Office 365: Synchronized/Migrated user showing wrong UPN in Office 365

Oh no! I forgot to change/set the user’s UPN correctly before migration! Even a simple job we could get it wrongly. Thus, this will lead you to panic. Well, if you are panic, just take a deep breath.

Usually, such problem we resolve it by breaking/disable the DirSync so that the user’s status change from “Sync from on prem” to “cloud”. So that if we could make the changes at the Office 365, without interrupting the on-prem. However, this kind of solution is troublesome because it takes hours for the DirSync to complete disable and waiting for the user’s status to change. When I mean by hours, depends of the amount of users you have at Office 365. The larger the amount the longer it takes for the time taken for the DirSync to complete disable and for the user’s status to change.

Here are the problems we faced:

  1. Forgot to set the email policy
  2. Forgot how to set email policy
  3. Set the wrong email policy
  4. Highly confident and doesn’t double check
  5. Doesn’t do enough research about preparation of migration

Lucky for me that I have found a way to solve this kind of clumsiness, please refer to the reference given below.

Note: This solution is only for clumsy situation. Don’t put it into your planing of migration, because this will make you feel like a total blockhead in front of your customers. Please do not take it in as a habit.
