immutableID就是objectID[mS-DS-ConsistencyGuid]的base64编码

# 问题是，一旦我将用户移动到本地AD中未同步的测试OU，然后强制同步，我仍然无法设置immutableID并且收到错误：
Set-MsolUser：Uniqueness violation。Property: SourceAnchor.
At line:1 char:1

# 这是因为当o365看到该帐户不再来自AD时，它将其移至已删除的用户。我找到了用户：
Get-MsolUser -ReturnDeletedUsers | fl 
# 果然，immutableID与我试图设置的匹配。
# 我用以下方法清除了用户：
Remove-MsolUser -UserPrincipalName username@theirdomain.onmicrosoft.com -RemoveFromRecycleBin 
# 然后OK
Set-MsolUser -UserPrincipalName user@domain.com -ImmutableId $ImmutableID

如果执行set-msoluser报错，可以试试下面的方法。参考链接https://stackoverflow.com/questions/42805114/how-to-set-immutable-id-of-an-msoluser-to-null-value-using-powershell

Move the federated domain onto a managed domain:
Set-MsolUserPrincipalName -UserPrincipalName edwardlt501edwar@KT2.kb.co.in -NewUserPrincipalName edwardlt501edwar@<managed domain, usually something.onmicrosoft.com>

Set immutableid to null:
Set-MsolUser -UserPrincipalName gw17edwardlt501edwar@<managed domain> -ImmutableId "$null"

Then wait for some time and assign a new immutable id:
set-msolUser -userprincipalname gw17edwardlt501edwar@<managed domain> -immutableID f33fc1d2-73bd-4957-995f-37c83d349ef3

Move back to federated domain:
Set-MsolUserPrincipalName -NewUserPrincipalName edwardlt501edwar@KT2.kb.co.in-UserPrincipalName edwardlt501edwar@<managed domain>

See the new immutable ID:
Get-MsolUser -UserPrincipalName edwardlt501edwar@KT2.kb.co.in | select ImmutableId
