Filter data when importing PST files to Office 365

Use the new Intelligent Import feature in the Office 365 Import service to filter the items in PST files that actually get imported to the target mailboxes. Here's how it works:

  • After you create and submit a PST import job, PST files are uploaded to an Azure storage area in the Microsoft cloud.

  • Office 365 analyzes the data in the PST files, in a safe and secure manner, by identifying the age of the mailbox items and the different message types included in the PST files.

  • When the analysis is complete and the data is ready to import, you have the option to import all data in the PST files as is or trim the data that's imported by setting filters that control what data gets imported. For example, you can choose to:

    • Import only items of a certain age.

    • Import selected message types.

    • Exclude messages sent or received by specific people.

  • After you configure the filter settings, Office 365 imports only the data that meets the filtering criteria to the target mailboxes specified in the import job.

The following graphic shows the Intelligent Import process, and highlights the tasks you perform and the tasks performed by Office 365.

Before you begin

  • The steps in this topic assume that you've created a PST import job in the Office 365 Import service by using network upload or drive shipping. For step-by-step instructions, see one of the following topics:

  • After you create an import job by using network upload, the status for the import job on the Import page in Office 365 Security & Compliance Center is set to Analysis in progress, which means that Office 365 is analyzing the data in the PST files that you uploaded. Click Refresh refresh to update the status for the import job.

  • For drive shipping import jobs, the data will be analyzed by Office 365 after Microsoft data center personnel receive your hard drive and upload the PST files to the Azure storage area for your organization.

Filter data that gets imported to mailboxes

After you've created a PST import job, follow these steps to filter the data before you import it to Office 365.

  1. Go to https://protection.office.com/ and sign in using the credentials for an administrator account in your Office 365 organization.

  2. In the left pane of the Office 365 Security & Compliance Center, click Data governance > Import.

    The import jobs for your organization are listed on the Import page. Note that the Analysis completed value in the Status column indicates the import jobs that have been analyzed by Office 365 and are ready for you to import.

    Analysis complete status indicates Office 365 has analyzed the data in PST files

  3. Click Ready to import to Office 365 for the import job that you want to complete.

    A fly out page is displayed with information about the PST files and other information about the import job.

  4. Click Import to Office 365.

    The Filter your data page is displayed. It contains data insights about the data in the PST files for the import job, including information about the age of the data.

  5. Based on whether or not you want to trim the data that's imported to Office 365, under Do you want to filter your data?, do one of the following:

    1. Click Yes, I want to filter it before importing to trim the data that you import, and then click Next.

      The Import data to Office 365 page page is displayed with detailed data insights from the analysis that Office 365 performed.

      The graph on this page shows the amount of data that will be imported. Information about each message type found in the PST files is displayed in the graph. You can hover the cursor over each bar to display specific information about that message type. There is also a drop-down list with different age values based on the analysis of the PST files. When you select an age in the drop-down list, the graph is updated to show how much data will be imported for the selected age.

    2. To configure addition filters to reduce the amount of data that's imported, click More filtering options.

      Configure the filters on the More options page to trim the data that's imported

      You can configure these filters:

      • Age   Select an age so only items that are newer than the specified age will be imported. See the More information section for a description about how Office 365 determines the age buckets for the Age filter.

      • Type   This section shows all the message types that were found in the PST files for the import job. You can uncheck a box next to a message type that you want to exclude. Note that you can't exclude the Other message type. See the More information section for a list of mailbox items that are included in the Other category.

      • Users   You can exclude messages that are sent or received by specific people. To exclude people who appear in the From: field, To: field, or the Cc: field of messages, click Exclude users next to that recipient type. Type the email address (SMTP address) of the person, click Add New icon to add them to the list of excluded users for that recipient type, and then click Save to save the list of excluded users.

        Note: Office 365 doesn't show data insights that result from setting the People filter. However, if you set this filter to exclude messages sent or received by specific people, those messages will be excluded during the actual import process.

    3. Click Apply in the More filtering options fly out page to save your filter settings.

      The data insights on the Import data to Office 365 page are updated based on your filter settings, including the total amount of data that will be imported based on the filter settings. Note that a summary of the filter settings is also shown. You can click Edit next to a filter to change the setting if necessary.

      The data insights are updated based on your filter settings

    4. Click Next.

      A status page is displayed showing your filter settings. Again, you can edit any of the filter settings.

    5. Click Import data to start the import . Note that the total amount of data that will be imported is displayed.

    Or

More information

  • How does Office 365 determine the increments for the age filter? When Office 365 analyzes a PST file, it looks at the sent or received time stamp of each item (if an item has both a sent and received timestamp, the oldest date is selected). Then Office 365 looks at the year value for that timestamp and compares it to the current date to determine the age of the item. These ages are then used as the values in the drop-down list for the Age filter. For example, if a PST file has messages from 2016, 2015, and 2014, then values in the Age filter would be 1 year, 2 years, and 3 years.

  • The following table lists the message types that are included in the Other category in the Type filter on the More options fly out page (see Step 5b in the previous procedure). Currently, you can't exclude items in the "Other" category when you import PSTs to Office 365.
