How to create the service account for Pronestor Display and Exchange integration

Pronestor Display is integrated with your Exchange environment so that your meetings are shown on the tablets. This is done with a service account that has the right application impersonation in Exchange.

We don't directly support this, as it is done in Exchange and not in Pronestor, but we have gathered some knowledge and frequently asked questions to help you set it up, as well as some links to guides on the internet.

What does the service account need?

For Pronestor Display, the service account needs to have application impersonation rights on all meeting rooms connected to Pronestor Display.

The Exchange service account must have a mailbox and the primary email address for that account must be the original one and not an alias.

Please note Setting of permissions on Exchange can have some latency before the permissions are set and available. Please allow up to 30 min. for Exchange to have the permissions committed.
Please ensure that you set the password for the Service account never to expire. If that isn't possible, then it is the responsibility of the customer to ensure that the password is always updated in Exchange and in Pronestor before it expires.

How to check whether the service account has the correct access

You can check whether the service account has the correct access by running a script in powershell. This has to be done on your Exchange server.

The script:

Get-ManagementRoleAssignment -roleassignee "" -role applicationimpersonation

The results of the script. The "" has the application impersonation rights. The "" is a regular employee without application impersonation rights. If your account has application impersonation, the response of the script will show you the role applicationimpersonation.
