Sorry @danzu, I spoke to soon.
I can reference my inbox with [Inbox] (outlook://inbox), but to reference a specific e-mail, I have to reference it like this [e-mail] (outlook:xxxxxxxxxxx) without the //. This way, the link stops working…
If execute it both ways on windows run, it works, so it has to be the way that logseq treats the reference.
I’m I using it wrong in logseq? Is there another way to do this outlook:xxxxxxxxxxx?
