Problems uploading PST file to office 365 RRS feed

  • Question

  • Hello guys,

    I have a problem when I want to import PST files into office 365 account.

    To be short, after I have uploaded the PST file via Microsoft Azure Storage Explorer, I created the mapping file, the file was validated and the task to import the PST started, but after the check of the PST file I get the next message: mailbox xxx@xxxx.com matches multiple entries, please use MailboxGUID. I have to mention that our office 365 accounts are synced with our on-promises AD.

    I have already checked the AD and i don't have any duplicates. 

    The question is, how can i use the MailboxGUID attribute?

    Thanks!

  • Hi,

    In Exchange Online for Office 365, please go to the Exchange Admin Center to check the user mailbox, confirm if the email address  xxx@xxxx.com matches multiple entries. 

    You can connect the PowerShell to Exchange Online, then run Get-Mailbox to retrieve the MailboxGUID. For example:

    The object Guid information is the MailboxGUID that you are looking for.

  • Additionally, this forum focuses on the general discussion for Office 365 ProPlus which is the Office applications included in Office 365 Plans.

    If you have any further question about the mailbox in Exchange Online (Office 365), it is better to ask a question in Exchange Online forum for more help:

  • You can upload PST file data to Office365 with the help of network upload method. But if you are a non-technical person, I would like to suggest a third-party tool, such as Bitacube Export PST to Office 365 Tool. By the help of this tool, any user can migrate PST file to Office365 fast and secure without any complicated method.
