Latest Message<\/th>\nTitle: Users may be unable to delete a user from the contact list within Outlook on the web<\/p>\n

User impact: Users may be unable to delete a user from the contact list within Outlook on the web.<\/p>\n

Current status: The process to test and validate the fix in our internal environment is taking longer than expected. We anticipate completing this process by the next scheduled update. Once the fix has been successfully validated, we’ll proceed with deployment.<\/p>\n

Scope of impact: Users attempting to remove users from the contact list within Outlook on the web may be impacted.<\/p>\n

Root cause: The Microsoft Entra ID contacts that were removed from active directory contain an X500 smtp address assigned to them, which is preventing users from deleting the contacts from the contact list within Outlook on the web.<\/p>\n
