Outlook 2016 Default Cached Mode Set to 3 Months RRS feed

  • Question

  • Hi,

    I have been testing the Upgrade to Office 2016 from Office 2010 in our environment.

    After upgrading Outlook 2016 has Cached Mode set to only 3 months, how do I configure this to cache all emails by default?

    Regards,

    Andrew

  • We shouldn't need to talk our remote users through configuring that, I was hoping for a setting the in package.

    I will just script out the configuration of this registry then:

    HKCU\Software\Policies\Microsoft\Office\16.0\outlook\cached mode
    DWORD:syncwindowsetting

  • Hi Andrew,

    By default, Outlook configures Exchange accounts to only synchronize a specific number of months, depending on the size of the disk. The following table shows the default Sync Slider setting for different disk sizes:

    Disk size                                                              Default setting
    Smaller than or equal to 32 GB                              1 month
    Greater than 32 GB, but smaller than 64 GB           3 months
    Equal to or greater than 64 GB                              1 year

    Generally, the cached mode Mail to keep offline setting is maintained in the Outlook profile settings in the Windows registry. If you want to administer this setting by using Group Policy, you can use the Group Policy templates. These are available from the following Microsoft websites:
    Office 2016: http://www.microsoft.com/en-us/download/details.aspx?id=49030

    The Group Policy template files for Outlook 2016 are Outlook16.admx and Outllk16.adml. If you use Group Policy to manage this setting, the following registry data is used by Outlook:

    Key: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\16.0\Outlook\Cached Mode
    DWORD: SyncWindowSetting
    Value: integer value (Decimal) specifying the number of months (use only the following values)

    0 = All (whole mailbox)
    1 = 1 month of email items
    3 = 3 months of email items
    6 = 6 months of email items
    12 = 12 months of email items
    24 = 24 months of email items

  • Thanks that's helpful.

    Is there any option to configure this setting for non-domain users as well?

  • Hi,

    Unfortunately, this Group Policy setting is only working for the Cached Exchange Mode deployment in the domain environment. For individual non-domain users, they can change how much mail to keep offline manually in Outlook 2016:

  • Hi,

    Based on my knowledge, there is no more settings for remote users about the Sync slides in Outlook. Additionally, this Sync Slider number is depended on the disk sizes by default.

    I think this is a better consideration for Outlook 2016 performance. If the Sync Slider is set to All and many messages are received in your mailbox. The Cached file is becoming larger size in your disk. If the Cached file (.OST file) is too large, there may be a performance issue in Outlook.

    Thanks for your understanding.
