Shared mailbox not searchable in Outlook

How can I get a shared mailbox searchable from Outlook?
PS... setting cached mode on for those shared mailboxes is not an option:
https://social.technet.microsoft.com/Forums/en-US/9729bba3-8d1e-4a17-b4d5-6e44d7ef1a9e/automapped-mailbox-is-not-searchable?forum=exchangesvrclients
My only work around in the mean time is to add a separate account, which means everyone has owner rights to the inbox in order to search it... there's got to be an easier way to do this... I can't believe that Microsoft wouldn't have thought this far ahead
when developing their new search feature...

Unfortunately as mentioned here
http://community.office365.com/en-us/f/172/t/223771.aspx I believe it's the expected behaviour that if you tell Outlook to search "All Mailboxes" it won't include any additional / shared mailboxes you have configured.
If you click on the search box then in the search tab click Search Tools, followed by Locations to Search, you'll see all of those places that Outlook will include when searching "All Mailboxes", and if your Outlook is the same as mine then that
doesn't include additional mailboxes. In my case it includes my main Exchange account, a POP3 mailbox I have setup and an archive .pst file I have attached, but not the additional mailbox.
I don't know, but I suspect the issue is that Outlook / Windows search is actually searching and indexing the physical Outlook files (eg pst/ost) or at least basing what it indexes on them. Since additional mailboxes don't have their own .ost file they're
not listed, yet a locally attached .pst file is.
You should however be able to search the additional mailbox directly, either by selecting the additional mailbox before typing the search term you're looking for, or by going into Search Tools, selecting Advanced Find, and then in Browse selecting the mailbox
you're interested in.

Outlook 2013 (Only) - Shared Mailbox - Not Syncing

Hi
After searching this forum and many other forums online, I have decided to ask my question here as I cannot find a solution.
We are migrating from Exchange 2003 to Exchange 2010 at the moment. All of a sudden our Outlook 2013 users (All of them) cannot update Shared Mailboxes. When you select that folder it says "Updating this Folder" but nothing is happening. Only happens
with their open Shared Mailbox not with their own Mailbox. I have done the following tests:
Users can open the Shared Mailbox and sync properly using OWA.
Users can open the Shared Mailbox but cannot sync via Outlook 2013.
Users can open and sync the Shared Mailbox via Outlook 2010.
Ran OST repair tool, no luck.
Completely deleted the profile and wiped all the files in the outlook folder and recreated the profile, no luck. (Not syncing straight away.)
Users can sync the Shared Mailbox when they are running outlook in Online mode. (I dont wanna do this coz they want to save their sent emails from a Shared Mailbox into the respective "Sent Item" folder which only works in Cached Mode.
Everything used to work fine and suddenly stopped for everyone. Can you please guide me on how to fix this?
Thanks in advance.
With regards
M
PS
I just realized that my Build Version is "Version 14.1 (Build 218.15)"
I am downloading the Service Pack 3, and it might help?

Hi,
It seems that the issue only happens in Outlook 2013 Cached mode. If you add secondary mailboxes to your profile through the Advanced
tab in the Microsoft Exchange dialog box, please check whether the “Download Shared Folders” is enabled in the Advanced tab.
If it is, the Sync issue occurs may because Outlook 2013 locally caches (in your Outlook data file [.ost]) all folders to which you have access in the secondary mailbox. To resolve it, we can refer to the detailed solution in the following KB:

Hi,
I found this little tick yesterday and did clear it. So now people can still have their own mailbox cached and the rest online. But thank you for the link coz I couldnt find it before and it is good to know that it is a known issue rather than being a misconfiguration
at server level :) I have marked your post as the answer. Thanks again.

Sent items not saved in personal sent items when shared mailbox is open in outlook

hi,
user is using exchange 2010 and the shared mailboxes are in exchange 2003. when user send an email as send as to the shared mailbox the sent items is not saved in her personal sent items. she can look up the sent items on her shared mailboxes sent items.
I tried recreating her profile when the shared mailboxes are not added in the outlook, personal sent items is okay but when the shared mailboxes is added , sent items doesn't go to her personal sent items. Please help. Is it by design?

