Shared Calendar Send As Behavior & Legacy Shared Mailboxes

Ok Exchange Gurus, here's the scenario:
Shared Mailbox 1 - Legacy Exchange 2007 shared mailbox with the SendAsItemsCopiedTo attribute set to SenderAndFrom, then migrated to full Exchange 2013 environment, with no Exchange 2007 servers left.
Shared Mailbox 2 - Exchange 2013 created shared mailbox.
Shared mailbox 1 still exhibits the same behavior when a user sends as that mailbox, the sent item is put in both the Shared Mailbox 1 sent items folder, as well as the user's sent items folder.
Shared Mailbox 2, the sent item is only placed in the user's sent items folder, and not the Shared Mailbox 2 sent items folder.
I know the Set-MailboxSentItemsConfiguration command has been removed from Exchange 2013, so obviously, Powershell isn't the answer to modify shared mailbox 2 to act the same as mailbox 1.
My question then is, if Shared Mailbox 1 was migrated to Exchange 2013, that attribute still HAS to be somewhere for Exchange 2013 to still deliver the sent item to both the user's mailbox and the shared mailbox. I've checked every attribute on Shared
Mailbox 1 in Powershell, AD, ADSIEdit...and cannot find anything. Again, Exchange 2013 still has to read this attribute SOMEWHERE to know that it has to deliver the message to both sent items folders.
A big virutal beer will be sent to whomever figures this one out!!!
Thanks!

Hi Statik,
I find the solution from a similar thread. Information as below:
I found out that i have to use the registry for this:
DelegateSentItemsStyle, type REG_DWORD and set it to 1 (default is 0 or not present). HKCU\Software\Microsoft\Office\<version>\Outlook\Preferences
More details to see:
Where is Set-MailboxSentItemsConfiguration / Get-MailboxSentItemsConfiguration?

Hope it is helpful.

Outlook send as from shared mailbox

HI all,
I have a problem with sending email from a shared mailbox on user accounts. The sent items go to the sent items folder on of the sender, but I want them to go the Shared mailbox sent items (so that other user can see a reply has been sent).
Now I have been searching on Google and found these steps:
To do this, follow these steps:
Click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Preferences
On the Edit menu, point to New, and then click DWORD Value.
Type DelegateSentItemsStyle, and then press ENTER.
Right-click
DelegateSentItemsStyle, and then click Modify.
In the Value data box, type 1, and then click OK.

Full Access and Send As are two different things. Granting Full Access does not confer Send As. In fact, Full Access is granted on the mailbox in the mailbox store, while Send As is granted on the mailbox's user object.

Okay, that is what I thought. (The internet lied to me) I added myself to the Syssupport mailbox with full access AND send as permissions and I received the test email so now that is working. Thank you for clearing that up.

Notifications from a shared mailbox calendar to a group of people

HI
When a member of staff books a meeting . They add meeting room support as an attendee of the meeting if they need IT assistance .
I would like the meeting room support to be a shared mailbox or calendar that sends notifications to a group of people when a meeting is going to start as if it was in my calendar .
The problem is at the moment we have to accept all meetings to get that notification , so my presence and other members of the groups is always set to busy
We are using Outlook 2010 . I read somewhere that was a new feature of 2010 and wasn't a feature of 2007 . Can somebody just clarify that this is possible and how best to do it
Thanks
MM

Hi,
There is no such build-in feature in Outlook. As you mentioned, you can accept a meeting and then you will get the notification, this is how it works.

Outlook 2010 Shared Mailbox Outbox Send Immediately Issue

Hello,
So we have a weird problem tat we have being trying to diagnose for a while and I think that I have finally got to the bottom of the problem, just now need to find a solution.
We have a shared email email account. This is set up as shared mailbox in exchange (2010) with Full Control and Send On behalf of privileges given to three users. Each of these users has added this shared mailbox
as a second account to their outlook (2010) profile.
The Problem we have appears to be two fold. For some reason emails are not sent immediately for this account even though this is value of the setting in outlook. This puts an email in the shared mailbox outbox. We then have a race condition where by the
first user of the shared mailbox whose outlook client does a send an receive first becomes the user who sent the email on behalf of the shared inbox rather than the user that hit sent. This has caused mild confusion for the recipients as signatures of the
email does not match what outlook is displaying.
So, firstly is this expected behaviour for shared accounts, that the outbox is shared so this race condition will always exists?Secondly, any idea why on this second mailbox attached to outlook emails are not always sent immediately? In fact this appears
to be a bigger problem, email not getting sent until people hit send and receive has just happened to someone else. What can I do to diagnose this issue?
Cheers
Rich

