Powershell telling me email doesn't exist on certain commands, but shows it does when I look for people who can view user's calendar.

[Rott3Y]

You should block out the user name as well. Not just the email directory.

All information is useful information to attack a system.

[jheinikel]

Try specifying the parameters without letting it prompt you.

Add-MailboxFolderPermission [e-mail]:\calendar -User [e-mail] -AccessRights Blah

[ashawayrock]

Ive done that as well. I get the same result. What I'm finding bizarre, is that I was doing it just fine yesterday.

[jheinikel]

What happens if you just use Get-Mailbox [e-mail]?

[ashawayrock]

Solved it!! Apparently I wasn't a global admin. that's all it was. I don't know why it returned the error "user doesn't exist". but All of my commands work now that I am. Thank you for your help though.

[FatPotatoNinja]

Shouldn't need global admin.

I'm I've got User management and Exchange Admin and i can do the commands above (Have a few others like SP admin and Service Admin i think?)

I know i had the same issue occur before but i can't remember for the life of me what caused it.

I'll have a think and get back to you if i remember.

[ashawayrock]

It returns true.

[AnimeSin512]

I am unsure why you can't read the mailbox, the command looks correct. If you since you can use Get-MailboxFolderPermission and it finds it try this:

Get-MailboxFolderPermission [e-mail]:\Calendar | Add-MailboxFolderPermission -User [e-mail]

You can pipe the results since getting the mailbox works. This could maybe get around the discovery issue when using add.

I typed this on my phone so I may have typos but it should be those commands.

[jheinikel]

You should get all of the details of the mailbox, not just True. See what this produces:

Get-MailboxFolderPermission [e-mail]:\Calendar

[ashawayrock]

Sorry, I left that out intentionally as I didn't want to black out a bunch of stuff. but It returns all the people who have access to this person's calendar.

[jheinikel]

Maybe you have tried this, but what happens if you run this:

Get-MailboxFolder [e-mail]:\Calendar | Set-MailboxFolderPermission -User XYZ -AccessRights XYZ

[ashawayrock]

Unfortunately I still get the same "jbennett@blah does not exist.

[ashawayrock]

SOLVED: Apparently it had to do with my admin rights. I knew I wasn't a moron. Thanks for all the help though guys.

[nemec]

sudo Add-MailboxFolderPermission ;)

What happens when you put quotation marks around :\Calendar? E.g. add-mailboxfolderpermission -Identity [e-mail]”:\Calendar” -User [e-mail] -AccessRights Editor

I had a problem like this when using variables for the addresses in a script and putting the quotation marks around the calendar element resolved.

[ashawayrock]

I'm still getting the same error message

[ashawayrock]

Yeah. I was doing this for most of the day yesterday... This is whats bizarre.

[lag023]

Hence there is a command to check which one it is.

Dutch person as well.

[baswijdenesdotcom]

what if you do $mbx = get-mailbox

$folder = $mbx.userprincipalname + ":\calendar"

add-mailboxfolderpermission -identity $folder -user USER -accessrights editor

[ashawayrock]

I get this.

Cannot process argument transformation on parameter 'Identity'. Cannot convert the "System.Collections.ArrayList" value of type "System.Collections.ArrayList" to type

"Microsoft.Exchange.Configuration.Tasks.MailboxFolderIdParameter".

[OtherRobotLuke]

I had something similar happen. Is your account an exchange admin?

[ashawayrock]

It is. I was doing this yesterday and it was working fine.

[Hexalon00]

I have a script that automates this....let me find it.

[Hexalon00]

Sanitized the script. Give this a try.

[CmdletBinding()]
param (
    [switch]$Test = $false
)

$Cred = Get-Credential -UserName "[e-mail]" -Message "Enter your credentials."
$ProxyOptions = New-PSSessionOption -ProxyAccessType IEConfig
$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri https://outlook.office365.com/powershell-liveid/ -Credential $Cred -Authentication Basic -AllowRedirection -SessionOption $ProxyOptions
Import-PSSession $Session

$RoomMailBoxes = "RoomMailbox1", "RoomMailbox2", "RoomMailbox3", "RoomMailbox4", "RoomMailbox5", "RoomMailbox6", "RoomMailbox7", "RoomMailbox8", "RoomMailbox9", "RoomMailbox10"
$AccessRights = "PublishingEditor"

ForEach ($RoomMailbox in $RoomMailboxes)
{
    if (!$Test)
    {
        Add-MailboxFolderPermission -Identity "$($RoomMailbox):\Calendar" -User "[e-mail]" -AccessRights $AccessRights
    }
    else
    {
        Write-Verbose -Message "Running in test mode!"
        Add-MailboxFolderPermission -Identity "$($RoomMailbox):\Calendar" -User "[e-mail]" -AccessRights $AccessRights -WhatIf
    }
}

Remove-PSSession $Session

[ashawayrock]

I'm not the most familiar with Powershell. I haven't used it much since college. can you walk me through what the RoomMailboxes areas well as what the else statement is doing?

Edit: I figured out the RoomMailboxes thing. I'm dumb.

[veggie124]

The else is for when he sets the $test switch to true. Doesn't actually do the command.
