Humm, so I tried to create a public folder store to on a server and got:
Summary: 2 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:01
New PUB01-PUB03
Failed
Error:
Active Directory operation failed on dc00003.mydom.local. This error is not retriable. Additional information: Access is denied.
Active directory response: 00000005: SecErr: DSID-03151E04, problem 4003 (INSUFF_ACCESS_RIGHTS), data 0
The user has insufficient access rights.
Exchange Management Shell command attempted:
new-publicfolderdatabase -StorageGroup ‘CN=SG02-PUB03,CN=InformationStore,CN=PUB03,CN=Servers,CN=Exchange Administrative Group (FYDIBOHF23SPDLT),CN=Administrative Groups,CN=BarWealth,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=gbl,DC=barwealth,DC=net’ -Name ‘PUB01-PUB03’ -EdbFilePath ‘F:SG02SG02-DBPUB01-PUB03.edb’

Turns out that if you delegate a group as server administrator they get an explicit deny on the server object for Create and Delete Public Information Store Objects. Suppose it does make sense as a Public Folder is an org wide thing .. but hey, every day is a school day
