Unable to login to Lync from Blackberry Device

Problem:

Recently i faced this issue, where the error says "Someone is connected to the account from another computer"


Verified the article here, but it didn't solve the issue, as we are already running on Blackberry Enterprise Server 5.0 SP3 MR8.

It is a known issue with Blackberry Enterprise Server.

Resolution:

Once i have restarted the Blackberry Collaboration Service the issue got fixed and user is able to login to Lync from blackberry device.

To fix the issue permanently in your environment, you need to upgrade to BES 5.0 SP4
