How to create a service account on MS Exchange 2013 and above

Pre-Requisites

1. Ensure Exchange Web Services (EWS) are enabled on an SSL connection

– Ensure that your Exchange server has a signed SSL certificate from an approved certificate authority.

– Ensure that inbound connections are allowed on any firewall on port 433 to your Exchange server (you can restrict IP access IP ranges listed on this article )

2. Enable Exchange Autodiscover service

3. Enable basic authentication on Exchange server and Autodiscover service.

Create a Service Account

1. Create an Exchange user with a mailbox that will act as the service account.

2. Using Exchange Management Shell, Enable the Active Directory extended permission for ms-Exch-EPI-Impersonation on all Client Access servers.*

Get-ExchangeServer | where {$_IsClientAccessServer -eq $TRUE} | ForEach-Object {Add-ADPermission -Identity $_.distinguishedname -User (Get-User -Identity <EnterExchangeSyncServiceAccountEmailAddress> | select-object).identity -extendedRight ms-Exch-EPI-Impersonation}

3. Enable the Active Directory extended rights for ms-Exch-EPI-May-Impersonate to provide the service account impersonate rights over mailboxes. *

Get-MailboxDatabase | ForEach-Object {Add-ADPermission -Identity $_.distinguishedname -User <EnterExchangeSyncServiceAccountAddress> -ExtendedRights ms-Exch-EPI-May-Impersonate}

4. Configure your service account to impersonate the group of users you wish to connect to timetoreply by creating a management scope that defines the filter grouping the Exchange users.

e.g. If all relevant mailboxes had the Department filterable property set as ‘InsideSales’ replace <RecipientFilter> with Department -eq ‘InsideSales’

New-ManagementScope -Name:<DefineExchangeSyncScopeName> -RecipientRestrictionFilter:{<RecipientFilter>}

5. Create a management role assignment that restricts the service account to impersonate only the users you defined in the management scope above.

New-ManagementRoleAssignment -Name:<DefineExchangeSyncRoleAssignmentName> -Role:ApplicationImpersonation -User:<EnterExchangeSyncServiceAccountAddress> -CustomRecipientWriteScope:<DefineExchangeSyncScopeName>

*Note that if you receive a pipeline error message, wait a few minutes and reenter the command to let your server process the requests.
