Can you import PST to iCloud without Outlook?

Certainly, it is possible to migrate PST files to iCloud without installing Outlook, but not instantly. PST files are not supported by iCloud natively. You have to prepare your data before moving it to iCloud. With CloudXena PST File Converter, you are able to transfer your emails and other data to iCloud without using Outlook.

Can You Upload PST to iCloud Mail Without a Tool?

In order to migrate the PST files to iCloud Mail manually, first, the PST needs to be imported into Microsoft Outlook. Subsequently, the synchronization process will need to be carried out through the service provided by Apple for Outlook. This approach can be used in small or simple migration cases from PST to iCloud mail, although it does not appear very efficient for large files.

Manual Procedure to Import Outlook PST to iCloud Mail:

Open the Outlook application and import the PST file into your existing Outlook account.
Install the iCloud for Windows program on your system.
Log in to the iCloud application using your Apple ID.
Activate syncing of Mail, Contacts, Calendar, and Tasks from iCloud settings.
Ensure that your Outlook account is linked successfully with iCloud services once the syncing is complete.
Drag and drop emails from PST imported folders to iCloud-enabled Outlook folders.
Wait until the selected data gets synced to iCloud servers from Outlook.
Test the migration process by accessing the iCloud Mail application.

What Went Wrong with the Manual Approach?

Despite the fact that the manual method can assist to import PST file to iCloud mail, this approach is not guaranteed to work with all people. The method involves heavy dependence on synchronization of Outlook and iCloud accounts, which may cause various problems when migrating data.

Some of the most common disadvantages are as follows:

This method consumes a lot of time due to the size of PST files.
Installation of Outlook is necessary.
Proper Outlook configuration is important.
PST files cannot be used with iCloud Mail.
Contacts and calendar entries may not synchronize correctly.
Partial synchronization can take place.
Batch PST file migration is impossible.

Due to this set of problems, the manual method may work perfectly fine for some but fail to deliver desirable results to others.
