Steps to Import Contacts to Outlook from CSV (New Version)

Go to the side panel and click on the people icon.
In the ribbon, click Manage contacts >> Import contacts.
Click Browse >> pick CSV file >> click Open.
Click Import.

Steps to Import Contacts to Outlook from CSV (Classic Version)

In the upper left-hand corner of your Outlook ribbon, click File.
Click Open & Export >> Import/Export.
Select “Import from another program or file” >> Next.
Then, pick “Comma Separated Values” >> Next.
Within the “Import a File” box >> click browse >> Locate CSV >> double-click to pick it.
To instruct Outlook on how to handle duplicate contacts, you have the following options:
- Replace duplicates with items imported: Choose this if you have some contacts that are the same in both Outlook’s current database and the newly imported file. Here, Outlook prioritizes the information in the CSV over its own database and updates accordingly. This is the best option if you want to import contacts to Outlook from CSV files containing minor changes.
- Allow duplicates to be created: This is the default selection as it has the most lenient contact copying mechanism. Here, Outlook not only maintains its original data but also adds new contacts to the list, even if they are the same. You get the option to either combine or discard contacts of your choosing.
- Do not import duplicate items: This is the opposite of the first option. It means Outlook gives preference to its own database over the CSV that you provide. So only choose this option if you are uploading completely new contacts.
Press Next.
Within the “Select a destination folder” window, scroll till you see the Contacts folder >> Next.

Note: If you use multiple email accounts, carefully pick the Contacts folder of the email ID in which you want to place the contacts.

Press Finish.
Outlook starts to get the contacts from the source file. Once the import is done, the Import Progress box closes on its own.
You can view all contacts from the bottom of Outlook; just click on the People icon.

Add CSV Contacts to Outlook Through PowerShell Commands

For some users, clicking and working through endless boxes may be repetitive and boring. Moreover, the task of manually pushing the next button over and over again for multiple users is not easy. There is a way to automate the process via PowerShell commands. Let’s see how to do it.

On your desktop, launch a new PowerShell module as Admin.
To avoid interruption while running commands and scripts, configure the execution policy mode to RemoteSigned or Unrestricted.
```
Set-ExecutionPolicy RemoteSigned
```
Restart PowerShell to reflect the changes.
If you possess the credentials directly, type them in. Otherwise, use the command given below to get the credentials.
```
$UserCredential=Get-Credential
```

Start a PowerShell session from your machine:

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

Some commands (like ones related to Exchange Online) that we use are not present in the database by default, so we need to import them first. It can be done via:
```
Import-PSSession $Session
```
Make sure that the Exchange Online PowerShell V2 module is ready for use before you can import contacts to Outlook from CSV. Moreover, before that, you also need to download the PowerShellGet module.
```
Install-Module PowershellGet -Force
```
Press Y on your Keyboard to confirm the request.
Sometimes installation results in the following errors
- “PowerShellGet module (the NuGet provider) cannot be installed”.
- Warning: Unable to download the list of available providers. Check your internet connection.
Here are the steps to resolve the error.
Verify the PowerShell version:
```
Get-Host | Select-Object Version
```
Ensure it meets requirements; for example, PowerShell 5.1 or above is suitable.

Check security protocols:

[Net.ServicePointManager]::SecurityProtocol

If the output is either SSL3 or TLS 1.1 and below, update to TLS 1.2 or above version based on your hardware configuration.
Once all changes are done, you should upload CSV contacts to Outlook with no further interruptions. Run this command to install the module

Install-Module PowershellGet -Force -SkipPublicherCheck

Next, install the Exchange Online Management module with this command:
```
Install-Module -Name ExchangeOnlineManagement
```
For a new session, type in the following commands one by one.

$Credential=Get-Credential
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $Credential -Authentication Basic -AllowRedirection
Import-PSSession $Session

In our example, the files were located on the path C:\Temp\New_Outlook_contacts.csv (change your file path accordingly). Use the command and import contacts to Outlook Online in PowerShell.

Import-ContactList -CSV -CSVData ([System.IO.File]::ReadAllBytes(“C:\Temp\New_Outlook_contacts.csv”)) -DateCultureName “en-GB” -Identity user@domain.onmicrosoft.com

Some Tips to Follow After You Import Contacts to Outlook from CSV

For now, Microsoft only allows the import of contacts that are in CSV file format to Office 365.
Through this method, you can import contacts to Office 365 from your Gmail, Yahoo, Outlook, and Windows Live Mail accounts.
This procedure doesn’t allow the upload of multiple *.csv files to multiple user accounts at once.
No new folder of contacts will be created after uploading a CSV file.
The contacts will appear in the existing contact lists.

Note: In a professional setting, you may have to import files other than CSV. Like PST, MBOX, EML, etc. in such a scenario, you can go for the SysTools Office 365 Import Tool. Moreover, it is the best-in-class solution for all import needs.
