thank you for following up on this Noortje, still interested as my company is operating under MS environment.

Hi Pascal,

We have investigated your request, but Microsoft currently doesn't allow this possibility.

We will monitor any new development on this!

Perhaps consider Todoist. I switched from MS ToDo and am very content. Mainly the 2 way sync

Dear all, I would very much appreciate two-way sync to ensure that whatever is updated on Microsoft To-Do flows back into Mailbutler (so far it is one way from Mailbutler to MS To-Do). Thx, Pascal
