Mailbox not listed as "Available" to archive
I have a user that is not seeing the Vault cache in her outlook client. Her toolbar is not showing either. This lead me to the conclusion that her mailbox was not enabled for archiving. I went to the "Enable Vaults for archiving" icon on the top of the EV console, chose list all available mailboxes, and hers is not listed. I ensured i was looking at the correct exchange server. Her account is also not listed in the "available for disable" list.
Her archive under Archives->exchange mailbox, however, is listed and shows as available. I dont think her exchange box is hidden since her info shows up in the global address book (I dont have permisisons to check if its hidden or not).
It may be worth noting that this user worked for my company for a while, was terminated, and was re-hired recently.
Any help would be greatly appreciated.
