out of office dosent work

Hi

i was advised to post this here as i have tried a few fixes and none have helped

we have an unusual set-up in that our users log onto windows using a normal account and have a mail account setup. however, they also have a second account with second mail account that is set up as a separate mail profile. on the first account, when the users open outlook, it prompts them as to whether they want to use the first or second email account. the credentials are passed then they can open there second mailbox under their first account

here is the issue

when the users try opening the second account, they can do everything but use out of office

the error says the exchange server is unavailable however this isn't correct as the user can till see send and receive emails

any help on this would be greatly appreciated

thanks very much
