Voicemails marked as EXTERNAL MESSAGES - Prevent Phishing but how?

[kai_osthoff]

Hi.

If we our any of our customers activate Voicemail within Teams, they get the following email:

Normal not technical well trained users will not open any attachements, because outlook says, that this email came from outside the organization.

Uff.

Only workaround is to use only the Teams client itself.

Okay. It seems a nice workaround, but not for any customer.

Any idea how i can disable the "outside organization"-Information ONLY for that VOICEMAIL from teams?

Kai.
