:
- Major versions. These have two-part version numbers (19.2, 19.3, 20.1, and so on).
- Minor versions. These have three-part version numbers (19.2.1, 19.2.2, 19.2.3, and so on).
A major version is supported for 12 months from the date it is released, or for 6 months after the next major version is released. Depending on the release date of the next major version, the support period of the previous major version can be extended, but not shortened.
For example:
- 19.2 is released on 15 July 2019. In this case, the EOL date of 19.2 is 15 July 2020.
-
19.3 (or 20.1) is released on 15 August 2019. In this case, the EOL date of 19.2, 15 July 2020, does not change.
- OR -
19.3 (or 20.1) is released on 20 February 2020. In this case, the EOL date of 19.2 changes from 15 July 2020 to 20 August 2020.
The very first minor version replaces its major version and inherits its EOL date from the major version. In turn, the major version reaches its EOL date in a month after the release of the very first minor version.
The next minor version replaces the previous minor version and inherits its EOL date from the previous minor version. In turn, the previous minor version reaches its EOL date in a month after the release of the next minor version.
For example:
- 19.2 is released on 15 July 2019. In this case, the EOL date of 19.2 is 15 July 2020.
- 19.2.1 is released on 15 August 2019. In this case, 19.2.1 inherits the EOL date of 19.2, 15 July 2020, and the EOL date of 19.2 changes from 15 July 2020 to 15 September 2019.
- 19.2.2 is released on 19 February 2020. In this case, 19.2.2 inherits the EOL date of 19.2.1, 15 July 2020, and the EOL date of 19.2.1 changes from 15 July 2020 to 20 March 2020.
- 19.3 (or 20.1) is released on 20 February 2020. In this case, the EOL date of 19.2.2 changes from 15 July 2020 to 20 August 2020.
