Hard Match when Source Anchor Attribute = sAMAccountName got changed in AD

Hi rahul2275,

1. Check PrincipleName, Mail, ProxyAddress and sAMAccount in attribute editor (AD) for that user.

2. Run the CMDLET below DC PowerShell/ Change the path

ldifde -f C:\Users\username\Desktop\export.txt -r "(Userprincipalname=*)" -l "objectGuid, userPrincipalName,sAMAcocountName"

3. Get the Object Guid for the target user from exported file.

Run the PS in ADConnect server as Admin

Connect-MSOLService

Run the CMDLET below:

Set-MsolUser -UserPrincipalName username -ImmutableId ObjectGUID_VALUE_From_Step2

4. Force Initial

Sync.Start-ADSyncSyncCycle -PolicyType Initial

Hope this helps!
