  • It cannot export selective data altogether, for example, emails, calendars, and contacts.

  • The manual method to export Office 365 mailbox to PST requires technical expertise. Thus, non-technical users may find it challenging to operate.

Way-2: PowerShell cmdlets to Export Office 365 mailboxes to PST

Before using the PowerShell commands for Office 365 export mailbox to PST format, one has to create a search using the New-Compliance search option.

In the below script, I am searching for all my Office 365 mailboxes

New-ComplianceSearch “your_descriptive_name” -ExchangeLocation all | Start-ComplianceSearch

Then you need to use the following command to export the results of the search:

New-ComplianceSearchAction “your_descriptive_name” -Export -Format Fxstream

Wait until the exporting process is finished, and then use the below cmdlet to find the URL you need to download the converted data.

Get-ComplianceSearchAction “your_descriptive_name_export” -IncludeCredential | FL

The Results include two components for downloading the output file: the Container URL and the SAS token. Together, they make a URL.

Now we’ll use the PowerShell commands to export Office 365 Mailbox to PST. I’ve divided it into different phases so it’ll be easy to understand. First, launch EMS and proceed as follows.

(I can’t cover your scenario of data filtration or any other specified requirement, but I hope you’ll get an idea of how this works).

Phase1: Establish connection with Exchange Server:

  • To start, we need to establish a connection first, and for this, run the following PowerShell command

“$UserCredential = Get-Credential”

In the above command, enter the credentials of Office 365 users.

  • Now run the following command

“$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $UserCredential -Authentication Basic –AllowRedirection”

  • Then use the following command

“Import-PSSession $Session”

Phase2: Grant access rights to administrator:

Here I am granting sales@shovivsoftware.com full access rights to support@shovivsoftware.com

“Add-MailboxPermission – User sales@shovivsoftware.com –Identity support@shovivsoftware.com -AccessRights FullAccess -InheritanceType All”.

Phase3: Create Outlook profile for administrators:

Now you need to create the Outlook profile of the user to which you assigned the access rights earlier. In my case, it’s support@shovivsoftware.com

Once you create an Outlook profile, ensure the other user is also listed on the left pane. If not, wait for a few moments, as the access rights can take minutes to apply. Also, ensure you have enabled Cache Exchange mode.

Phase4: Use Outlook import/export to export Office 365 mailbox to PST

  1. Go to the File and click on the Open&Export from the left pane.
  2. Now, click the Import/Export and choose Export to a file
  3. Choose Outlook Data File.pst and select a mailbox which you want to export into PST format.
  4. Now choose the location to save the Office 365 PST file and select a duplicate filtration option.

The process to export Office 365 mailboxes to PST using PowerShell is completed here.

Now I know many of you have eliminated this method due to its lengthy process and commands. But apart from this, there are a few more things to keep your hand away from this method.

  1. It has a risk of data loss, and I have read several feedbacks where user mailboxes get corrupt between the process, or their mailbox doesn’t get listed in Outlook profile.
  2. You can only export a single mailbox at a time. No matter how small your mailbox or how many items it includes, you can only export a single mailbox at a time.
  3. Only the administrator can export the Office mailbox to PST, and they must have full access to other mailboxes. Otherwise, you can’t.

Now many of you might probably be thinking, is it possible to export the mailbox to PST from Office without any hassle and risk of data loss. So, yes, it is; you can simply use Shoviv Exchange Recovery Manager.

It is a tool recommended by Microsoft MVPs to Office 365 and Exchange administrators/users to manage their mailboxes.

I need to export PST files from non-Office 365 admin users, but I’m not sure if that’s even doable. I don’t want users to use the Office 365 portal; all am seeking a tool that allows me to tell them, “Hey, this person is no longer with the firm; please export their Office 365 mailboxes,” and all they have to do is open the software, select the user, and export to the local drive. Possible?


A great solution I found from this blog. It helped me to export all my mailboxes into PST from Office 365.

Excellent article for O365 users. However, I am not able to download the eDiscovery Export tool in the Edge browser. I’m not using any other browser. Can you fix this issue?
