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.

Why Users Export Emails from Spark Mail to PST

  • Moving from Spark to Microsoft Outlook calls for data in PST format.
  • A PST file gives you an offline copy of important conversations.
  • Business users keep email archives for audits & reference.
  • A PST file makes it simple to carry mailbox data to a new computer.
  • Emails stay readable in Outlook even without an internet connection.

Tips Before You Begin

  • Keep the account password or app password nearby, since the tool will ask for it when you sign in.
  • Open your email account settings and make sure IMAP access is enabled, otherwise, the software will not be able to connect.
  • PST files can grow large for big mailboxes, so choose a destination with plenty of free space.
  • Once the export is done, save one more copy of the PST file on an external drive or a secure cloud location. So your data is protected if something happens to the original. 

Manual Method to Export Spark Mailbox to PST

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.

Limitations of the Manual Method

  • Microsoft Outlook must be installed & configured on your system.
  • Large mailboxes take a long time to sync before export can begin.
  • Moreover, each account must be added and exported separately.
  • Passwords, app passwords, & two-step verification settings must be handled correctly.
  • The process supports only the PST output format. 
  • In this method, Outlook cannot connect to IMAP server. 

These points make the manual method less suitable for professionals, administrators, & anyone handling large volumes of email.

Frequently Asked Questions

Q1. Does Spark store emails locally? Can I copy them from the Spark folder to create a PST file?

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.

Q2. Which account types in Spark can be exported to PST?

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.

Q3. Why does the tool ask for an app password of my regular password?

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.

Q4. What is the size limit of a PST file?

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.

Q5. How can I keep the PST file safe after the export?

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.
