Teams not sending OTP
Hi When adding a external user. Instead of sending OTP it sends the default invitation. I have the preview for OTP set to yes. am I missing anything? Thanks Frank
Frank1959 I haven't used this myself, but according to the https://docs.microsoft.com/en-us/azure/active-directory/b2b/one-time-passcode#when-does-a-guest-user-get-a-one-time-passcode:
When a guest user redeems an invitation or uses a link to a resource that has been shared with them, they’ll receive a one-time passcode if:
- They do not have an Azure AD account
- They do not have a Microsoft account
- The inviting tenant did not set up Google federation for @gmail.com and @googlemail.com users
At the time of invitation, there's no indication that the user you're inviting will use one-time passcode authentication. But when the guest user signs in, one-time passcode authentication will be the fallback method if no other authentication methods can be used.
