Need help resolving error when managing mailbox folder rights for users in different subdomains in Exchange 2016
We have trouble adding rights to the calendar folder of one user to another user who is on another subdomain.
We run Exchange 2016 (Version 15.1 (Build 1466.3) and have a main domain we will call domain.local and 5 subdomains. Exchange server is in domain.local.
User1 is in subdomain A.domain.local and has email address email@example.com
User2 is in subdomain B.domain.local and has email address firstname.lastname@example.org
We ran the following command to add LimitedDetails rights to B.domain.local\user2 on A.Domain.local user2’s calendar:
Add-MailboxFolderPermission -Identity A.domain.local\user1:\calendar -User email@example.com -AccessRights LimitedDetails
We get the following error:
The user "FirstName Lastname firstname.lastname@example.org" was found in Active Directory but isn't valid to use for permissions. Try an SMTP address instead.
+ CategoryInfo : NotSpecified: (:) [Add-MailboxFolderPermission], InvalidInternalUserIdException
+ FullyQualifiedErrorId : [Server=XXXXXX,RequestId=XXXXXXX,TimeStamp=01.02.2019 10:31:07] [FailureCategory=Cmdlet-InvalidInternalUserIdException]XXXXXX,Microsoft.Exchange.Management.StoreTask
+ PSComputerName : exc01.domain.com
Can you please help us solve this problem?
Thanks in advance for your help.
