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: We’re testing and validating the fix in our internal environment prior to deploying it to the affected infrastructure. We expect to provide deployment timeline by our next scheduled update. <\/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 contained an X500 smtp address assigned to them, which prevented users to delete the contacts from the contact list within Outlook on the web. <\/p>\n
