When you receive notification from Teams in outlook, please watch out the "Sender Name" . Some times sender name missing in the conversation, It’s not consistent and neither is replicable on demand.
Anyone facing the same issue?

We are facing this issue as well. Most teams notifications have the correct sender, but some mails don't, regardless of the person who tried to reach the recipient.
Are there any news on this?

We are working with Microsoft to fix this issue. Please share if you got any solution for this.

My case might be slightly different from yours, since outlook web shows the sender name correctly. Only mail clients are missing the "From" header completely. Subsequently the Sender Policy Framework soft-fails checking the wrong domain.

The "Sender" header is present, but the "From" header is not.
As comparison: a teams notification with sender name present:

It features "From" and "Return-Path" headers, and passes SPF. Instead, the "Sender" header is not present. (It also has a DKIM signature, which adds Authentication Results.)
