Company Portal Profile installation failed on iPhone - Status code 400

Hello,

 

I've been managing mobile devices through InTune for almost a year. 

Most of our devices are iOs - I add the phone to the Apple Business Manager - wait for it to appear in InTune - then install company portal, and log my user in. This pushed out software etc to the phone.
I successfully set one up on Thursday.

Today I'm trying to set a new one up and I can't get the Company Portal profile to install. I get a long error, ending in Status Code 400. 
This error happens often, but usually if I try again, it works. Recently I thought I had discovered the issue, and have started ensuring the iPhones are updated before installing Company Portal. But nothing works with this phone.

Any suggestions?

 

Thanks in advance!
Amber

    A Status Code 400 during Company Portal profile installation on iOS (Intune) is typically a client-side enrollment or configuration issue, not a transient service failure—especially if retries consistently fail.

     

    Mainly, the two main cases are:

    1- Device Already Exists in Intune (Duplicate Object), Intune may already have a record for this device (same serial/UDID).

     

    2- Enrollment Profile Misconfiguration, such as user affinty mismatch or Authentication method conflict.

     

    3- Some condetional access auth failure.
