"user@email address" is already in use by "other user" RRS feed

  • Question

  • I disabled the "other user" account and I still can't use an address I want for the first user. I copied this other users profile to create the first user and now can't change first users email address or find other users mailbox to change properties there. Thanks for any help proffered.

    Did disable the AD account or mailbox? Disabling the AD account doesn't remove the SMTP address from it.

  • Hi Vegasnext,

    Agree with Andy, I also recommend you refer to the following article to understand the relationship between AD account and mailbox.

    https://technet.microsoft.com/en-us/library/bb232039(v=exchg.150).aspx

    Base on your situation, there are two ways to solve:

    1. Delete "other user" AD account and reconnect the mailbox to the "first user"

    2. Create a new email address for "first user"

    Best regards,

  • Use the MFCMAPI, login to any account. Click on the address book, open the "View AB Hierarchy". From there open the global address list. Click on the desired user. Double Click on the "PR_EMS_AB_PROXY_ADDRESSES". Change the value you want. This should work.
