You generally cannot download the Microsoft Outlook 16.0 Object Library as a standalone DLL or library file. This library is part of the Outlook installation itself and is typically provided by a file named MSOUTL.OLB.
If you are looking for this file for a VBA project or software development, here are the legitimate ways to get it and use it. 1. Locate the file on your system
If you already have Outlook 2016, Outlook 2019, or Microsoft 365 installed, the file is already on your computer. You can find it at one of these common paths:
64-bit Office: C:\Program Files\Microsoft Office\root\Office16\MSOUTL.OLB
32-bit Office: C:\Program Files (x86)\Microsoft Office\root\Office16\MSOUTL.OLB 2. Add the reference in VBA
Instead of downloading a file, you just need to "point" your project to the one already there: Open the VBA Editor (press Alt + F11 in any Office app). Go to Tools > References.
Scroll down to find Microsoft Outlook 16.0 Object Library and check the box.
If it’s missing from the list, click Browse... and navigate to the paths listed in Step 1. 3. Alternative: Use "Late Binding" (No DLL needed)
If you're worried about your code breaking on other people's computers because they have different versions of Outlook, you can use Late Binding. This method doesn't require the library to be checked in the References menu at all. Example Late Binding Code: Add object libraries to your Visual Basic project
