Link to doc routes to meeting UI

[Gp6450]

I have shared a link to a document hosted on Teams with an external user. When they click the link they are brought to the meeting interface as if they were on a call and are shown the message, "when the meeting starts we will let people know you are waiting". Is the issue with the link that I'm sending which does work for internal users or am I bumping into an IT issue at their end in which all Teams meeting links are treated as meetings?

To share a document you'll currently need to Open in SharePoint and use the Share button there.

@Steven Collier Thanks for the input, curious to know why the link into the Teams site would cause the issue I reported.

I can't explain that, when I do the same from the other user I get an error saying I don't exist in AD in that tenant, which is what I would expect.
