Free add-in solution: multiple calendars in the Todo pane

've seen several threads here over the years asking about showing multiple calendars in the Todo bar, all concluding it isn't possible natively. I had the same problem and ended up building a free VSTO add-in that solves it.


It creates a custom pane in Classic Outlook showing appointments from all calendars across all accounts (colour-coded), plus tasks and flagged emails in the same view. Items can be opened by double-clicking, and there's a + button for new tasks.


It requires Visual Studio Community (free) to build and install — the README walks through the whole process.


GitHub: GitHub - galexmay/Outlook-Todo-Plus-Multiple-Calendar-Pane: A custom outlook pane to replace the standard todo/calendar pane. This includes all calendars.


Hope it's useful to others who've hit the same wall.

Thanks for sharing the GitHub repo—I'm sure plenty of power users running Outlook 365 will jump on this right away!

That is a fantastic contribution to the community! Outlook's native To-Do bar limit of only showing the primary calendar has been a pain point for multi-account users for years, so building an open-source VSTO add-in to merge multiple calendars with tasks is a brilliant workaround.

Did you really spend a month asking and answering questions, building up a reputation, just so you could slip some Spam links into expanded Reply Quotes?

This thread:

What is the best way of using the Classic Outlook client to change my email address?

If so, I do admire your persistence and subtlety.

This is a really useful workaround for something Outlook should probably have supported natively years ago.

Having multiple calendars, tasks and flagged mail all in one pane sounds much more practical than constantly switching views. Nice of you to put the whole thing on GitHub too.

The Visual Studio build step may scare off some less technical users, but with a decent README this could be a great solution for anyone who still relies heavily on Classic Outlook.
