Hi There,

   I have 185 users that I have created in office 365. I got a request today to create 7 New rooms and to give the users full access to 7 mailboxes. I have created a csv file with the mailbox information in a column named mailbox. 

this command is fine if i want to add one user to the 7 mailboxes but how would i do it the other way? How do I add the 185 users to the mailboxes?

Import-Csv  C:\new.csv | foreach { Add-MailboxPermission  test@domain.com  -User  $_.Mailbox  -AccessRights  FullAccess }

Hi Andy,

This forum is for general questions and feedback related to Office desktop applications. Based on my research, if you want to grant permission via a .csv file, you will have to use some PowerShell script to make it work. I'd recommend you post a new question in the following forum for further assistance:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.
