Can a terminated user's email ID be allocated to new resource ?

[Gopi22]

Hi, 

We have a requirement in our project, where an old email ID (of a terminated user) to be allocated to a new user onboarded. 

For example, we had a user with name - Jack Jameson with email id 'Jack.Jameson@company.com'. This user has been terminated 2 years back. 
Now, we have a new user onboarded to the company with same name - Jack Jameson. Since the email address 'Jack.Jameson@company.com' is removed from our employee source of truth, which is Azure AD, same email address was allocated to the new user in Azure AD. However, in ServiceNow, the old email address was not removed from the deactivated user profile and hence due to unique constraint issue, it restricted the allocation of same email address to new user profile. 

I want to understand, what are the challenges, if we re-use the same email address in ServiceNow? 

Thanks,

Gopi

Hi @Gopi22 

Not a recommended approach, with same email id , employees also get confused.

Hi AG,

I do agree to your point, that is how I have suggested to the process analysts as well. But I am in need of solid points as to show, what would be the impact if we use the same email ID. Do let me know if you have any pointers, articles, which can help me with this.

Thanks,
