I created a new user in on-premise AD and then set the object GUID value in MS-DS-Consistency-Guid attribute. After that I created a user in Microsoft 365 by running 'New-MsolUser' powershell command along with Immutable ID (After converting GUID value using Convert.ToBase64String(guid.ToByteArray())). The user is successfully created in Microsoft 365 portal. but the Sync status shows as 'In-cloud'. I have run delta sync multiple times, but the status is still not 'Synced from on-premise'. Am I doing something wrong?
Would creating the user with 'New-AzureADUser' help?
Would a full sync help?
Could this is be possible because the Immutable ID attribute is different from 'MS-DS-Consistency-Guid'?
It would be useful if you could list possible reasons and troubleshooting for me to check.
