Hi!
Welcome to Microsoft Q&A forum.
Technically speaking you can install it however, expect the following issues.
- Downside
- No security updates
- No compatibility updates
- Microsoft will not fix bugs
- Not guaranteed to work with Windows 10 or 11
- Outlook 2013 has major problems connecting to Microsoft 365, Gmail, Yahoo, etc.
-
- Outlook 2013
- ay fail to connect to Outlook.com, Hotmail, Gmail, Office 365
- May not sync modern authentication (OAuth)
- Word/Excel 2013
- Might crash with Windows 11 updates
- No fixes for security vulnerabilities
- Activation issues
- Error 0x8004FC12 or 0xC004F200
If you are using it just for Word/Excel OFFLINE, It will usually run fine.
Do you have a specific reason why you like the older Office 2013?
