Exchange 2010 public Folder #554 .2.0 AD-user not found

We have a migrated system, Exchange 2003 -> 2010. Now, years later we recognized a problem sending mails to mail-activated public Folders (#554 5.2.0 STOREDRV.Deliver.Exception:ObjectNotFoundException...). The old 2003 server does not exist since years.
We have tried the solution from article
In ADSI-Editor the container "CN=Servers" does not exist, maybe somebody tried that solution in the past.
I do not understand the next step in that article, Moving the public folder hierarchy to exchange 2010. can Anybody describe step by step what to do, or help if the problem has another reasen.
Thank you.

Try this option.  Cannot say I have tried it and it may not work if the servers container has been removed but looks low risk if you put ESM on an old PC...

So is the issue with all PF's or just few and does all user face the same issue ?
Also what if you mail-enable a new PF ?

Mail Enabled Public Folder does not receive mails after migrating to Exch2010
I’ve deleted this container, run an update of the public folder hierarchy and that solved my issue – of course I had to add the ‘Contributor’ permission to Anonymous user on that specific public folder

So do you still have the old AG folder as empty ?

I'm sure thats not an option, as I said there is no old Exchange 2003 server yet. It has been deleted long time ago.
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

I did try three different Mail-Activated Public Folders also Mail from inside and outside all with the same error.
I have tried with a new created Folder, too - same error.
What do you mean with "ran an update of the public folder hierarchy..."? - I did restart the complete server and did wait 24 h and tried again - same error.
Permissions are checked and ok, if not I would get a different error message!
Like i wrote yesterday the CN Container of the old server does not exist..
But the "CN=First Administrative Group" still exists, also the newer "CN=Exchange Administrative Group".
Should I remove the old one? Is it safe to delete?
Ralph ScharpingDigital TherapistAuthor Commented:
I have an solution.
The CN="old servername" did not exist, so i did comment before, but the container CN=servers was still there... I'm sorry for misunderstanding the linked solutions...
Thanks for all comments!
