What is this article about?

When you use G Suite Sync for Microsoft Outlook (GSSMO), your mail is stored remotely in the could, and cached locally on your computer.  Your UA Gmail account can hold many GB of mail; however, by default GSSMO only syncs 1 GB of mail to your Outlook client. This article will explain how-to increase the amount of your Gmail that is synced to an Outlook client using GSSMO.

What materials do I need?

  • UA Gmail account
  • A computer running Microsoft Windows operating system
  • Microsoft Outlook
  • G Suite Sync for Microsoft Outlook (GSSMO) client

How do I use this technology?

You can adjust GSSMO's local mailbox size by doing the following.

  1. Click the GSSMO icon in your Windows taskbar.
    • The GSSMO icon appears in your taskbar, typically next to the clock. From here you can access the GSSMO settings.
    • If you don't see the GSSMO icon, it might be automatically hidden by Windows. Click the small white up arrow on the taskbar to show all icons.
    • Note: The GSSMO icon will only appear if GSSMO is running.
  2. Choose the Set mailbox size limit.
  3. Select a mailbox size from the dialog that opens. Your options are 1 GB, 2 GB, 4 GB, or Unlimited*. Note that depending on your computer, a larger size might degrade performance when searching and indexing.

* Note: The unlimited size option does not really mean unlimited. Microsoft Outlook limits the size of the local PST file, the exact limit depends upon which version of Outlook you are running. If you select the unlimited​​​​​​​ mailbox size in GSSMO, your PST file will not exceed the limits imposed by Outlook.

Outlook PST default size limits

  • Outlook 2007: 20 GB
  • Outlook 2010, 2013, 2016, or 2019: 50 GB

For Outlook 2016, and later these defaults can be increased by changing a registry setting; however, you should consider the available space on your local storage before doing so.
