Common Queries Asked by Users

Now, to understand the problems or errors faced during PST import process, consider some of the queries asked by the users:

User Query 1- A few hours ago, we were importing PST files to Office 365 with the help of AzCopy Tool. And, suddenly, it displays the status that Office 365 import failed. The details it displayed are that the process is 70% complete. Now, I am looking for a solution that lets me resume the job from where it was left off or do I have to restart the job? Some of the sites over the internet suggested to the delete the entire online archive process and starting importing all over again. I do not know why this Office 365 PST import failed as previously I have imported many times without any failure.

User Query 2- When I was uploading multiple PST files in batches, the upload worked perfectly during the upload process for the first 3 batches. But as I initiated a new job and created a new sas-url to replace the URLs in the copy job, it displayed a 403 error message: I am confused now and do not know how to proceed further. Can anyone suggest me some other simple way to import multiple PST files to Office 365?”

User Query 3- User I was trying to import 5 PST files to Outlook 365 via a web-based import application. I have recently uploaded the files with the help of Microsoft Azure Storage tools. After that, created a ‘PSTImportMappingFile.csv’ file that helps Office 365 in determining which PST belongs to which mailbox. However, most of the mailboxes work fine but some of them return the following error:

“Please create Primary and Archive Mailbox for and create a new job”

So, I created a new job but the things are still the same. Does anyone know what is exactly happening?”
How to Troubleshoot Office 365 Import Failed Error?

This section of the blog will let users know the most common scenarios with a short explanation and some hints for troubleshooting. Now let us discover what are the problems that may cause these errors.

How to Troubleshoot Office 365 Import Failed Error?

first, there are some keytakes which you should prefer.

Problem #1: Import Process Failed at 0%

Error Message:
“import failing to initiate”
or
“The operation couldn’t be performed because ‘archive1@contoso.com’ matches multiple entries.”

Solution: In the CSV mapping file for the target mailboxes, a user should use unique identifiers like ExchangeGUIDs rather than using the primary SMTP address of the users.

Explanation: The main reason behind this import data to Office 365 error is the soft deletion of mailboxes or mail users. They will combat the targeted user’s active mailboxes when they resolve the primary SMTP address.

Problem #2: If a user has created a job with the deleted job name, it displays an error.

Error Message: “Job with the same name already exists”.

Solution: Always use unique names for the jobs to import PST files.

Explanation: The job names must be unique always, to avoid any such restriction in the future.

Problem #3: There is a difference between the data that is Supposed to be imported and the data that is imported actually.

Error Message: Not Applicable

Solution: Simply execute the following command:
Get-MailboxImportRequestStatistics -identity “Name of Import\GUID |fl

After that, you need to have a look at the following parameters:

• EstimatedTransferSize: 1.211 GB (1,300,827,963 bytes)
• BytesTransferred: 64.36 MB (67,487,118 bytes

Explanation: After looking at the figures given above, it is clear that some of the items are already there in the targeted mailbox at the time of import. Hence, to avoid duplicates, some items were left.

Problem #4: CSV mapping files are not validated during the import process.

Error Message: “The specified file could not be found. Please ensure that the path to the file is correct.”

Solution: A user simply re-check the file path in the CSV mapping file.

Explanation: The possible reason behind this is the difference in the cases of file paths.

For example, the path in the mapping file “/test1/OutlookPST/IMPORT/batchA” and the file stored at the Azure Storage account is at: “/test1/OutlookPST/Import/Batcha”. To overcome such an issue, a user is suggested use “/test/OutlookPST/Import/Batcha” in the CSV mapping file.

Problem #5: Office 365 Service is not available

Error Message: Error 403 Forbidden

Solution: Double-check the source and destination path

Explanation: This problem mainly arises when the source and destination are not proper. Moreover, the proper way of using Azcopy Tool is with the help of the below-mentioned command:
AzCopy.exe /Source: /Dest: /V:
