We have several Mac computers in our office running Mountain Lion and Outlook 2011.  Outlook keeps asking for the Exchange 365 password.  We've tried reinstalling Outlook and rebuilding the 365 profile and the problem keeps happening.  We are about to give up on Outlook and just use Apple Mail.  Any ideas what is going on here?

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!

I have been fighting this issue over the last few weeks for a client and I am out of idea on how to fix this.

First, some background on this client:
* they have ~50 users, all using Mac computers on a pure Mac network
* the shared calendar is from a local exchange server on the network using "user name and password" authentication. 
* the directory service logs in with their Exchange account
* there are no delegates
* there are no digital certificates used
* there are no local accounts.  All users log in via a network login.
* only one user is experiencing this error
* I have rebuilt the users Outlook database multiple times.  Doing so will correct the issue for a day, then the shared calendar disappears again.
* I have reinstalled OS X from a USB thumb drive.  This had no effect.
* I have removed and reinstalled MS Office 2011 for Mac. No effect.
* I have not erased and recreated the users network account nor have I recreated the Exchange account yet (this is my last resort)

Basically the user states that only their calendar is affected.  Their e-mails both sending and receiving work fine, even after the calendar disappears.  They state that they will be using Outlook, leave it open and use a different program (of which they have nothing different installed from their co-workers) or just be creating/reading e-mails and when they check their calendar, the company/shared calendar has vanished.  

Rebuilding the Outlook Database on the default ID will NOT correct this issue.  Finding an older "backup" ID, setting that to default and then rebuilding it allows the user to see their calendar and the Office Reminder window.

I am at a loss here.  Any help is greatly appreciated.
