[enter image description here][1]Since changing the primary mail address of my Office 365 account, I am no longer able to set it up in Outlook.

At first, all I could do was not retrieve any mail, so I tried to set up the account again - unfortunately unsuccessfully.

Every time I try to add the account, I get the error 83750009: "JSON value not found.".

After that I removed the profile, uninstalled the whole Office and removed remaining references / registry keys as described here:

I have also tried setting up the account, as an Azure-AD account, directly in Windows. Here I get the same error message.

Unfortunately the problem still persists, even Microsoft support could not solve the problem after 10 days. Do any of you have any ideas?

Would you be able to show results of get-mailbox |FL get-azureaduser |FL get-msoluser |FL Get-AzureADUserRegisteredDevice

Does it happen only on a single device?

Try removing the device from AzureAD and dsregcmd.exe /debug /leave to remove the machine and try re-registering it.
