Outlook 2016 Keeps Ag For Aol Credentials Mac Works Just

Funny to mention that Outlook 2016 on mac works just fine, and as does mail on Windows however Outlook refuses to budge.

Ive tried a number of regedits and scripts but none seem to help resolve the issue for me.

Exchange 2016 is fully patched as of 18.11.18 with the latest CU.

Wondering if this is resonating with anyone Kind Regards, James.

Both exchange 2016 and 2019 and Outlook 2016 and beyond rely on autodiscover.

Unfortunately this environment is in production and in no area of this guide have i seen my version of Exchange mentioned.

So i would be very hesitant to make any of the changes you have recommended without it first going through a crash test in someones lab.

Also be aware, if they are behind any type of proxy, you need to ensure it is not asking for authentication instead of exchange.

You can check this by right clicking the outlook icon in the system tray with control held down and choose test auto discover.

I have found this to be the root cause of the problem: No external URL is available to access this mailbox with Exchange ActiveSync.

Your Exchange server configuration needs to be changed to allow access Kind Regards, James.

Outlook 2016 Keeps Ag For Aol Credentials Password Prompts Via

Unfortunately though I am still getting bombarded with password prompts via autodiscover with this Outlook client.

Please accept my apology as Id not had the chance to do this test until now; Ill write back with the results.

Dont just read it.

These are the steps Microsoft does when you call for help.

The active directory account seems fine and all is in order.

This is where the password prompt appears and both usernamedomain.com and domain does not seem to authenticate.

If you have a webmail link and they can successfully login, make sure your ECP is correctly configured (again, this is covered in Adams guide).

The problem is after that patch 2016 tries to contact Office 365.

Even if it is setup for exchange we just added these lines to lmhost as a bans-aid until MS fixes the patch.