Hi,
Based on the description above, the issue is that when you send an email message from a shared mailbox, the sent email message remains in your Outbox until you manually perform a Send/Receive operation.
As far as I know, this problem occurs when both the following conditions are true:
Your Outlook profile is configured in online mode (not cached Exchange mode).
You have the DelegateSentItemsStyle registry value set to
1.
If you are using Online Mode, please switch to Cached Exchange Mode to check the result, if the issue doesn't occur then, please note there is no resolution to this problem other than to either switch your profile to cached Exchange mode or set the DelegateSentItemsStyle
registry value to zero (0). Additionally, if your mailbox is located on Microsoft Exchange Server 2010 (or later), the Exchange administrator can configure similar behavior on the server.
Important
Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it,
back up the registry for restoration in
case problems occur.
To change the value of DelegateSentItemsStyle to 0 in the registry, follow these steps:
Exit Outlook.
Start Registry Editor.
In Windows 8 and Windows 8.1
Swipe in from the right to open the charms, tap or click Search, and then type
regedit.exe in the search box. Or, type regedit.exe at the Start screen, and then tap or click
regedit in the search results.
In Windows Vista and Windows 7
Click Start, type regedit in the Start Search box, and then press Enter. If you are prompted for an administrator password or for confirmation, type the password, or click
Allow.
In Windows XP
Click Start, click Run, type regedit, and then click
OK.
Locate and then select the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Office\<var>x</var>.0\Outlook\Preferences
Note In this key path, the placeholder <var>x</var>.0represents
15.0 for Outlook 2013, 14.0 for Outlook 2010,
12.0 for Outlook 2007, and 11.0 for Outlook 2003.
Select the DelegateSentItemsStyle value.
On the Edit menu, click Modify.
Type 0, and then click OK.
Exit Registry Editor.
Start Outlook.
More details about the issue can be found in this kb below:
Email remains in the Outbox when you use the DelegateSentItemsStyle registry value

Is there a way to create a rule that sends and Auto Response for a shared mailbox?

I have a shared mailbox set up that receives emails that are sent to 3 different addresses:
[email protected]
[email protected]
[email protected]
I would like to create a rule that would send an auto response when someone emails one of these addresses. However, I don't want an auto response sent to [email protected] so I can't just set up an "out of office" reply for the mailbox.
Is there a way that I can create a rule to send an automated response to 2 of the 3 addresses?
Nate

Hi
we can enable the shared mailbox in ADUC and create Outlook rules for it in Outlook to achieve it. please follow these steps:
1. In Active Directory Users and Computers, right-click the shared mailbox and click Enable Account.
2. Configure the Outlook account for the shared mailbox in Outlook.
3. Click Rules > Manage Rules & Alerts.
4. Create a rule like the following format:
Apply this rule after the message arrives
Have server reply using a specific message
Except if the subject contains specific words
Select exception(s) (if necessary) of the Outlook Rule - (“except if from people or public group“)
5. Apply the auto reply rules for this shared mailbox.
Then users can receive auto reply of the shared mailbox except the exceptions we have set when they send messages to this shared mailbox.

Shared mailbox - send as and auditing Exchange 2007

Got 3 users A,B,C who all access a shared mailbox X.
They have a requirement to be able to answer emails sent to mailbox X BUT the return address to be X (i.e. not their own or send on behalf etc) so any subsequent relies still go to X and not the individual email addresses.
However, enother requirment is that there needs to be a way to determine which user (A, B, or C) actually sent the email from shared mailbox X.
Any way at all to do this?

Hi,
Since the full access permission has been assigned to users, please give Send As permission to these 3 users (A,B,C) for this shared mailbox X. Then user A,B,C
can send as the mailbox X with the From field shown as Mailbox X. Please follow these steps to set it:
1. Make sure the Full Access permission have been configured correctly.
2. Give send as permission to UserA, UserB and UserC for shared mailbox X.
Add-ADPermission -Identity “Mailbox X” -User UserA -Extendedrights "Send As"
Add-ADPermission -Identity “Mailbox X” -User UserB -Extendedrights "Send As"
Add-ADPermission -Identity “Mailbox X” -User UserC -Extendedrights "Send As"
3. Then UserA, UserB and User C can send messages by the following steps in Outlook:
a. Click New Email > OPTIONS > From, then the From field is shown in the message.
b. Click From > Other E-mail Address, and select the Mailbox X.
Then the recipients would receive the messages which the From field is shown the Mailbox X name instead of UserA, UserB or UserC.
To track which user has send as Mailbox X to the recipients, we can enable message tracking log or
Mailbox audit logging to track it.

