Manual Configuration of Outlook for Exchange Online (Office 365)


Nowadays, everyone moves towards cloud. 

So, maybe someday your organization also plans towards cloud for your messaging system.
While in the coexist environment with your on-premise email server or other hosted email system, you might need the manual tweak/configuration at your migrated users in Office 365 for their Outlook connection before the autodiscover record is in place.

To manually configure Outlook:

1.       Obtain the required info from OWA:
a.        Log into OWA, in the upper-right corner, click the question mark (Help) icon and the click About.
b.       Locate and note the Exchange Client Access Server Name, Mailbox Server Name, and Host name.

2.       Create a new Outlook profile and choose Manually configure server settings or additional server types.

3.       Select Exchange and when prompted for the Exchange server you need to do a little detective work. Compare the values you noted above for Exchange Client Access Server Name and Mailbox Server Name. You should find that they both start with the same value. In my case they were HKNPRD0602CA011.apcprd06.prod.outlook.com and HKNPRD0602MB118.apcprd06.prod.outlook.com respectively. What you need is the part at the start that matches - in this case HKNPRD0602.

4.       Now, enter this value for the Exchange server and append .mailbox.outlook.com. Therefore, in my case the Exchange server was HKNPRD0602.mailbox.outlook.com.

5.       You can enter the user name as the user's display name, i.e. Megan Fox.


6.       Click More Settings. You'll likely get a warning that Exchange is unavailable. That's ok. Click OK.

7.       You may get another dialog prompting for the exchange server again, just click cancel and the extra settings window should appear.

8.       Click the Connection tab.

9.       Make sure that the Connect to Microsoft Exchange using HTTP check box is selected, and then click Exchange Proxy Settings.

10.    In the Use this URL to connect to my proxy server for Exchange box, type the server name you worked out in step 3 and append .outlook.com. Therefore, in my case, the URL was HKNPRD0602.outlook.com.

11.    Make sure that the Only connect to proxy servers that have this principal name in their certificate check box is selected, and then type msstd:outlook.com.

12.    Click to select the On fast networks, connect using HTTP first, then connect using TCP/IP check box, and then click to select the On slow networks, connect using HTTP first, then connect using TCP/IP check box.

13.    Under Proxy authentication settings, select Basic Authentication.

14.    Click OK two times.

15.    Click Check Names. Enter the user's Office 365 address and password. When the server name and the user name are displayed with an underline, click Next.

16.    Click Finish.
