Outlook bypasses AutoDiscover and connects directly to Office 365 mailbox? Has this happened to you, it has me, TWICE in a week, it turns out it’s because of this:
What this means for the end user is if you have a MS Exchange account hosted on ISP for example then you cannot connect to it, what the hell are Microsoft doing, this year has speen aspate of stupid updates that take over and screw up the system for general use :/
Anyway, enough moaning, this is how you fix it 🙂
If you would rather NOT edit the registry, here is a simple .REG file that will do the work for you, simply extract this file, double click it and reboot – JOB DONE Fix Outlook 2019 for Exchange
Or this is the normal way for techies:
In Windows 7, click Start , type regedit in the Search programs and files box, and then press Enter.
2. Locate and then select the following registry subkey:
3. Create a 32Bit DWORD value and give it a value of 1. (if it exists just change it to 1).
It should read like this as a full tree
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\office\16.0\outlook\autodiscover DWORD: ExcludeExplicitO365Endpoint Value = 1
REBOOT the computer.
