No. You can also reduce a local PST file, which helps compact the file's size. Consult your Microsoft documentation on how to configure the size limit for PST files in Outlook. Why is my PST file larger than the size limit? It's possible your PST file might exceed the size limit. That is, once you select a larger size and your PST file grows to that size, you can't go back. Why is a size option not available? If your local PST file already exceeds one of the size options, the option is no longer available in the Set Mailbox Size dialog. Why is the Set mailbox size limit option not shown? This command isn't available if your mailbox size limit was set using a Windows Registry key. Note that depending on your computer, a larger size might degrade performance when searching and indexing. Your size options are 1 GB, 2 GB, 4 GB, or Unlimited.

All messages remain available in your Gmail account on the web. If you run out of space locally, older mail is removed from your computer and replaced with newer messages. The amount of mail stored locally is instead limited by Microsoft Outlook's mailbox size. The cloud can hold up to 30 GB of mail (or more), which is much more than you'd typically want to keep on your computer. When you use Google Workspace Sync for Microsoft Outlook (GWSMO), your mail is stored both remotely in the cloud, and locally in a PST mailbox file on your computer.
