Connect existing AD user to existing Mailbox as principal user (where existing mailbox has a different user attached)

    问题

  • Hey Everyone,

    As the title suggests I'm attempting to connect an existing AD user to an existing Mailbox as the principal user(where existing mailbox has a different user attached) - This so that attached to the ad assigns the correct mailbox automatically. When I attempt to change the mailbox user to the AD user I get the error message that the name is already in use, and attempts to circumvent this have failed.

    Thank you in advance for any trouble to be taken.

  • I have two AD profiles (assigned to the same person): Profile A and Profile B.

    Profile A got corrupted when upgrading from w7 to w10 and profile B was created.

    I have One mailbox assigned to Profile A. 

    I need Profile B to be assigned to this mailbox as the principal user, however when I change the principal user to Profile B, it says profile B already exists (which is only logical). So far I failed to reassign Profile B as the principal user, I'd appreciate any and all help.

    A bit of elaboration: so far the problem was solved by just giving acces rights to profile B, however for the GDPR we set up a mdm system which synchronises through the AD, causing problems down the line (since Profile B is the active profile)

  • What's an AD profile?  Do you mean a Windows logon profile, or an Outlook profile, or something else?

  • When I try:

    Set-User -UserPrincipalName 'ProfileB@domein.local' -SamAccountName 'ProfileB' -Identity 'domein.local/<PLACEINAD>/ProfileA'

    I get the respone: "Error: ProfileB@domein.local is already used by other adressed object ProfileA, use a unique value"

    With AD profile I mean a user in our active Directory (used to login to both our domain as into our e-mails)

  • Is that the real message?  I'm asking because it has a misspelling.  It's always best if you copy and paste any messages exactly as they appear.

    It looks to me as if you have a duplicate entry.

    Use:

    Get-Recipient -Identity "profileb@domein.local"

    to see if there are any recipients using that address. 

    Use ADSI Edit to examine object profilea@domein.local to see if any of the following attributes have the values shown:

    proxyAddresses - smtp:profileb@domein.local

    targetAddress - smtp:profileb@domein.local

    userPrincipalName - profileb@domein.local

    mail - profileb@domein.lodal

    If it has, you have a duplicate.  Either assign a different address or remove the conflicting property from profilea@domein.local.
