New minimum Outlook for Windows version requirements for Microsoft 365

Paul_Bergeron If you prefer to use the Office suite (that comes with Outlook and other applications, like Word, Excel & PowerPoint) that you can buy at a one-time cost and don't want to pay monthly or annual subscription cost for Microsoft 365, then you may opt to buy the following Office suite. The version is 2021, which is latest, so you'll be all set until Oct. 2026 (next 4 years, see: Office 2021 - Microsoft Lifecycle | Microsoft Docs) 

Buy Office Home & Business 2021 (PC or Mac) - Download & Pricing | Microsoft Store ($249.99)

yury06 I'd recommend the same to you, see my comments above for Paul.

tct_octque Outlook 2013 is supported until Apr 11, 2023 (connectivity to Outlook.com mailboxes after that date, is not guaranteed, and will probably be impacted), not Sep 2023 as you'd prefer it to be. So please keep that in mind. And please make sure you have installed all available updates for Outlook 2013 to avoid any connectivity issues until Apr 2023.

Blootplazma Yes, that's correct, as Oct 2023 is when mainstream support expires for Outlook 2019, see: Outlook 2019 - Microsoft Lifecycle | Microsoft Docs
