[Aman verma]

Hi, 

I am sharing one of the sites with external users, invitation is being sent accordingly, however when user accept the invitation he doesn't get to the site and get below error.

Also, i checked on Azure AD and found that external users aren't getting added as a guest users on AAD. 

Can you please help this asap

Thank you!

Hi @Aman verma,

Can you share a few screenshots of the entire experience (e.g. sharing the site, the e-mail that is received, etc.). This definitely looks unexpected but need a little more to help debug! Thanks!
