CRM Outlook issues after October 2017 updates

Several complains from clients regarding Outlook CRM client (add-in) that stopped working and does not show (render) accounts, contacts, dashboards in Outlook. At the same time Web browser works ok.


The problem is related to recent security updates for Outlook 2010, 2013, 2016. You can fix it by adding registry to current user:


EnableRoamingFolderHomepages

Polycom VVX debug

I had a case when VVX did not work for hybrid Exchange with Lync onPremises, I spent a lot of time to understand why it is not working until I enabled logging for CURL as DEBIG :)

As always the problem was in SSL Certificates.

Polycom VVX for hybrid Exchange

Polycom FW version 5.5.3 and Exchange hybrid.

From the logs we see that Polycom tries to perform autodiscover, but finally fails and leave EWS not deployed for online users.  I will continue debuging that, but I found a workaround:

login with sip and UPN  as username@domain.com but leaving domain field empty.
Then in settings-applications-exchange server URL you can hardcode:

https://outlook.office365.com/EWS/Exchange.asmx/WSSecurity

and leave autodiscover disabled.

Update: with CURL DEBUG we can see that problem was in SSL certificates of Digicert not being trusted due to limits we left from other tests in Network - TLS - Application profile 6 (select certificates from platform or imported, but we had only one certificte selected). I also imported Digicert root, as for unknown reasons outlook is based on that while rest of MS is Baltimore.
