Hi Alan,
the issue might be with the PST file you’re importing from, would you mind sending it to rust@emclient.com, so we can have a look at what the problem might be?
Please include a link to this forum topic so we can get back to you here.

Hi Olivia, I am afraid that I have solved my problem using another email client and essentially giving up on Outlook 2007. A bonus for me was that it has allowed a complete reassessment of my email usage, with the benefits outweighing the disadvantages. In addition, the PST file involved is very large and with much private data , so would be inappropriate to send to you. Having searched the web for PST file problems, I very much gained the impression that they are very likely impossible to solve in the short term. Thank you very much for your response.
Regards, Alan
