Hi everyone,

I'm trying to connect a Microsoft 365 mailbox to Zoho TeamInbox (EU region) via OAuth and keep running into an issue.

Steps I followed:

1. Create a Shared Channel → Email Channel → Microsoft (OAuth)

2. Microsoft login window opens → I authenticate successfully

3. After authentication, I get this error:

{"status_code":404,"err_msg":"Invalid URL","iam_err_msg":"URL_RULE_NOT_CONFIGURED"}

4. When I try again, the process loads but no channel is added.

What I've already checked/done:

- IMAP is enabled for the mailbox in Microsoft 365

- Admin consent granted in Azure Entra ID (Enterprise Applications)