Hi,
Since Exchange 2003 server is out of support, I still suggest migrating to Exchange 2010 server.
How about this behavior on OWA, if everything going well as expected, it should be an issue on the Outlook client side.
Please try to run Outlook under safe mode to avoid some AVs and add-ins.
Thanks

Shared Mailbox folders missing in Outlook Cached Mode

Since I got no responses to my
original post in section, "Exchange Server 2013 - Sharing and Collaboration: Site Mailboxes and Public Folders" I'll give it a try here...
We have Exchange 2013 Server (Version 15.0 - Build 913.22). I have a shared mailbox for our support team, "Support Center". This mailbox is configured as a "SharedMailbox". Our team members have been given Full Access
either by the Admin Web Interface or by "Add-MailboxPermission -User user1 -AccessRights FullAccess".
I am seeing this issue using Outlook 2013 Pro plus that manually created subfolders either in the root of the mailbox or folders under the Inbox are not visible. These folders are just for organization, like "Work Order Entered" and are not
like contact folders or any other special folders.
We determined if the Outlook client is configured for "Online Mode"/non-cached the folders appear and are accessible, but if your enabled Cached exchange mode the folders disappear and are no longer accessible. I have cahnged the cache slider
to go all the way right to say cache everything, not just the last so many days, but this did not resolve the issue either.
Upon further testing I have the same issue when I use Search-Mailbox with Targetmailbox and TargetFolder to my "Discovery Search Mailbox". The folders is created and logs are made, but the folder does not show unless I am in exchange online
mode and not cached.
HELP PLEASE! This is very annoying and we need cached mode for the registry key to place sent mail in "SenderAndFrom" sent items. It doesn't work in online mode.

Hi CHase,
shared mailboxes shouldnt be cached,only user mailboxes should.Reason for this is because it will download all info from shared mailbox and it can take some time.All company info will also be stored locally,so its security concern.
You mention that you turn on cached mode,is this under user mailbox or additional mailbox as shown below?
The one to left should be fine to cache all,but the one to the right only first check mark should be on.We have this configuratuon and senderandfrom registry works well.
If you access OWA,then choose to open another mailbox,then choose the "support center" mailbox,do you see all folders?
By granting full access doesnt give you send as permission,for this you will need to run this command:
Get-Mailbox "[email protected]" | Add-ADPermission -User "[email protected]" -ExtendedRights "Send As"
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. That will encourage me - and others - to take time out to help you. Thank you! Off2work

Shared mailbox not working on 2007

Hello,
i'm having a problem generating a shared mailbox and making it work, here's the BG info:
Created a universal security group called "info access" with two users which need MB access
we have domain.local internal and domain.com external
i created the mailbox with the cmdlets:
New-Mailbox -Name:'Info customer' -OrganizationalUnit:'domain.local/main' -Database:'Mailbox Database' -UserPrincipalName:'[email protected]' -Shared
Add-MailboxPermission info -User:'info access' -AccessRights:FullAccess
Add-ADPermission info -User:'info access' -ExtendedRights:Send-As -AccessRights:ReadProperty, WriteProperty -Properties:'Personal Information'
Set-Mailbox -Identity info -GrantSendOnBehalfTo:'info access'
Everything completed ok, i see the hsared mailbox in the EMC, i see it can receive mails, but when i go to add the mailbox to one of those users outlook it gives error "outlook cannot open mailbox, the user cannot access the location", OWa also
fails but with a hard crash message with mapiexceptionlogonfailed
what is going on?, i double checked on the EMC and i see the permissions granted to the group, do i need to apply permissions to each user?

