Issue Status : RESOLVED
Issue Description : Some admins may be unable to create or modify inbound connectors via the Exchange admin center (EAC).
More Info : While Microsoft is focused on remediation, admins may be able to create or modify inbound connectors using PowerShell as a workaround.
Scope of impact : Impact is specific to some admins who are served through the affected infrastructure.
Final Update : 06/09/2022 13:55:00 PM – Microsoft confirmed with affected users that their fix deployment has successfully remediated impact.
Root cause : A recent service update intending to change the requirements needed to create or modify inbound connectors introduced a misconfiguration between the Admin API and the EAC user interface (UI), which was inhibiting some admins from creating or modifying inbound connectors.
Next steps : Microsoft are reviewing their update procedures and the introduced misconfiguration between the Admin API and the EAC UI to understand why impact was missed during the update testing phase and to help identify similar issues during the development and validation processes.
