PC Win: Err Msg: Some Entries Could Not be Added to the Group

CAUSE

When you add one or more users to a Personal Group, the entries will automatically be added to the PAB simultaneously. If a discrepancy exists between the account information being added and the current entry in the PAB, the above error will occur.

When an entry is created in the PAB in Microsoft Mail for Windows, the account information is added to the PAB according to content of the current address lists on the postoffice. If the account is deleted and recreated (using the same Mailbox name, etc.) on the postoffice by the Mail Administrator, the account data becomes obsolete for the current reference contained within the PAB, as the mailbag ID has changed.

This condition may also result if there is a discrepancy in the hexid between the Postoffice Address Lists (POLs) and the ACCESS*.GLB files.
