UPDATE It turns out this was a false alarm on the part of an end user, but there are some helpful posts and suggestions if this actually occurred. UPDATE

I have a user that accesses their Exchange mailbox using OWA exclusively.
They claim that their Contacts have mysteriously been deleted. They say they had 50-60 Contacts.
When I go into their account, there are only 2 Contacts - they say they just added those.
No Contacts are showing up in the Deleted Items folder, nor in any other folder listed in OWA. There are no subfolders within the Contacts folder.
In OWA "Options"/"Deleted Items", there are no Contacts in the "Recover Deleted Items" list - only old emails and a few Calendar items.
If I create a new message and start typing a name in the "To:" box, several Contacts appear in a drop down list. I can also start typing names in the search box at the top of the OWA window and names appear. I don't know where these names are coming from. They are not in the Default Global Address List.
I also wonder if there's a way to check if Contacts have been deleted. The user thinks it started last Friday.
Thanks for any help, Dan
Each folder maintains a list of items that were <SHIFT>-<DEL> deleted in that folder. OWA only shows you those items that were deleted when the "Deleted Items" folder was emptied.
If you're not finding the items using "Recover Deleted Items" from OWA you might try using Outlook to open the user's mailbox. The procedure varies per the version of Outlook, but, essentially, you're talking about setting the "DumpsterAlwaysOn" registry value (see http://support.microsoft.com/?kbid=246153), opening up the user's mailbox in Outlook, and attempting to recover deleted items. (See http://hosting.intermedia.net/support/kb/default.asp?id=728 for some background on recovering deleted items in various Outlook versions.)
If you're not finding the items that way then you're going to be stuck restoring a backup into a recovery storage group and getting the items out that way. The procedure will vary depending on the backup software you're using, but you can get a bird's eye view of the procedure here: http://technet.microsoft.com/en-us/library/aa997694(EXCHG.80).aspx
What you're seeing is the autocomplete feature of OWA. Autocomplete is essentially a cache of email addresses that the user has typed into the To: field at some point. The autocomplete entries are not directly related to the Contacts in the sense that the existence of an autocomplete entry doesn't confirm the existence of a Contact and the lack of an autocomplete entry doesn't confirm the non-existence of a Contact. The autocomplete cache may have entries that correspond to the contacts but that's pretty much where the relation ends.
