I have an issue with our Azure AD tenant syncing with my domain AD account. When we set up the tenant (along with Office 365), we used a generic ID in the format firstname.lastname@example.org. My existing domain account is in the format email@example.com. This "role conflict error" shows up in Azure AD.
I should also add that I am having issues granting admin access to my on-prem account (despite it being able to log into any Office 365 services as Owner). For example, I cannot access any Sharepoint sites with the on-prem account unless I request access from any other synced account that has Owner privileges.
At this point, I would simply like to delete the onmicrosoft.com account from Azure, and merge the two accounts. However, I cannot delete that account, and I clearly do not want to delete the domain account, as it has needed functionality in our on-prem domain. What is the best way for me to remove this sync error, and fix this issue?