Hi Eliminateur,
Thank you for your question.
The name of shared mailbox is “info customer”, so we could run the following command to grant full access to “info customer” :
Add-MailboxPermission –Identity 'Info customer' -User:'info access' -AccessRights:FullAccess
Add-ADPermission –Identity 'Info customer' -User:'info access' -ExtendedRights:Send-As -AccessRights:ReadProperty, WriteProperty -Properties:'Personal Information'
Set-Mailbox –Identity 'Info customer' -GrantSendOnBehalfTo:'info access'
Then we could check if we could open shared mailbox which name is “Info customer”.
If there are any questions regarding this issue, please be free to let me know.
Best Regard,
Jim

Exchange 2013 mailboxes not accessible in outlook

Hi,
In the middle of migration from one exchange 2010 server to 2013 server and thought things were going well. However migrated mailboxes to exchange 2013 are not accessible through outlook although they are through OWA most of the time.
I ran test connectivity comandlet on 2013 server on mailboxes and they tested okay.
However when you connect to mailbox it says exchange unavailable.
I have a new ucc certificate on the exchange 2013 server that includes mail.contoso.com and autodiscover.contoso.com. These are both setup to point to 2013 server with split brain dns. The 2010 server has a certificate for mail.contoso.com.
The SC for autodiscovery right now for both the exchange 2010 and 2013 servers are https://mail.contoso.com/autodiscover/autodiscover.xml
When I run outlook connectivity test I get the following failure:
Test Steps
Attempting to ping the MAPI Address Book endpoint with identity: exg:6004.
The attempt to ping the endpoint failed

Shared Mailbox not archiving

We have in place archiving setup in Exchange 2013. Archiving is functioning perfectly for our standard mailboxes however for our shared mailboxes they are not archiving automatically, we have enabled the in-place archive, and it has been switched on for
over a month now and still the size of the archive mailbox is 3kb.

Hi,
Do you place this shared mailbox in the mailbox database DB01?
If you place the shared mailbox in it, please use the following command to check content index status.
Get-MailboxDatabaseCopyStatus -Identity "Mailbox Database" | fl *index*
If the index state of database is unhealthy, please bring to healthy state and then apply retention policy to move items to archive mailbox to check result.

Exchange 2013 (Office 365) shared mailbox not staying up to date.

We have created a new shared folder for multiple users to access in Office 365 and were having some issues. There are a few users where this mailbox works great, but others users aren't able to see any changes that are made in the shared mailbox.
Opening the mailbox in O365 shows all folders, emails, etc... but for some reason syncing stops working randomly after a bit of time. Removing and re-adding permissions to the mailbox does fix this issue, but that's not a feasable fix for us.
Users can add folders to the shared mailbox, and those added folders do show up in the mailbox when opened in O365, but the changes do not push down to multiple other clients.
Anyone else seen this or have any info? Thanks!

Hi,
Are the users using Cached Exchange Mode or Online Mode? When the issue comes next time, have the user switch to the other mode and test if this helps.
We can disable Cached Mode for Shared folders, check if this helps resolve the sync issue:
Go to FILE -> Account Settings -> Account Settings -> Double click on the Exchange account -> More Settings -> Advanced tab -> Uncheck "Use Cached Exchange Mode", and click Apply then OK.
In Cached Mode, it doesn't connect to Exchange Server all the time but keeps a cache of the mailbox locally to sync the local cache and mailbox according to a period, this may cause some items not sync immediately. By switching to Online Mode, it should
be immediate.

Do you have, on the BES, reconcile hard deletes? Does it reconcile if the user hits menu > reconcile now?
Reconcile Hard Deletes is under

Outlook 2010 Problem opening shared mailbox "the set of folders cannot be opened. Microsoft Exchange is not available"

Hi, I have a number of mailboxes configured for sharing.
For those users who have full access rights (given via EMC) the mailboxes automatically appear in Outlook 2010.
However for one of those mailboxes the users recieve the following error when they try to access it:
"The Set of Folders cannot be opened. Microsoft Exchange is not available. Either there are network problems or the Exchange server is down for maintenance."
Meanwhile the users' primary mailboxes continue to work as normal, as do the other mailboxes that have been shared with them.
The output of get-mailboxpermissions for the problematic mailbox is the same as the output for a full working one.
If I add the mailbox to my account (as though I was using Outlook 2003) it allows me access, however I then have the situation of having the mailbox listed twice, one working the other not.
How do I get this mailbox to behave as expected?
Many thanks
Nick

