Now there are a number of valid reasons of why you might have wanted to do this (theirs was they were using an old version of Riverbed that didn’t support optimization using the MAPI-HTTP protocol), but as it turns out, the introduction of the MAPI over HTTP protocol to replace the legacy ‘RPC over HTTP’ protocol over 3 years ago was actually one of the precursors into allowing all this fancy Modern Authentication stuff to work.įor full details around what MAPI-HTTP protocol brought in and the benefits it introduced, I recommend reading this great blog post from the Microsoft Exchange team.īut in short, if you find that you have enabled Modern Auth as per the described steps, and you’re still getting the ‘basic auth prompt’ – I’d go ahead and check to see if the following registry key has been set (via GPO or otherwise) Key: HKEY_CURRENT_USER\Software\Microsoft\Exchange Now, for a large percentage of environments, this is probably not an issue – but if you are like a recent customer of ours, you may have specifically disabled the use of MAPI-HTTP. What isn’t explicity called out as a pre-requisite however is that your Outlook client also needs to also be running in MAPI over HTTP mode.
