Outlook .ost files taking alot of space on Shared PCs

    Question

  • Hello Guys,

    We have bunch of shared machines running out of disc space due to multiple profile .ost files. I wonder if there is a way to set up a policy to minimize a machines email cache to a maximum of one month rather than the default one year. We are basically looking for a possible way to reduce the outlook .ost files footprint on the disk. Thank you.

    Regards,

    Pooriya

  • Hi Pooriya,

    You can use the Cached Exchange Mode Sync Setting policy to configure the default Sync Slider for your Outlook users. Or, you can distribute the following registry key to your users to achieve the same goal:

    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Cached Mode
    DWORD: SyncWindowSetting
    Value: 1 to set the sync slider to 1 month.

    See the following Microsoft KB article for more details:
