    Why is my outlook.pst file is growing rapidly on the disk?


    The outlook.pst file is normally around 50 MB (for the past two years). I added some reminders (maybe 5% more) and it grew to 80 MB. I added some more reminders (maybe another 5% more) and it grew to 115 MB. I emptied the Deleted Items in Outlook and rebooted. The size is still 115 MB.

    The text of reminders that I have added should have increased the size by no more than 2.5 MB each time.

    Is the .pst file becoming corrupt? Will it continue to grow?

    I am using Windows 10 and Outlook 2016. I have Tasks with just text. There are no emails in my Outlook. This computer has never been on the network, and Outlook has no configuration with a mail client. There are no viruses on the computer that I can tell. Since it has no connection to a network, I do not see how a virus could be the problem.

    :)

    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.

    Why is my outlook.pst file is growing rapidly on the disk?

    Outlook PST File Problem

    My Outlook PST file has now grown to nearly 4GB. I have deleted tons of stuff, emptied the deleted items mailbox, and I have done a Compact Now on the PST file a few times, but the file size never gets smaller. It just keeps growing in size instead. My guess is that it shouldn't even be 1GB at this point. Is there some easy thing I can do to rebuild the file using just the emails, contacts, and folders I want to keep so that the file runs smoothly and is optimized down to its proper size? Cheers. Marc
