Situation: Sometimes when adding a new team member, they are unable to receive the invitation email with the link they need to click. Until a team member clicks that link, they can not join your team.
Solution: In the team administration section, the team Owner or team Admins can highlight the team member they have invited, go to the right of their name to the 3 dot menu, click that and select: Show Invitation.
That will allow you to copy the invitation link and information in order to send through another method such as company chat or another email address.
Here is a video walk-through for accessing that option: htps://share.getcloudapp.com/Apurng8z
