Unable to handover project to My group admin

<span style=""">Dear Support,

I am leaving my current organization for which I intend to handover all the projects to itadmin@nepaldistilleries.com.np our group mail for further use.
However, I am not able to add even after entering the email address please share me a solution.

Dear customer,
May I ask if the itadmin@nepaldistilleries.com.np is a sub-account? Are the receiving account and the tenant in the same cloud service region?
