I'm in the preparation stage of migrating our Public Folders from an on-premises Exchange 2016 CU19 server to Exchange Online. Running the SourceSiceValidation.ps1 script outputs several orphaned MEPFs in our Active Directory, and I get a similar output from the ValidateMailEnabledPublicFolders.ps1. The recommendation is to delete the orphaned MEPFs, but I'm running into an oddity that I just don't feel comfortable deleting. There's a PublicFolder named "Schema" in our MESO OU, and it just feels wrong to delete anything named "Schema" in a database. 

 

Get-ADObject "CN=Schema,CN=Microsoft Exchange System Objects,DC=***,DC=***" | fl


DistinguishedName : CN=Schema,CN=Microsoft Exchange System Objects,DC=***,DC=***
Name              : Schema
ObjectClass       : publicFolder
ObjectGUID        : 9*******-8***-4***-8***-2***********

 

Any advice on how to determine if this object really is safe to remove?

 

Thanks!
