Event ID: 9551 Source: MSExchangeISPublic
An error occurred while upgrading the ACL on folder <folder> located on database First Storage Group\Public Folder Store(<ExchangeServerName>). The Information Store was unable to convert the security for /O=OrganizationName/OU=ou=AdminGroup/CN=Recipients/CN=Alias into a Windows 2000 Security Identifier. It is possible that this is caused by latency in the Active Directory Service, if so, wait until the user record is replicated to the Active Directory and attempt to access the folder (it will be upgraded in place). If the specified object does NOT get replicated to the Active Directory, use the Microsoft Exchange System Manager or the Exchange Client to update the ACL on the folder manually. The access rights in the ACE for this DN were 0x41b.

As per Microsoft: " This event may be caused by the Information Store's inability to match an ACL entry with an Active Directory object". See ME324354, ME328880, ME277906, and ME839862 to resolve this problem.
We had this problem and after "Ignore Zombie Users" didnít seem to have the desired effect. Therefore we went with ME318549 which worked great. We also felt much more in control with this one. Probably not so good if you have a lot of different users showing this errors but ours were the same few over many folders. See EventID 9551 from source MSExchangeIS Public Store for more details.
