iOS 11 Compatibility

Does Microsoft expect to have Day 0 compatibility with iOS 11 for the Skype for Business mobile app? Any known issues that enterprises should be aware of as we prepare to announce support for iOS 11...

Hi Korbyn,

Thanks for your reply. Where exactly you made these changes? On which application pool of IIS? I am using Kemp VLM as a reverse proxy for S4B mobile and i have increased the timeout limit on Kemp but not sure where else should i need to do it.....

By the way, even after upgrading the iOS to 11.0.3, the users are still unable to connect S4B.

Regards,

Korbyn

I only had to increase on the reverse proxy servers, IIS ARR in our cases. Kemps are usually at 20 mins, or should have been already, but they're a little more hard core, so you may need to make sure the firmware is up to date on the Kemp's. Could also try bumping to 30 mins. Are there any other firewalls in that path, before or after the Kemp?

I also use IIS Crypto from Nartec as well to clean up the Cipher's and disable SSL 2.0 and 3.0, which may also be a combined effect with increasing the timeout to 1800s or more.

Every time Apple comes up with a new iOS, they find fantastic new ways of mucking up encryption.
