Get-Mailbox filter question

[petben]

Hi, a simple Q:

 

I can list all mailboxes starting with 22xxxxx or 21xxxxxxxx with this -like filter:

Get-Mailbox -ResultSize Unlimited | where-object { $_.Name -like "22*" -or $_.Name -like "21*"}

 

 

but to get the opposite, excluding all mailboxes containing 22xxxxx or 21xxxxxxxx I thought just to use -notlike, but it returns all the mailboxes.

Get-Mailbox -ResultSize Unlimited | where-object { $_.Name -notlike "22*" -or $_.Name -notlike "21*"}

 

 

Any advice would be great.

 

Thanks

Its because you're using "or". "22*" are notlike 21 so are included, and "21*" and notlike 22 so are included. You need parentheses.;

 

Get-Mailbox -ResultSize Unlimited | Where-Object { -not ($_.Name -like "22*" -or $_.Name -like "21*") }

Not wishing to put EduGeek out of business, but I literally copied your post and pasted it in to chatgpt. I can take no real credit.
