Have run Exchange2003MBtoMEU.vbs on user now unable to reconnect mailbox RRS feed

  • Question

  • Hi, I have been moving from Exchange 2003 to Office 365 and using the Exchange2003MBtoMEU.vbs script to convert each user to a mail enabled user.

    I have run into a problem where I need to access a disconnected user's mailbox but am having no luck.

    Attempting to reconnect the user mailbox to the original user account results in the error: This recipient already has an e-mail address. ID no: c1034a07

    Attempting to create a new user without a mailbox and reconnecting the disconnected mailbox to the new user results in this error: The operation cannot be performed because this mailbox was already reconnected to an existing user. ID no: c1034ad6

    Is there any way that I can get access to this mailbox even if just to export the content to a .pst file?

    Thanks in Advance
