Manual Approach to Convert PST to ICS File

Microsoft provides a manual solution for users to convert PST to ICS format. However, this method comes with unavoidable limitations that we will discuss further in the blog. If you still want to proceed with this manual approach, then follow the steps given below.

This manual method is divided into two parts. First and foremost, you need to import PST to Outlook. Once that is done, proceed to the next part, i.e., exporting the PST calendar into ICS format. Here is how to execute the process.

Restart the MS Outlook email client on your system.
Next, head to the mailbox folder of the imported file and select “Calendar” from the list.
Now, choose which calendar you would like to convert to ICS format from the provided options.
Then, click on “File” and from the dropdown menu, select the “Save Calendar” option.
Afterward, browse and select the preferred destination to save the resultant ICS files.
Upon doing so, select the preferred “Date Range” from the provided options and then click on “OK”.
After you choose all the details you want, click on the “Save” button to complete the process.

So, this is how you manually convert PST to ICS format. As discussed above, there are certain unavoidable limitations and hindrances attached to this method. Let us have a look at them. If you do not want to deal with the limitations, feel free to jump ahead to the expert-recommended solution.

Drawbacks of the Manual Approach

This method is Outlook-dependent, which means you must have the Outlook application installed on your system in order to use this technique.
The method involves two different parts, which make it extremely lengthy and time-consuming for bulk conversions. Due to this, this solution is not recommended for users who want to convert PST to ICS in batch.
You must have appropriate technical Knowledge to execute this method. If you do not have any technical experience, then there is a high chance of errors, which may result in data corruption or data loss.

As you see, these limitations make this manual solution an unappealing choice for users. Thus, to save time and increase efficiency, technical professionals recommend an automated utility that we have discussed in the following segment.
