AUTODISCOVER ISSUES WITH OUTLOOK/EXCHANGE

Had three instances of this problem in the last week:

Step 1

In Windows 10 and Windows 8, press the Windows Key + R to open a Run dialog box. Type regedit.exe and then press OK.

In Windows 7, click Start , type regedit in the Search programs and files box, and then press Enter.

Step 2

Locate and then select the following registry subkey:

HKEY_CURRENT_USER\Software\Microsoft\Office\x.0\Outlook\AutoDiscover

Step 3

Create the following DWORD value and give it a value of 1.
