Office 365 group Aliases

[prashantguptag]

Hi,

Can somebody please explain me why do I see two SPO aliases for some Office 365 groups and for rest other groups i see only one SPO alias. Attached is the screen shot for you reference

Have you perhaps renamed any of the groups or group sites?

Ok did some digging around it and based on given example what i did is, I retrieved the site urls based on the guids available in group aliases for SPO. I got two different sites but when I used Graph API to get the associated site for the group I am getting only one site which is one of the site retrieved earlier. So how should i understand this? I am confused. Should I totally ignore the site and consider it orphan which is not returned by Graph API?
