An employee left, and I disabled her account on SBS. I then discovered that another employee was still using the departed employee's calender as a shared calender, and needed its contents.
I restarted the departed employee's account, but when she tries to contact the calender, she gets an error message that exchange server is unavailable. When I try to retrieve the calender from my account, I get a message that the information store cannot be opened. I have restarted the Information Store on the server, but it hasn't solved the problem.
I don't have the departed employee's password; if necessary I could try to contact her and retrieve it.
