Validations for MS Exchange installations

When configuring Condeco meeting room screens with an Exchange implementation, we recommend the following checks to ensure a successful integration.

Validate IP Allowlist

Check Domain allowlist for a list of qualified domains that must be allowed.

Validate authorization type

1. Sign in to the Condeco Device Hub.
2. Click Calendar Settings in the left icon bar.
3. For Authentication, select as appropriate for your Exchange environment:
   1. Microsoft 365 connection: select OAuth.
   2. On-premise Exchange installation: select either Basic/Negotiate or NTLM.
      

!End-of-life notification for Basic Authentication: Microsoft announced support for basic authentication will be discontinued in October 2022. See End-of-life for Basic Authentication for more information.

Validate subscriptions

• On Exchange, check the EWSMaxSubscriptions and Max concurrent connection limit.
• When using Impersonation, check the service account has a separate budget for the following policy parameters:
  • EWSMaxSubscriptions
  • Max concurrent connection limit.
• Refer to EWS throttling in Exchange from Microsoft: https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/ews-throttling-in-exchange
• Check availability of Condeco screen licenses.
