Shared folders do not appear in Outlook 2011 on Mac

Hello,

At my workplace we have some PC computers running outlook 2003, and some Mac computers, running outlook 2011. I am trying to share folders from an outlook 2003 account on PC, and have them visible on the Mac outlook 2011 account.

Ideally I need to be able to open a secondary calendar subfolder, but I am actually unable to open ANY shared folders.

I know the complicated process for sharing subfolders, and have executed this between multiple 2003 PC users, but am thus far unable to do it on a Mac. Here is what have tried:

I have given the 2011 mac user permission as an editor to my calendar, and my mailbox, and had that user try to "open a shared calendar" and "open a shared inbox"

I have made the 2011 mac user a delegate with editor access to my mailbox and calendar, and then had that user add me in "users I am a delegate for" and then try to open my mailbox and calendars.

In both cases I do not get any error messages, but nothing happens - no folders appear, no "shared folders" drop-down appears on the navigation bar. Nothing - I click okay, the window closes and nothing is different.

If I go to send an e-mail on the other user's computer, I can select myself to send the e-mail from, but when I send the e-mail I get a "Unknown error has occured in outlook" -19992 message.

I have tried quiting and reopening outlook on both accounts multiple times.

Thank you in advance for all your help!
