Unable to Set-MailboxFolderPermission

[eeri1540]

Unable to Set-MailboxFolderPermission example@test.fi -user Default -accessrights reviewer. Error message says that "There is no existing permission entry found for user".. We think this is because of Finnish language settings that automatically convert value "Default" to "Oletus" in powershell:

Error on proxy command 'Set-MailboxFolderPermission -User:'Oletus' -AccessRights:'Reviewer' -Identity:'example@test.fi' -Confirm:$False' to server AM6PR01MB4295.eurprd01.prod.exchangelabs.com: Server version 15.20.1856.00

Any ideas?

You might simply have an folder with the default entry deleted, in which case use the Add-MailboxFolderPermission cmdlet instead. The language shouldn't matter, as long as you enclose the string in quotes.

@Vasil Michev Nope. Add-MailboxFolderPermission example@test.fi -user Default -accessrights reviewer, Cmdlet error with following error message: Microsoft.Exchange.Management.StoreTasks.InvalidExternalUserIdException: The user "Oletus" is either not valid SMTP address, or there is no matching information.

Once again "Default" is automatically converted to "Oletus" and not working. Same thing, remove-MailboxFolderPermission.

I also try to use quotes 'Default' and "default" but not helping.

Well, for some reason the culture cmdlets don't seem to work on my machine, but try using Set-Culture first before running the cmdlet. Or just use an English box :)

Ok, Thanks. Issue resolved.

First "Set-Culture -CultureInfo en-us" and then open new powershell session.

$modules = @(Get-ChildItem -Path "$($env:LOCALAPPDATA)\Apps\2.0" -Filter "Microsoft.Exchange.Management.ExoPowershellModule.manifest" -Recurse )

$moduleName =  Join-Path $modules[0].Directory.FullName "Microsoft.Exchange.Management.ExoPowershellModule.dll"

Import-Module -FullyQualifiedName $moduleName -Force

$scriptName =  Join-Path $modules[0].Directory.FullName "CreateExoPSSession.ps1"

. $scriptName

$null = Connect-EXOPSSession

Key here is to open new powershell session else Set-Culture does not work.

Thanks! That helped me!
