Spark by Readdle is a popular email client for managing multiple accounts in one place. Many users also work in Microsoft Outlook, which stores its data in PST format. When you switch to Outlook, plan a long-term archive, or want an offline copy of your correspondence, you will need to export Spark Mail to PST.
Spark has no built-in option to save mail in PST format, so users look for other routes. This guide covers the manual method, its limitations, and a dependable professional solution for converting Spark Mail to PST.

Quick Answer: Can You Export Spark Mail to PST? Yes. Spark Mail does not offer a direct PST export, but you can export your Spark mailbox to PST in two ways. The manual method adds the same IMAP account to Microsoft Outlook && then exports the synced data through Outlook’s Import/Export wizard. The Cigati IMAP Backup Tool, which connects to the IMAP account used in Spark & saves the emails directly as a PST file with folders, attachments, and metadata intact. The manual method suits a single small mailbox, while the professional tool suits larger or multiple mailboxes. |
Spark does not keep your emails in a separate store of its own. It reads them from your email provider over IMAP, so every message still sits on the mail server. That makes it possible to add the same account to Outlook, let the folders sync, and then save the data as a PST file.
These points make the manual method less suitable for professionals, administrators, & anyone handling large volumes of email.
If you want to convert Spark Mail to PST without spending time on Outlook setup, the Cigati IMAP Backup Tool can handle it. Spark connects to your mail server over IMAP, & this software logs in to that same account to pull your emails. It then saves them straight into a PST file, so you do not have to add the account to Outlook or wait for it to sync first.
To understand each stage of the process, you can follow the detailed walkthrough on how Cigati IMAP software works. In general, you log in with your IMAP account credentials, select the folders, choose PST as the output format, set a destination, and start the export.

This combination of accuracy & flexibility is why most of the users prefer Cigati when they want to export Spark mailbox to PST.
Exporting your Spark mailbox to PST helps with migration, backup, & long-term archiving. The manual route through Outlook works for small, single-account needs, though it involves setup, sync time, and the limitations noted above. For a faster and more organized process, the Cigati IMAP Backup Tool lets you export Spark Mail to PST with selective options and complete data accuracy. Try the demo version first, and then move forward with the full export of your emails.
Ans. Spark does not store your emails locally. It only keeps a cache of messages on your device and this cache is not in a format that Outlook can read. The complete mailbox is always stored on your email provider’s server. That’s why exporting emails must be done through the IMAP account itself not by copying files from the Spark app.
Ans. Any account that connects to Spark via IMAP can be exported. This includes Gmail, Yahoo, iCloud, Outlook.com, AOL & custom domain email accounts. An IMAP-based tool only requires the email address, a password or app password and the correct server settings to access the mailbox.
Ans. Services like Gmail, Yahoo and iCloud block third-party apps from signing in with your password when two-step verification is enabled. An app password is a code created in your account’s security settings. It allows the export tool to access your mailbox without using or exposing your password.
Ans. Outlook 2003 and earlier versions use the ANSI format, which caps a PST file at 2 GB. Outlook 2007 & later use the Unicode format, which supports much larger files, up to 50 GB by default. If your mailbox is big, it helps to split the data into smaller PST files, for example by date range or by folder. Smaller files are easier to manage and open.
Ans. Store a copy on an external drive or a secure cloud storage service. You can also set a password for the PST file using Outlook’s data file settings. This protects your archive. Makes it available if your main drive fails.
