Did you contact the author of the CmdLet with your question?

I am attempting to write a script to import and keep up to date contacts from our CRM system in O365 contacts databases (primarily so that the iPhone contacts contact up to date copies of our business contacts).

I have scripted connecting to O365 as an admin user and confirmed that it works.  The problem comes when I try to import a test CSV file.

When I run 

Import-ContactList -CSV -CSVData ([System.IO.File]::ReadAllBytes("C:\tmp\contacts.csv")) -Identity <userid>

I get this error

An error occurred while saving a contact to the mailbox. Please contact your email admin. The failure 
occurred while importing contact number 1 from the file. Contacts imported: 0.

I have no idea where to look to debug this.  I have tried both as an admin user with delegated access to the mailbox in question and as the user of this mailbox itself.

Hi Rob,

This is the forum to discuss questions and feedback for Microsoft Office client. There is not so much about Office 365 Admin aspects here, I would suggest you to post in the dedicated forum of Office 365 Community, where you can get more experienced responses:

http://community.office365.com/en-us/f/default.aspx

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.
