I did replace my pst-file with the pst-file of my fried. Starting Outlook I'd all mails etc. from my friend in my outlook. But I did take note of the size of the 2 pst-files. My pst has a size of 3,xx MB, the pst of my friend a size of 198 MB, this after deleting all mails and contacts, i.e. with a empty pst. Before there were 25 mails in the inbox, 17 in the outbox and 28 contacts.
Now we will build a now pst-file on the PC of my friends and move the old one in the virus-container.
Thanks a lot for answering and regards
