Error when trying to run "Set-MailboxAutoReplyConfiguration"

Question

Trying to create a script that will set the auto-response for all disabled users but I am getting an error on the Set-MailboxAutoReplyConfiguration command.

I have tried it in both Powershell and Exchange Management Shell.

I have tried different variables for the identity and all give the same error.

Running this on the local Exchange Server - Exchange Server 2019 CU14 (2024H1)

Any help would be greatly appreciated.

Set-MailboxAutoReplyConfiguration xxx@abc.com -AutoReplyState Enabled -ExternalAudience All -InternalMessage 'xxx message xxx' -ExternalMessage 'xxx message xxx'

Write-ErrorMessage : |Microsoft.Exchange.Configuration.Tasks.ManagementObjectNotFoundException|The operation couldn't be performed because Identity:"xxx@abc.com" couldn't be found.

Answer 1

Try a get then a set. Example:

Get-MailboxAutoReplyConfiguration <id> | Set-MailboxAutoReplyConfiguration etc...

Answer 2

Damm, got the same error, even with just the Get-MailboxAutoReplyConfiguration command.

Answer 3

Where are you running these commands? They have to be run against where the mailbox is.

It appears you are running against Exchange Online, not on-prem.

Server=SN4PR22MB3221

Where do the mailboxes live?

Answer 4

i have exactly the same issue. Exchange Online... tried get/set, but have the same result "couldn't be found"
