    Import Outlook .pst files into O365 Outlook


    Hi all,

    I have just updated my W8.1 to W10 and discovered that the Mail app in W10 cannot import outlook .pst files or contacts,

    My old version of W8.1 is gone and I no longer have access to Outlook, all i have is the backup .pst files

    If I go down the path of buying O365 with Outlook, will I be able import those files into O365 outlook?

    :)

    Outlook PST File Problem

    That is exactly what I was going to suggest. Export everything to another PST file, delete the old(or rather move it out of the default folder) and replace it with the new PST file that you exported.

    Outlook PST File Problem

    Thanks again everyone. I just did an export on the troubled PST file to create a new PST file from it and the file size went from 3.9GB down to 850MB. Then I installed the new PST file into Outlook that I just created and removed the old PST file from Outlook and all seems to be working fine so far. I think I am good now, but I will give it some time just to make sure there are no problems before I delete the old file. Thanks again.

    Outlook PST File Problem

    Outlook .PST files are maxed at 2GB's anything over that and they become corrupted. You can try the scanpst.exe from above. Also this might help you.
