Hi Everyone,
I have inherited a few old domains that are .local, but the primary email domains are .com.
When performing a "Test E-Mail AutoConfiguration" using the primary SMTP address which is automatically populated internally on the domains, I receive the following errors:
GetLastError =0; httpStatus=401
GetLastError =0; httpStatus=200
However, if I use the UPN, I receive the correct SCP record as it authenticates properly.
Without adding the primary SMTP domain to AD and modifying all the users' UPNs.
Are there any alternatives or fixes?
