Remove-MailboxFolderPermission -Identity user@mycompany:\calendar -user myuser@mycompany.com

My Notes on setting password to never expire for a user:

Find users PasswordNeverExpires status:

Get-MSOLUser -MaxResults 2000 | Select PasswordNeverExpires | export-csv c:\result.txt

Start Microsoft Online Services Module for Power Shell (download from web if not arelady installed). “Run As” Admin. Type the following:

Connect-MsolService

Check the password policy for that user:
Get-MSOLUser -UserPrincipalName user@domain.com | Select PasswordNeverExpires
Substitute user@domain.com by the username that you want to change password policy for.

Change it to never expires:
Set-MsolUser -UserPrincipalName user@domain.com -PasswordNeverExpires $true
Substitute user@domain.com by the username that you want to change password policy for.
