Hi,
Thanks for posting in Microsoft Q&A forum.
==>How to remove the old account info from company portal ?
We can't remove old company account in client side, it should be removed from Intune portal firstly.
If possible, you can give the Serial Number/IMEI of the Android phone to the security group or IT department in your former company. They may search by the Serial Number/IMEI and find your phone, then remove it from Intune portal. And then you can add new company details in company portal app.
Thanks for your time.
Best regards,
Simon
