add 180 aliases to 1 365 mailbox

Hi,

You can connect to O365 powershell with the tenant global admin credentials and run command:

Set-Mailbox mailboxname -EmailAddresses @{Add='alias@somedomain.co.uk'}  (This command is manual command)

We also have a powershell script:

Please download the script for the same from link: https://gallery.technet.microsoft.com/office/Over-200-aliases-da06ad0b

Put all the names/addresses in a list and paste it in to Excel. Then concatenate the rest of the text on to each line using copy and paste. Save it as a test file with alias_addresses.txt

From power shell with admin right you need to run below command:

E.g.:
# .\Over_200_Aliases.ps1 -O365Admin admin@xxxxxx.onmicrosoft.com -O365AdminPassword Password123 -Mailbox_Name mailbox1 -Mail_Addresses_File_Path "C:\Temp\ExoVoice\alias_addresses.txt"

Where
# O365Admin - Administrator login ID
# O365AdminPassword - Administrator login password
# Mailbox_Name - mailbox with more than 200 aliases
# Mail_Addresses_File_Path - the pathe where the file with initial addresses list is saved e.g. email_addresses.txt