So the problem returns. I'm not sure what we did to work around it, the users who were having the problem have left and the new batch are now encountering it.
I have issued the following command on the Exchange Server (one site, one server, all roles, only a default throttling policy exists):
$a = Get-ThrottlingPolicy | where-object {$_.IsDefault -eq $true}
$a | Set-ThrottlingPolicy -RCAMaxConcurrency 40

But the problem remains. Do I need to adjust anything else for this value (40) to become active? The documentation implies that the above is required on a CAS, however there is mention of registry settings but no guidance on whether these are required if
the above is used.
When I create a second profile via Mail (in control panel) for the shared mailbox and then start outlook using this profile I am able to access the mailbox as expected. This is running in the context of the user who cannot access it from her
default Outlook profile.
Many thanks

Shared mailbox shows emails and subfolders of the users mailbox in Outlook

After We migrated the Exchange from 2010 to 2013 any shared mailbox has been migrated is showing the inbox and all the subfolders from the user's mailbox in Outlook, instead of the shared mailbox content.
note: if we create new shared mailbox it works fine without any issue.
We have tried to removed full access permissions and re-added full access permissions, disabling AutoMapping and then added the shared mailbox manually in Outlook and that works fine but it is not a solution for us as we have 400+ shared mailbox and
we cannot do it for every user have access on each shared mailbox.
any ideas.
Ayman Saleh

Hi,
Please check if this issue persists in Outlook online mode.
After you remove the full access permissions, the shared mailbox will disappear from Outlook automatically. When you add the full access permission then, the shared mailbox will appear again in Outlook. There is no need to add shared mailbox manually.
Please remove the full access permission and then re-add the full access permission. This time, you can make use of the AutoMapping feature to check if shared mailbox display properly.

Opening a shared mailbox in Outlook 2013 (office 365) returns "Cannot Expand Folder" error.

Hi!
We've just upgraded from our old Domino email server to Office 365 E1 and running an on-premise Exchange 2013 hybrid server.
In Outlook 2013, when trying to expand a shared mailbox, It asks me to enter my outlook credentials. Trying so doesn't work and it continues to ask repeatedly. If I click cancel, I get the following error:
"Cannot expand the folder. The set of folders cannot be opened. Microsoft Exchange is not available.
Either there are network problems or the Exchange server is down for maintenance."
The error only occurs in Outlook 2013 and it happens to all staff who are using Outlook 2013. Shared mailboxes are accessible in Outlook 2010 and OWA with no issues.
I have tried recreating profiles, removing and re-adding permissions, disabling auto-mapping. I've tested with creating shared mailbox in Exchange Online and on our hybrid server.

Hi,
Check if the kb below matches your scenario:
https://support.microsoft.com/kb/2992644
This problem occurs only when the following conditions are true:
You are using Microsoft Outlook 2013 client version 15.0.4641.1001.
The client is connected by using Outlook Anywhere (RPC over HTTP).
To resolve this issue, apply the update that is described in the following article in the Microsoft Knowledge Base:
2889859
If you are using the Click-to-Run version of Office 2013, the Outlook application is kept up to date automatically. For more information about Office 2013 Click-to-Run updates, see
Microsoft Office 2013 Click-to-Run virtualization
I hope the information is helpful.

