Cisco WebEx: End of Support for BlackBerry
You are receiving this announcement as the currently primary account contact for your company's Cisco WebEx meeting services. Please distribute this announcement within your organization as needed to ensure changes are completed in advance of the deadline.
Due to the decline of BlackBerry’s market share to less than one percent, Cisco has announced the end-of-support and sales of the WebEx Meetings for BlackBerry app, effective January 4, 2017. This includes BlackBerry 10 OS.
By January 4, 2017 Cisco will:
* Remove their app from BlackBerry World and other distribution spaces
* Discontinue technical support and help page support
* Allow existing BlackBerry app users to access WebEx meetings until the end-of-use date
On April 4, 2017, Cisco will completely disable BlackBerry access to WebEx meetings. We recommend users switch to Android or iOS platform to continue using WebEx from a mobile device prior to April 4, 2017.
Thank you for your continued business,
Your West Unified Communications Services Team
