How to import PST to Office 365 – Exchange Online mailbox

1/ Make sure you have the required permissions

Before importing a pst to an exchange mailbox, make sure your are assigned the role Mailbox Import Export, it’s a pre requisite for using the below process.

2/ Prepare your pst import mapping file

Supposing the pst file you want to import is located in a network share named : \\myPC\ImportPST

Your mapping file should contains the below data

Name : pst file name

Mailbox : the destination mailbox email address

IsArchive : FALSE – because the mailbox we are importing is not an archive mailbox

TargetRootFolder : “/” – we want to import the data to the root folder of the destination folder. If you want to import data to a folder named “myImport” for example, use this synctax : /myImport

In this example, here is how my mapping csv file looks like. I saved it on my computer as import.csv

You are almost ready to import your PST data to an Office 365 mailbox.

3/ Start the import job

Connect to the Security and compliance center (https://protection.office.com), then under Information governance, select Import > New import job

Name your import job with 2-64 lowercase letters, numbers or hyphens, must start with a letter, no spaces

In the next page, select Upload your data > Next

On the import data page, click on Show network upload SAS URL and copy it to clipboard.

Click on the link Download Azure AzCopy and install it.

The default location of AzCopy will be C:\Program Files (x86)\Microsoft SDKs\Azure\AzCopy\

You are now ready to begin the data import. Open a PowerShell and run the below command to copy your pst file using AzCopy to a temporary Azure Storage from which you will copy the data to destination mailbox.

cd "C:\Program Files (x86)\Microsoft SDKs\Azure\AzCopy\"

Then run the below commandline replacing the value with your own data

.\AzCopy.exe /Source:"\\myPC\ImportPST" /Dest:"<Copy here the previous SAS URL>" /V:"\\myPC\Logs\AzCopy1.log" /Y

Back to the Import data page, check the two checkboxes “I am done uploading my files” and “I have access to the mapping file” and go on the next page clicking on the next botton.

Now click on “Select mapping file” and choose the the mapping csv we previously built. Validate the file and Save the job to begin file analysis.

A job analyse will start. Once it’s done you will be able to import the PST data to the destination mailbox.

Click on the link “Ready to import to Office 365”, on the next page click on “Import to Office 365” button and start the import job.

Select the Next button, and start the data importation on the next page. Once you are done, you will

4/ Check if the import job was successful

You are done with the copy, now, let’s check in the destination mailbox if the data has been well copied. In outlook, you will see a folder named <source email address>, it’s the email address of the mailbox from which you have exported the pst file.

If you had chosen to import the pst file into a folder named /importPST, you would have seen in Outlook, under that folder another folder named <source email address>

Another way to check your pst import result is use a powershell command :

Get-MailboxFolderStatistics <destination mailbox> | Out-GridView

Et voilà 🙂

In the Security and compliance center (https://protection.office.com), under “Search” click on “Content Search”

In the content search portal, start a New search

Check “Specific location” and select modify to specify the location/mailbox you want to export the content from.

Save and run to start the content search process.

How to grant read-only permission on a MailBox

In this post I will show you how to grant user Perry Brill read-only permission on the mailbox of Joe Dan using PowerShell.

The first thing to do is to find all the folders present in Serge Boss mailbox then grant read only permission on those folders to John Doe.

Let’s go with the fistr step :

To find the folders in the mailbox, use the below commandline 

Get-MailboxFolderStatistics -Identity <mailbox identity> | Select-Object Identity

To grant access to a particular folder, use this commandline

Add-MailboxFolderPermission -Identity <Folder Identity> -User <User who needs access> -AccessRights <Type of Access>

To grant read-only access to all the folders, you must apply the previous command to all the folder. The easiest way is to use a loop. I propose you a function to reach that goal.

function Add-PermissionOnAllMailboxFolders {
    param (
        [Parameter(Mandatory = $true)]
        $Identity,

        [Parameter(Mandatory = $true)]
        $User,

        [Parameter(Mandatory = $true)]
        [validateSet("Author","Reviewer","Contributor")] #Find complete list of permission on https://docs.microsoft.com/en-us/powershell/module/exchange/add-mailboxfolderpermission?view=exchange-ps
        $AccessRights
    )

    $ExcludeFolders = ":\Top of Information Store",":\Recoverable Items",":\Audits",":\Calendar Logging",":\Deletions",":\DiscoveryHolds",":\Purges",":\SubstrateHolds",":\Versions",":\Sync Issues",":\Yammer Root"
    $alias = (Get-Mailbox -Identity $Identity).alias
    
    Add-MailboxFolderPermission "$($alias):\" -User $User -AccessRights $AccessRights

    (Get-MailboxFolderStatistics -Identity $alias).Identity | Foreach-object {
        $folder = $_.replace("$alias\","$($alias):\")
        if ($folder.replace("$alias","") -notin $ExcludeFolders) {
            Add-MailboxFolderPermission $folder -User $User -AccessRights $AccessRights
        }
    }

}

Run the script to load the function and then use the commands below to grant the permissions according to your need

To grant read-only permission

#Reviewer : FolderVisible, ReadItems
Add-PermissionOnAllMailboxFolders -Identity "Joe Dan" -User "Perry Brill" -AccessRights Reviewer

To grant the other type of permission

#Author : CreateItems, DeleteOwnedItems, EditOwnedItems, FolderVisible, ReadItems
Add-PermissionOnAllMailboxFolders -Identity "Joe Dan" -User "Perry Brill" -AccessRights Author

#Contributor : CreateItems, FolderVisible
Add-PermissionOnAllMailboxFolders -Identity "Joe Dan" -User "Perry Brill" -AccessRights Contributor

Now you can add the mailbox to the user Outlook and access it content

The mailbox now appears in your outlook.

Exchange Online Powershell module installation error – Application cannot be started. Contact the application vendor

This morning when trying to install the PowerShell Module for Exchange Online from the ECP,

Install Exchange Online PowerShell

I came accross this error message

Exchange Online - Cannot Start Application

Even though this is not a very serious issue, it may cause you lose your time.

So to avoid this error message, use INTERNET EXPLORER to connect to the ECP and then the INSTALLATION WILL BE POSSIBLE.

Thank you.

Cannot change Profile Picture on Teams

One day, an Office 365 user asked me why he cannot change his Teams Profile Picture. After a few check, we found that a license option was missing on his Office 365 user account. This user account was missing an Exchange Online license.

So, to enable picture adding to a Teams profile, you need to have an Exchange Online license enabled for this profile. Once it’s done, wait for un while or restart Teams and you will see the “Change picture” option appear.
