#354 Blocked by conditional access

[Rajamani Muniappan]

I am not sure whether it has to be reported to as a feature request or bug. Please suggest.

I have been using pidgin/sipe for connecting to Skype for Business for long time. It stopped working a couple of days before.

As suggested in this page "https://sourceforge.net/p/sipe/discussion/688534/thread/497bf3fa72/, I have tried to setup User Agent but it did not help.

I am trying to login to my company's (hcl.com) Skype for business account using my client's laptop (staples.com).

Configuration:
Windows 7
Pidgin: 2.13.0
* SIPE: 1.24.0

Could you help?

Thanks in advance!

Other possibilities are that Microsoft has changed what user agent values are accepted or your IT has disabled access for mobile clients.

As you use Windows you of course have the fallback option of using the official SfB client too.