Shared mailbox contacts to Address Book

Hi all
We have recently migrated to an Exchange 2010 environment, our clients using Outlook 2003 and Outlook 2010.
We have a large number of shared mailboxes within our organisation that contain their own contacts lists. The shared mailbox is added as as additional mailbox to the users' own profile as they have been delegated full access to manage
and maintain all items.
The issue we are having is trying to get the contacts list on the shared mailbox to show up in the users address book when sending an email.
I have had a search on the net for an answer to this and the only thing I can get to work to is creating a new profile for the shared mailbox and renaming the contacts as discussed in the following thread: http://social.technet.microsoft.com/Forums/en-US/exchangesvrclients/thread/62befbae-ceaa-482b-b450-e448f8d1a265
The issue with this however is that it only seems to temporarily work - after closing the profile for the shared mailbox and opening the user profile it will only appear in the address book for the first time; after closing and reopening Outlook
the contacts list for the shared mailbox disappears.
Even if we did get this method to work every time, it seems a little long winded. Some shared mailboxes are used by about 10 different users and having to get them to create a new profile for the shared mailbox seems a little full on just to get
the contacts list to show up in their address book.
Other threads on the net have suggested just going into the properties of the Contact item on the shared mailbox and ticking the "Show this folder as an e-mail Address Book". The issue I am having is that the there is no such tick box. In fact the
"Outlook Address Book" tab isn't even there. The users' have been given full control of the contacts as they are able to create/modify/delete contacts when they actually select the contact objects from the shared mailbox.
We have just moved from an Oracle mail environment where this was possible and so would like to know if sharing contacts is a supported feature of Exchange 2010/Outlook. If so, how?
Cheers
Brady

hi,
Outlook 2007, Exchange 2007, Win 7
i have followed all the solutions that given below but none seem to work. all i want is to show the shared mailbox contacts in my addressbook.
I do not want to login to windows using shared mailbox credentials to access contacts.
i dont no want to copy the or export contacts over.

Sharing a calendar of a shared mailbox

Hello
We have a group of people that need a common calendar so that sounds simple enough, right? I created a shared mailbox and set the permissions on the calendar for everyone that requires access to Owner. I thought that would be it but nobody can
add anything to it. They can see the calendar but if they try to do anything in it they get the error "Cannot open the free/busy information. You do not have sufficient permission to perform this operation."
You can't log into OWA with a shared mailbox account even after you enable it, so I can't share the calendar that way.
I know I can fix this by giving the users Full access to the mailbox in EAC but that would add the shared mailbox to everyone's Outlook which we don't want. I also know I could fix that problem by going into ADUC and removing the delegate attribute
in the mailbox account but do I really need to go through these hacks just to set up a shared calendar?
We are using Exchange 2013 with Outlook 2007

Hi Hutch,
You need to give Folder Visible permission on the Top-Level folder(including any parent folder if exists) of the mailbox and on the calendar too if not given.
Once done, it will allow user to see the calendar and only items below which they have permission to.
This will not show all the items inside the parent folder.
FolderVisible The user can view the specified folder, but can't read or edit items within the specified public folder.
Set-MailboxFolderPermission -Identity [email protected]:\Calendar -User [email protected] -AccessRights FolderVisible

OWA continuously prompts MailUser user when saving appointment for shared mailbox

We have a number of users of type 'mailuser' who are granted full permissions to shared mailboxes. If a user of mailuser usertype does the following, they are unable to save appointments to the shared mailbox's calendar. Outlook Web App will
continuously prompt the user to re-login. The functionality works in IE but *not* in FireFox (Update v28.0) and Chrome - I know probably beyond what can be fixed server-side but never hurts to ask.
Steps to reproduce:
1. Mailuser user is granted full access to a shared mailbox.
2. Mailuser accesses shared mailbox in OWA at https://mail.myorg.com/owa/[email protected]
3. User goes to the Calendar within OWA and double-clicks a timeslot to add an appointment. After appointment details have been entered, click "Save and Close"
4. Outlook Web App responds with a login prompt (same as initial prompt) and the user is unable to add the appointment - can't re-login via the prompt using the mailuser username and password.
Thanks.

Hi,
I have tested in my Exchange 2007 environment with IE. I can user mail user's credential to access shared mailbox can add appointments perfectly.
Please make sure the shared permission is set to Full Access instead of other mailbox permission. Also confirm the web browser for OWA access is a supported browser with OWA premium. If the issue persists, pleae remove the mailbox permission then re-add
it back to have a try.
