I have a shared folder, that myself and a few other users have Full delegated access from ECP.  I've also ran PS commands to make myself and these users 'owners' and I've ran PS commands to make sure the full access in inherited to all subfolders.

However, when any of us try to open the folder we get this error:

Is there a possibility the Mailbox is corrupt?  Is there some sort of maintenance I can run against this mailbox?  Or am I just missing something?  (I've set up plenty of other shared mailboxes and have not had an issue until now)

Try it from OWA first, Outlook can be picky at times.

So I checked with the user I originally created it for (who could open it at one point) and she is now getting the same error, event hough she was once able to open it.  Is there some kind of maintenance that can be ran to fix issues like this?  (I came from Lotus Domino, if there was database issue's there we had a few built-in tools that would repair the database)

Hi,

According to your description, I understand that failed open shared folder with error Cannot expand the folder. The set of folders cannot be opened. Microsoft Exchange cannot be available. Either there are network problems or the Exchange server is down of maintenance.
If I misunderstand your concern, please do not hesitate to let me know.

Please try login OWA with this mailbox which share this folder to others.
If available, please run below command in EMS to double check the correct permission configuration:
Get-MailboxFolderPermission Identity alias:\ | FL Identity,FolderName,User,AccessRights
Get-MailboxFolderPermission Identity alias:\shared folder | FL Identity,FolderName,User,AccessRights

If it failed, please run Get-Mailbox identity | FL to check the availability of problematic account.

Thanks

Is there a username and password associated with a shared mailbox?  how do I log into OWA with a shared mailbox? 

I've used ECP to give "Full Access Delegation" to certain users.  I've also ran the following commands against the mailbox to make sure the access is there:

get-mailboxpermission:

show's all the users who need it have "Full Access" rights

Add-MailboxPermission - Identity "SharedMailboxinQuestion" -User USER -AccessRights FullAccess - InheritanceType All

I've used my PropagatePermissions PS script to propagate owner access to all subfolders of the mailbox... 

all to no avail.

Here's the Get-Mailbox identity | FL (with my domain and serer info removed)

[PS] C:\>

Go to OWA, click on the user picture, select Open another mailbox from the menu. If the permissions are correctly applied, you should be able to see the shared mailbox opened in a new tab.

Works Fine in OWA, try agian in Outlook, and get the error.

Hi,

As you mentioned, please try to re-configure a new Outlook profile for testing.
Besides, try to new a mailbox and assign full access permission to another account for testing.

Thanks

I have a few shared mailboxes that all work with the proper access.  This one specifically does not, is the thinking that this mailbox is potentially corrupt?  Is there a way to repair it?

Try some simple things first to see if it helps before you start going anywhere else. First i would try to recreate the outlook profile as Allen Wang mentioned in the previous post, that usually fixes this error. If you continue to recieve the error after you re-create the profile, try signing into the PC as another user that has access to this shared folder and see if it works for that user.

Let us know what you find

This happens from Multiple PC's and multiple users, I've basically given up on it, going to delete the mailbox and start over.
