Outlook for Mac 2011 cannot connect to Exchange server

Hello All,

Environment: Exchange 2007 SP3, Office for Mac 2011, 5 iMac (OSX 10.10 x2, OSX 10.9 x3) do not join domain

When setting up outlook,

for OSX 10.10, we can connect to a mailbox automatically by input email address & password.

for OSX 10.9, after input the email address & password, the autodiscover service seems not working, so i need to enter the server info (EWS details copy by successful setting from OSX 10.10), but it still fail to connect, the indicator icon still in orange & no error popup.

We also contact Microsoft for help but they just suggest to upgrade the OSX, we are no idea, if any help here will be really appreciated. Many thanks.

iMac, OS X Mavericks (10.9.1)

1. Make sure you quite Outlook and other Office apps. Go to KeyChain Access

2. Search "Exchange" under Login --> All Items and delete everything

3. Search "Office" and delete everything

4. Search "ADAL" and delete everything

5. Launch Outlook

6. You will get the activation prompt and then if account is already added you will see the password prompt for app and ADAL again. Please do 2-Factor Authentication if asked to and you should be able to login.
