Today (9/16) Apple released iOS 9 for iPhone/iPad devices which introduce a list of new features and enhancements around security as well.
Following users feedback, a sign-in issue was discovered with iOS 9 and Lync 2013 Mobile clients which effect users that have different settings for their region and language one the iOS device, meaning that heir region settings is set to a different language then the iOS language.
For those who have different settings, the following error message would appear:
- Another issue that I discovered (thanks to CB from the comments) is that entering a meeting invite from the Calendar app on the iOS device won’t launch the Lync client anymore.
Update: Microsoft released an update for Lync Server in order to solve the problem
The current workaround for now is to change the iOS language to the match the region settings (or vice-versa) until Microsoft will address the issues with upcoming update or with the next SfB Mobile client version.
