I have a deployement i was setting up for a client. In the environment we have provisioned cisco a flex and configured teams as well as exchange hybrid calender connector.
The expressway c is running version X12.5.1 and the calender connecter version 8-11-1.0.7675, management connector version 8.11-1.0.104.
My challenge is the calender connector goes in running state for a while then later turns into running with errors.
The error will be writtern "An error occurred accessing microsoft exchange server. Calender service requests and notifications will not be processed until this is resolved. Detailed info: this includes "https://mail.mydomain/ews/exchange.asmx". The last known error is :"Exchange server unreacheble."
I have tried a continous ping to the exchange replies without showing any network disconnect.
Is there anyone with the same issue who can point me to the possible solution on this.
