dinhngtu / OutlookCloseToMinimize

Minimizes Outlook when the Close button is clicked. For use with the "Hide when minimized" option.

Installation

You'll first need to install the VSTO runtime.

Remove all existing versions of OutlookCloseToMinimize. Then double-click OutlookCloseToMinimize.msi.

The addin works best when the "Hide when minimized" option is enabled (by right-clicking Outlook's tray icon):

If Outlook crashes

If Outlook crashes, simply run outlook.exe /safe and remove the addin manually from Options - Add-ins.

If Outlook disables the addin by itself

Apply the included Registry file: forceload.reg (right-click - Save link as...)

I tested the addin with Outlook 365 and .NET 4.7.2, but in theory it should work with older Outlook versions with no problem.
