Why Don’t Professionals Like the eDiscovery Method?

• The eDiscovery process to export Office 365 mailboxes to PST is long and takes a lot of time.
• It can’t export certain kinds of data, like emails, calendars, and contacts, all at once.
• There is no way to filter the items to export with this method, and there is a chance that data will be lost and mistakes will be made.
• If you want to export your Office 365 mailbox to PST manually, you need to know how to do it. So, people who aren’t tech-savvy may find it hard to use.

2nd Method: Export Office 365 mailboxes to PST using PowerShell cmdlets

Before starting the Office 365 mailbox export using the PowerShell commands, you have to create a search using the New-Compliance search option.

• I look for all of my Office 365 mailboxes in the command below.

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

• Then, use the following command to export the search results:

New-ComplianceSearchAction “your description” -Export -Format Fxstream

• Wait until the exporting process gets finished. After that, use the below cmdlet to get the URL of converted data.

Get-ComplianceSearchAction “your description export” -IncludeCredential | FL

• The Container URL and the SAS token are in the Results, so the output file can be downloaded. They come together to make a URL.

Now, we will use the PowerShell commands to export Office 365 Mailbox to PST. I’ve broken it up into different parts so you can understand it better. First, start EMS, and then do the following.

(I can’t answer your question about data filtration or any other specific need, but I hope you’ll get an idea of how this works.)

Phase 1: Connect with the Exchange Server:

• To get started, we must first make a connection. To do this, run the PowerShell command

“$UserCredential = Get-Credential.

• Enter the credentials of Office 365 users in the command above.
• Run the following command:

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

• Then use the “Import-PSSession $Session” command.

Phase2: Give the administrator the right to access:

• Here, I’m giving full access to support@regainsoftware.com to sales@regainsoftware.com.

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

Phase 3: Make an Outlook profile for a manager:

• Now you have to make the user’s Outlook profile for the person you gave access rights to earlier. It’s support@regainsoftware.com for me.
• Once you’ve created an Outlook profile, ensure the other user is also listed on Outlook. You may have to wait a few minutes for the access rights to take effect. Also, make sure your Cache Exchange mode is enabled.

Phase 4: Use Outlook import/export to export your Office 365 mailbox to PST.

• Go to the File option from the ribbon bar and click on the Open & Export option.
• Now, click on the Import/Export option and select Export to a file.
• Choose Outlook Data File.pst as a file format and choose a mailbox you want to export.
• Choose where to save the Office 365 PST file and choose a way to filter out duplicates.

Using PowerShell, this is the end of the process to export Office 365 mailboxes to PST. Now, I know that a lot of you have given up on this method because it has a lot of steps and commands. But besides this, there are a few other reasons why you shouldn’t use this method.

• It could cause data loss, and I’ve read feedback from users whose mailboxes became corrupted or didn’t show up in their Outlook profiles.
• Only one mailbox can be exported at a time. You can only export one mailbox at a time, no matter how small it is or how many items it has.
• Only the administrator can utilize this method to export the Office mailbox to PST. Also, they need full access to other mailboxes.