Users cannot edit a shared calendar of a shared mailbox that was deleted from the cloud and recreated on premise

Description:
The following example account [email protected] is an on premise AD account being used as a shared mailbox in the cloud. We have discovered that regardless of what we do, not a single user can edit the calendar entries.
The following message is shown in Outlook Click to Run 2013 when an entry. "New appointment" button is also greyed out, including "Calendar Permissions" and some others.
This problem started when the shared mailbox was created wrongly by creating it in the cloud first and we had to delete it and start over. The "in the cloud" user was deleted and the same user was created in AD on-premise with the same account name
and then Dir Synced with the cloud. A license was assigned, a user mailbox on exchange online created and the type was converted to a shared mailbox and Editor rights were defined on the calendar folder for specific users.
Actions performed:
Action01: gave users Editor rights on calendar folder through powershell
Result01: Rights correctly added and can be seen when get-mailboxfolderpermission is ran
Action02: Opened calendar with Outlook and tried to edit entries
Result02: Error message pops up saying "You don't have permission to create an entry in this folder. Right click the folder and check..."
Action03: Opened calendar with OWA of users
Result03: Users can edit the shared calendar on OWA
Action04: Gave users Full Access permission on mailbox with automapping on
Result04: Users can edit calendar in Outlook
Action05: Gave users Full Access permission on mailbox with automapping off (mailbox no longer visible in outlook)
Result05: Users cannot edit calendar in Outlook
Action06: Removed Full Access permission on mailbox for users
Result06: User cannot edit calendar in Outlook
Action07: Removed [email protected] from on-premise AD, performed dirsync, removed account from ms online using remove-msoluser -removefromrecyclebin
Result07: No trace of the account was anywhere to be found.
Action08: Created new [email protected] account on on-premise AD, assigned o365 license to user including exchange online license
Result08: New empty Exchange online mailbox was created
Action09: gave users Editor rights on calendar folder through powershell
Result09: Rights correctly added and can be seen when get-mailboxfolderpermission is ran
(Note: whenever mailboxfolder permissions are modified for this mailbox it's as if they are ran THREE times in a row, the first time they are applied and the powershell gives immediately 3 exceptions behind this:
An existing permission entry was found for user: [email protected]
    + CategoryInfo          : NotSpecified: (:) [Add-MailboxFolderPermission], UserAlreadyExis...nEntryException

nt.StoreTasks.AddMailboxFolderPermission
    + PSComputerName        : outlook.office365.com
Any other mailbox does not do this when setting mailboxfolder permissions)
Action10: Opened calendar with Outlook and tried to edit entries
Result10: Error message pops up saying "You don't have permission to create an entry in this folder. Right click the folder and check..."
Action11: Tried on a fresh new pc with first time logon
Result11: did not help
Additional information:
We have seen this problem with another user which was recreated, when he shares his calendar with others and people get the calendar invite email and click "Open Calendar" they receive a popup "The folder cannot be found".
My first impression points to a corruption/bug in the GAL on exchange online, since we're using o365 for midsize bussinesses we cannot use the AdressList role to expose the adresslist cmdlts for deeper troubleshooting.
PS:
Issue tested on different computers and with different user accounts, not a single user can edit the calendar of [email protected] when editor rights are given.
Noticed when editing rights for the shared mailbox in powershell after the first confirmation line
Office 2013 is click to run was updated to latest version, version number: 15.0.4659.1001

Greetings Gil,
I haven't heard of that one.
Questions:
Does the calendar in question show up in the "Subscriptions" category of iCal?
If you remove all accounts from iCal > Preferences > Accounts and quit and re-open iCal, does the calendar in question vanish? If so, does the calendar come back when you re-input the servers you need into iCal > Preferences > Accounts?
Can you provide a screen shot of your calendar sidebar.
While you answer those questions, some troubleshooting to try:
Try dragging one of your other calendars above this calendar that won't delete and then quit / re-open iCal and attempt to delete the calendar in question.
Failing that:
1. First make an iCal backup: Click on each calendar on the left hand side of iCal one at a time highlighting it's name and then going to File Export > Export and saving the resulting calendar file to a logical location for safekeeping.
2. Go to iCal > Quit iCal
3. Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
4. Launch iCal and test.
If the issue persists at this point:
Remove the following to the trash and restart your computer:
Home > Library > Caches > com.apple.ical
Home > Library > Calendars > Calendar Cache, Cache, Cache 1, 2, 3, etc. (Do not remove Sync Cache or Theme Cache if present)
Home > Library > Preferences > com.apple.ical (There may be more than one of these. Remove them all.)
---NOTE: Removing these files may remove any shared (CalDAV) calendars you may have access to. You will have to re-add those calendars to iCal > Preferences > Accounts.
Hope that helps!

