A Technique to Import PST to Office 365 Shared Mailbox

The first and foremost thing is that the complete procedure performed by the Office 365 administrator. It means no other user associated with Office 365 cannot use this method for the same. Now, to understand the entire migration process clearly, we take an example here. For the overall workaround, we need an Office 365 admin account, a shared mailbox ID, and a O365 mailbox that is the member of shared mailbox.

  • O365 Admin ID:- pavan@cloudsystoool.onmicrosoft.com
  • O365 Primary Mailbox ID:- rennie@cloudsystool.com
  • Shared Mailbox ID:- support@cloudsystool.onmicrosoft.com

Let’s check out steps to import PST to Office 365 Shared Mailbox

Stage 1: Start With PST Files

It is advised to keep the PST folder or file name short and simple. Because many times naming convention create issues during the import process. Here, we save the PST file as ‘1.pst’. Plus, if the PST files are available on network server, so admin has to share the folder that consists of PST files.

Stage 2: Take Out SAS URL

Now, after preparing the PST file, it is the time to generate URL of Azure Storage Explorer. This step is very important because Azure store works as temporary storage for the PST file. And, this data file will further import into the O365 cloud. Now to get the SAS URL, you have to perform the following steps sequentially.

1. Login to O365 admin account. Here, we use pavan@cloudsystoools.onmicrosoft.com user ID. Then, click on Security & Compliance as shown in the screenshot.

 

 

2. You can either open the O365 Security & Compliance portal by pasting the following URL on browser.

https://protection.office.com/#/homepage

4. Click on +New import job to proceed the process.

 

 

5. After that, in Name your job section, enter a suitable name like ‘importpst’ and click on Next.

 

 

6. On the following window, select Upload your data option and click on Next.

 

 

7. In Import data page, click on Show network upload SAS URL to generate the URL.

 

 

8. Click on Copy to clipboard to copy the URL.

 

 

9. Next, paste the URL on notepad as shown in the screenshot.

 

 

Stage 3: Download Microsoft Azure Storage Explorer

After getting the SAS URL, the next step is to download Azure Storage application on the system in order to upload PST file. To do so, use the below steps.

1. Paste the following URL on search bar to open Microsoft Azure page.

https://azure.microsoft.com/en-in/features/storage-explorer/

2. Select the Operating system and click on Download Storage Explorer free.

 

 

3. After a few minutes, the application installed in the machine.

 

 

4. In order to establish the connection, right-click on Storage Accounts and select Connect to Azure storage

Note: Sometimes files will not be seen on the detailed pane, so it is advised to Reload the page. By doing this, the PST files will appear on the pane

Stage 5: Prepare CSV File

This is the most crucial step where we define that PST file should import into Office 365 shared mailbox. For this, admin needs to create a CSV or Comma Separated Value file that comprises all the information. To do so, use the steps below:

Steps to Create CSV File

1. Open Excel application and create a new sheet.
2. This sheet must include the following column.

  • Workload – Its value should be Exchange.
  • File Path – Leave this blank (Optional)
  • Name – Enter the uploaded PST name
  • Mailbox – Type shared mailbox ID (support@cloudsystool.onmicrosoft.com)
  • IsArchive – If the PST is archive type, then make it True. Else, type false.
  • TargetRoot Folder – Leave blank

 

 

Note: Make CSV file as per the standard.

  • I have access to the mapping file

 

 

2. Click on +Select mapping file and upload the previously created CSV (or PST Import Mapping file) file.

4. Finally, click on Save to add the file.

2. Once the analysis gets completed, the status becomes changed to Analysis Completed. Finally, you are ready to import PST into Office 365 shared mailbox.

 

 

3. Now, select the PST file that is going to be migrated and click on Ready to import to Office 365.

4. After that, to start the PST migration process, click on Import to Office 365 option.

 

 

5. On the following window, you have the option to either apply ‘import selective data’ through filter or migrate the entire data in shared mailbox. If you opt the ‘Yes, I want to filter it before importing’ option, then the following things can be performed.

  • Can Migrate data item of specific age
  • Can transfer specified type of message
  • Remove message of a specified people

6. Here, we select ‘No, I want to import everything’ option to import entire data of PST file into Office 365.

 

 

7. After that, click on Import data from the Filter your data window.

 

 

8. Finally, PST to Office 365 Shared mailbox migration process gets started. And, once the task gets completed, the status of PST file displayed as Success.

Note: Make sure you have enough amount of time. Because the complete PST import method takes long hours for completion.
