Changing -like 'uu-lillebaelt.dk' to -like 'uuoresund.dk' gives trouble

Question

I have two near-identical Powershell scripts.

The only difference between the two is 2 places where uu-lillebaelt has been changed to uuoresund. When I run the script with -like 'uuoresund', I get a bunch of errors saying: You cannot call a method on a null-valued expression And this is happening when calling:

$size.IndexOf

$size.Substring

I have made sure, that size is not actually null, so that is not the problem. I feel that it must be something about the -like operator I do not understand.

What's the type of $size when you encounter those errors? Print all mailboxes with their size to get a better view of those objects. In any case, If I may suggest a solution:

$totalSize = Get-Mailbox -Filter {WindowsEmailAddress -like "*$uucenter*"} | 
Get-MailboxStatistics | Foreach-Object {$_.TotalItemSize.Value} | 
Measure-Object -Sum | Foreach-Object {$_.Sum}

The type of $size is Microsoft.Exchange.Data.Unlimited An example could be: 210MB (210000000 bytes) And this works correctly on the email domains uu-lillebaelt and uu-centersyd for. Only uuoresund gives trouble – Nicholas Magnussen Apr 17 '13 at 13:27
I will try it, first thing tomorrow, busy with a meeting rest of the day ;-) – Nicholas Magnussen Apr 17 '13 at 13:34
Using your example, I get no errors, but the in the resulting xml, totalSize is 0 – Nicholas Magnussen Apr 18 '13 at 06:17
Do you get any result with : Get-Mailbox -Filter {WindowsEmailAddress -like "*$uucenter*"} | Get-MailboxStatistics | Foreach-Object {$_.TotalItemSize.Value} – Shay Levy Apr 18 '13 at 06:31
Found the problem, there was a pesky DiscoverySearchMailbox that is probably empty or return a different format :) – Nicholas Magnussen Apr 18 '13 at 06:36

I found the problem. The Get-Mailbox on the domain also returned a DiscoverySearchMailbox that must be empty, or atleast return something that is not in a format. So to fix that, I just added a -notlike to get rid of that :)

Well, good thing it happened, otherwise I probably wouldn't have caught it.
