[horde] Outlook 2015 and ActiveSync

[Volker Then]

Hi guys,

did anyone of you manage to make Outlook 2016 work with Horde  
ActiveSync? It countlessly asks for username and password, there is no  
real manual setup. If I try username at my-horde-domain.com it is not  
working too. We don't use full email addresses as login, just an  
old-school username (which has mostly nothing to do with the email  
addresses associated to the account).

I tried "Exchange", I tried "Outlook.com" and even "Office365". No  
sucecss at all. Autodiscover for said domain is set up, and works  
properly in Outlook 2013. With Outlook 2016 I only see 401s and 200s  
in apache's logfile, when Outlook tries to get the autosdiscover file,  
but it never downloads the xml file.

Is - at the end - activesync functionality removed from Outlook 2016  
or what am I missing? But old accounts, which OL 2016 took over from  
2013 after the "upgrade", are still working.

Some of our clients are switching now to OL 2016, and I am kinda lost  
with that piece of ****. ;-)

Any help is appreciated, thanks in advance
