Recovery of Calendar in Mailbox failed

Hi there,

i got the following problem:

when i try to restore a Calendar in a Usermailbox, the Job fails due to unavailable Space.

I know that BE needs to restore the whole Mailboxdatabase to a local HDD to recover the Items via GRT.

In my opinion it was not that hard to restore single items in the past.

Is there another way to get the things back?

The main problem is that the backup Server does not own enough space to recover the whole database.

Any soloution would be great!

Thanks a lot.

Cheers,

Sebastian
