I have a user with 32 bit Outlook 2013 running on two separate computers. She connected to Exchange 2010 via https. The two mailboxes aren't syncing. Changes made in one are not reflected in the other. I checked them against OWA and changes made in Outlook are not being synched to OWA. I deleted and recreated the profile on both computers and manually deleted the OST file. Changes made in OWA do propagate to the Outlook clients. When I update the folder a sync error is generated, all of which essentially say:
18:04:39 Synchronizer Version 15.0.4649
18:04:39 Synchronizing Mailbox 'USER
18:04:39 Synchronizing Hierarchy
18:04:40 1 folder(s) updated in online store
18:04:41 Synchronizing local changes in folder 'Inbox'
18:04:41 Uploading to server 'server.domain.local'
18:04:42 1 item(s) changed read-state in online folder
18:04:42 Error...
