Setting email aliases in an Office 365 AD-synchronized environment

article #992, updated 1022 days ago

At least initially, one must:

  1. Load up adsiedit.msc,
  2. Find a user object,
  3. Get its properties,
  4. Click on anything in the list,
  5. Press P on the keyboard,
  6. Scroll to proxyAddresses and edit it,
  7. Set the primary address as (note the caps in the prefix),
  8. Set all alias(es) as (note the lowercase prefix!).

In some environments, a new tab appears in ADUC which means you don’t have to go back to ADSI Edit, but this is not always the case.
