This is a consistent behavior. Some of my invited users do not get the invite email.
When that happens, I deleted them from the invited list and re-invite them.
This way they do get an email.
Yes, and the computer they are using is plugged in to electricity too 
As I mentioned, re-inviting them sends an email, and no, it does not go into spam.
Hi @Doron_Neumann,
Sorry to hear that you’re facing this strange issue. Let’s dig into it!
Could you please share the email addresses of the users that did not receive their invitation email?
(If sharing it here is a problem, you can share them in private on a discussion that I will open in parallel)
Thanks.
