This is a very odd issue.

On a user using a the GroupWise 2014r2 client on a loaner PC in online mode, the user had address book corruption. The user would type in a last name to address an email message, but a different (incorrect) email address would appear. The user had the PC for less than 24 hours.

But the user would then go to the our Citrix server where we still have the GW8 client, the address book worked correctly.

My co-worker then searched the address for the user name on the loaner laptop and found the corruption and deleted the entry.

My question is I thought all of the address books are kept on the server, not the local PC.

Thanks
