During any PST data migration scenario, no admin wants to see the alert of PST import stuck on analysis in progress. However, sometimes, due to no fault of their own, they have to deal with it nonetheless. As there are multiple steps within the manual methods of PST import, the risk of such errors increases exponentially.

This stuck-at-0% error is encountered most commonly when organizations choose to use the Network upload method of PST file transfer. Before we can resolve the problem, let’s look at why this issue came up in the first place. This preventive action reduces the chance of this error occurring in the near future.

What can Cause PST Import Stuck on Analysis in Progress Explained?

This issue arises due to a wide variety of reasons. The main factor common in all the below-mentioned situations is that in every single one of them, Office 365 cloud platform is unable to correctly process the files. For an in-depth situation-wise analysis, go through the below-mentioned points:

Source-side corruption within the PST files leads to them being stuck during the import job. This is further amplified if the PST files were from an old Outlook desktop client. Additionally, as the manual method does no prior checks on the PST files the broken ones can slip through easily and cause the process to stop midway.

Sometimes, due to lack of knowledge or training, the person responsible for the uploading of files may not be able to configure all manual settings correctly. Leading to the import process being stuck in a loading state indefinitely. Moreover, the network upload method already has enough complications of its own. This is evident from the fact that even experienced admins can make such a mistake.

Lack of permissions is another reason why your Office 365 PST import in progress is stuck. The built-in security parameter that prevents unauthorized users from uploading PST files onto the cloud may stop you too if you don’t have the

One misconception that many admins share is that if they start many import processes simultaneously, at least one of them will complete. However, in practice instead of solving the issue, it has the opposite effect. As the network is now under more load, the chance that import will start and complete on time becomes slim to none.

Users who have reported this issue often cite poor network availability as a major cause. The network in itself may not directly contribute to your PST files being stuck. However, if another bandwidth-demanding task is using the same network in parallel the PST files may not get uploaded in time or even get stuck.

First of all, make sure the person assigned the job has the necessary training and adequate permissions. For configuring the permissions admins can

login to the Admin Center >> go to Roles >> Admin Roles >> assign the Import Export role

Delete the previous request and restart the PST import again. If this doesn’t work then users might have to look for alternative ways to import PST files into Office 365.

If permission-level issues are not the reason, check the PST files themselves. There is a high probability that a subset of PST files are broken, and hence the manual method fails. One option is to only upload the undamaged PST files. Otherwise, admins can first report the affected PST files and then reschedule the import request. Users may wish to use the ScanPST.exe utility; however, its reliability in such scenarios is questionable. Given the fact that it is prone to being stuck on Phase 7.

Ensuring adequate network availability is the job of the admin. In order to achieve a hurdle-free import admins must make an organization-wide announcement requiring the network to be free from any other heavy demands on the day of upload.

Removing password protection temporarily from PST files and reducing the average PST file size are a few other best practices that admins should follow. None of these solutions are sufficient. The manual method itself is problematic. The only real way is to skip over the manual upload method, so admins can use the utility explained ahead.
