Impact on SharePoint if we change UPN name of users.
Hi all , I wanted to check what is an impact on SharePoint 2019 on-prem if we change the UPN of the users. I have OneDrive and SharePoint On-Prem. Please suggest.
The users interal guid will be the same so shouldn't create any major issues, Some issues such as profile images and such can occur until indexing kicks off.
