Logon Credential Prompts When Using Third Party Exchange Providers

[E-Double]

After migrating to a third party Exchange provider (i.e. with an external
domain) the MS Outlook clients with Full Exchange prompt for authentication
credentials to sign-in with their password every time they open Outlook. Is
there a setting or a script (or anything at all) that could be run or
implemented in order to disable the constant and frequent prompting for a
password every time they open Outlook.

TIA,

e.

This is a newsgroup to discuss the client, not the mail server. There
are newsgroups where you can ask about Exchange. Those folks might know
how to handle authentication for clients when those clients are
off-domain.

When you login into a domain, those same login credentials get reused
when you connect to the Exchange server in that same domain. Since the
Exchange server that you use is not in your domain (if you even have
one), you get prompted to prove you are authorized to use that resource.

So why not ask for help from whomever you are paying for this mail
server service who is external to your company's network?
