I am currently migrating mailboxes from Exchange 2010 to Exchange 2013 on prem. I have installed PST Capture 2.0 and 64-bit Outlook 2013 on a Windows 2008 R2 machine and have installed the PST Capture 2.0 agent on a workstation that has some .pst files on it. PST Capture finds all the .pst files on the workstation, but when I use PST Capture to try to import PST files into a mailbox on Exchange 2013, I get the error "Import error: Error opening mailbox username@mycorp.com".
I created a userID with a mailbox to run PST Capture. Based on the instructions at
https://technet.microsoft.com/en-us/library/hh781035%28v=exchg.141%29.aspx I have made that user a member of the groups that are assigned the Public Folder Management role, the Mailbox Import Export role and the Organizational Management role. The
user is also a local admin on the machine running the PST Capture console. While the error sounds like a permissions issue, these are the only permissions I could find documented for PST Capture. I am starting PST Capture with "Run as administrator"
Any ideas why this isn't working? Are there any other permissions that the PST Capture user needs? Is there anything else I need to do?
Thank you very much for your help.
