I'm setting up Good ent user and I want to set calendar processing true for all the mailboxes

When I run

Get-Mailbox | set-CalendarProcessing - ProcessExternalMeetingMessages   -True

it gives the errors that this can only be applied to Room Maikboxes - which make sense. So How Do I implement it for regualr mailboxes? Do I need to assign a policy if so then how?

Thanks

Hi, may be this help you.

Working with Calendar Permissions in Bulk on Exchange 2010 

What you can do is convert the mailbox to Room, set it, then convert back to user mailbox. This will preserve the settings that can only be configured for a room mailbox, such as AutoAccept or ProcessExternalMeetingMessages. I'm pretty sure that's not supported by Microsoft though, so use at your own risk :)

Hi,

What the error pops up? Please post the error to us for troubleshoot.

And run the following command against different mailbox type to check this issue.

Set-CalendarProcessing Identity UserName -ProcessExternalMeetingMessages $True

Please let me know the results.

Best Regards.

Set-CalendarProcessing Identity UserName -ProcessExternalMeetingMessages $True

this works for a single usermailbox but It does not work for 6000 mailboxes

Get-mailbox | Set-CalendarProcessing Identity UserName -ProcessExternalMeetingMessages $True it throws the error which means this can only be run against the room mailbox.

ProcessExternalMeetingMessages can only be enabled on resource mailboxes.
