We have about 1000 users spread over two BES servers, running BES 4.1.5
On Saturday, we recieved lots of calls saying users couldn't send or recv emails on the handhelds. The error when sending was a red X with the message "all attempts to send have failed"
However, other users were unaffected.
Rebooting the server on Sunday appears to have resolved the issue.
Anyone know how to even begin to troubleshoot what went wrong?
