name changed to object ID in teams

Teresa Porter Ward 0 Reputation points

The name changed to object ID for a few employees. We have not done anything different. I understand that this is a known issue but what is the long term solution? If we remove the SIP like some Microsoft employees has suggested in other chats, doesn't this take away their voicemail to the user's mailbox? I have not seen a permanent solution to this problem yet. We have tried to clear cache and cookies on a few computers but this does not fix the issue.

thank you,
