I have given myself full access to 3 mailboxes, but when I try to open these using either open other mailbox in OWA or by adding the mailbox to my Outlook profile, it does not work. When I log on as these mailboxes there is no issue, everything is as it should be.

I initially used the ECP console to give myself access, but there is a known problem where this sometimes results in what I am seeing so I removed this access and logged onto one of the Exchange servers and used the Exchange Management shell to add myself using

Add-MailboxPermission -Identity JDoe -User 'testuser22' -AccessRights FullAccess -InheritanceType All -AutoMapping $false

Same result. I then moved the mailboxes to a different database as I have seen this resolve issues previously, no joy.

This is a concern as we have a process where anybody leaving the organization for any reason has their mailbox linked to their manager so they can deal with any open issues and incoming mail for a period of time, this is clearly not going to be possible if I am unable to give access to the manager.

Looking at the Delegates settings for these accounts I can clearly see I am listed as having full access yet it is not allowing me to open them unless I log in as the account.

Any suggestions on how to fix this?

To further confuse matters, if I go into Outlook and use File > Open and try to open one of these mailboxes, it shows me the contents of the inbox, but adding the account still gives no access, I get an error saying Cannot expand the folder

Does this occur only for certain mailboxes, or all of them? In addition, do you have any rights management solutions (eg. MS RMS) handling messages within the mailboxes?

This one is a long shot but - are the users members of any protected groups (domain administrators for example) ? I know this usually causes read/write permissions added to their accounts to be stripped away, but I'm not sure if it applies to exchange.. worth a check though.

Cheers,

Thanks Max,

No, there is nothing like RMS in use for any of our mailboxes.

One of the accounts in question is a simple inbound mailbox used for recruitment and is no AD groups apart from domain users, the others are accounts formerly used by people who have now left and had all group membership removed.

Neither of the user accounts were domain or Exchange admins before they left.

Whats the exact error you get when you try to open the mailbox through outlook and Owa (and do these messages differ) ?

In Outlook I get Cannot expand the folder

In OWA I get an error page saying (this is the exact text from the page, including the sad face emoticon):

Hi ,

Please run the below mentioned command for anyone of the problematic mailbox and try to open it on owa.

Set-Mailbox "name" -ApplyMandatoryProperties

Ran the command on one of the mailboxes, I got the response:

WARNING: The command completed successfully but no settings of 'domain/OU/mailbox' have been
 modified.

I am still unable to open the mailbox

The same happens for the other mailboxes I have encountered the issue on

Hi,

From your description, when you move these problematic mailboxes to another database, the issue is solved. The issue should be related to corrupted mailboxes, it is recommended to repair these problematic mailboxes and check the result.

Hope this can be helpful to you.

Please try to move the mailbox to a different DB with option -baditemlimit and they give it a try.
