Outlook 2013 Possible interference by Telstra ISP with Hotmail Password

[td47]

Visiting a relative in Perth Australia, my OL 2013 on my laptop keeps asking for the Hotmail password (it is MS Exchange mode as you know). However, there is NO issue with this account (the other 2 accounts, a POP3 and a Gmail IMAP are working fine), and I CAN successfully login via the "login.live" web UI access, using the same, correct password, that has not been changed, so i KNOW I have not been hacked. Never had an issue with the home ISP at all.

He is using the Telstra ISP, and I spotted an interesting post on another forum linked below, suggesting that Telstra is interfering in some way, stopping the Exchange server getting the password parsed. linking outlook to another server

Just to ask about another possible gremlin getting in the way of password authentication, I also saw this, in relation to the February posts about the infamous Microsoft shared calendar sync issues. I am not sure if this ADAL functionality is relevant or not:
"
1. Connect to Exchange Online With PowerShell
PowerShell:

Connect-ExchangeOnline
Set-OrganizationConfig -OAuth2ClientProfileEnabled $true

2. Regedit Users Computer

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity

Add DWORD 32: EnableADAL Hex Value:1

Close Outlook 365 reopen and there you go."

With a Hotmail account, the PowerShell is useless (you can't use it). The reg key may help in Outlook 2013.

I am having this same issue. It keeps prompting for my Hotmail password over-and-over. It's worked fine for years, no change other than what comes as part of mandatory Windows updates to Office. I tested to see if it was possibly corruption to my local OST account, or if it is a new policy by Microsoft, and I think it is the latter. Read how I tested this theory below.

I created a new login account on my PC so I would have a fresh user. I opened Outlook 2013 for the first time and tried to add my Hotmail account with the same results: It keeps asking for the password and cannot connect to setup. Mind you, I can still connect to my Hotmail account by logging in to Outlook.com, my phone, my PC at work with Office 365--pretty much anywhere not using 2013. Now, I also have a @Live.com account from Microsoft, and that still works under 2013. I'm not sure why they decided to block the combo of Hotmail and Outlook 2013 all of a sudden, but I would guess this is happening to every user of both.

Do you have all office 20-13 updates installed?

Set these registry keys and see if it helps -

HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\
REG_DWORD: EnableADAL
Value 1

HKCU\SOFTWARE\Microsoft\Office\15.0\Common\Identity\
REG_DWORD: Version
Value 1

Thank you Diane. I think my Hotmail has been offline for about 3 weeks now, and your suggestion did the trick! The second registry key for Version was already set, but the first one did not exist. I added it in:

Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Identity
REG_DWORD: EnableADAL
Value 1

The second I opened Outlook, it was working again! Unfortunately, it looks like a ton of SPAM instantly began coming in as well. I think this may be stuff I deleted via other clients (phone, browser, work), or that had been automatically filtered out already while Outlook 2013 was not working. The SPAM only covered the dates while Outlook was not working for my Hotmail, and no further back than that. It seems to have stopped now.

Again, thank you very much for your help. I was about ready to give up and install a copy of Office from my work--but that would eventually expire if I change jobs, so I am glad to keep this one. Have a great day!