Email stuck in outbox if sending mail from a shared mailbox

Hi,
Some user mailboxes have recently been migrated from Exchange 2003 to Exchange 2010. Shared mailboxes are located on Exchange 2003 still for the time being.
Some users have send as permissions to a shared mailbox. In Outlook the users are logged in as themselves and using the from field send an email from the shared mailbox.
The email is sent and delivered to its recipient.
The email is however stuck in the outbox of the users mailbox.
I have tried recreating the Outlook profile, windows profile and using a different PC, but the mails still get stuck in the outbox.
If outlook is changed to use cached mode then the emails are delivered. We don't want customers using cached mode though.
If I migrate the shared mailbox to Exchange 2003 I still have the problem.
If I migrate the users mailbox to Exchange 2003 then the problem goes away.
On the Laptop I am testing this on it is Windows 7, Office 2003. I have also tested on another computer with Windows 7 and Outlook 2007. Outlook safe mode doesn;t help or turning off windows firewall.
Has anyone experienced a similar issue?

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
Hutch

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

Send As from a shared mailbox stopped working

I have created a Shared Mailbox a few months ago and gave one use full access rights and send as permissions. This worked perfectly since it was created. On Friday, the user started getting:
Delivery has failed to these recipients or groups:
You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission.
If the problem continues, please contact your helpdesk.
There have been no changes made to any of the rights or permissions anywhere. The shared mailbox properties still show this user in the full access and send as list. The shared accounts address is available in the GAL so that is not an issue.
Any ideas would be appreciated. I could probably recreate this mailbox, but would rather fix the issue or at least know what happened in case it does it again.
Nick Laurino

Hi,
Have you tried removing and then re-adding the permission for the user? Worth a try when such issue occurs.
As the administrator, you may want to verify that the user actually does have "Send-As" permission on the shared mailbox. To do that,
Open the Exchange Management Console on the Server
Navigate to Recipient Configuration > Mailbox and right click the Shared Malibox
Select "Manage Send As Permission"
Check that the user is listed in the permissions
To solve the issue on the client side, delete the offline address book and allow Outlook to recreate it.
Close Outlook
Delete the Offline Address Book folder
It can be found under "C:\users\{username}\AppData\Local\Microsoft\Outlook\Offline Address Books"
Open Outlook and it will download a fresh copy of the Offline Address Book
I hope this can be helpful.

Shared Mailbox with Multiple Shared Calendars

We have a shared mailbox (Exchange 2010) for a department and they have created 30+ calendars that they would like other users to have access to. I've tried giving access to the calendars folder with powershell giving the users reviewer access which
is what was requested.
I started with this
Add-MailboxPermission -Identity "Dept42" -User "user" -AccessRights ReadPermission -InheritanceType all
then
Add-MailboxFolderPermission -identity "Dept42:\Calendar" -user "nrogers" -AccessRights Reviewer
I'm assuming this command gives access to all calendars folder since i've tried to specify the calendar and get errors that the specific calendar could not be found. Am I missing something as they still cannot see the shared calendar even though I can add
the mailbox to their outlook profile.
Thanks
Jay

Hi,
To share the sub calendar to other users, we need to give them the desired permission (at least Reviewer) to the folder and at least Folder visible permission to every Root folder above the shared subfolder.
Besides, we also need to give them Folder visible permission to the shared mailbox.
1. Right click on the mailbox root.
2. The Default account typically has no permission to the entire mailbox. You can either give the Default account Folder visible permission or click Add and select the users who you want to grant the permissions.
3. Check the Folder visible box only and the permission level remains set to None.
Once the Calendar folder permission are set, who the folders are shared with needs to add this shared mailbox to their profile.
Could you please check the result from Outlook side?
If there is any update, please feel free to let me know.

Outlook 2013 / Exchange 2013 : Shared mailboxes - Mail stuck in outbox (non-cached), Mail sends but doesn't get received (cached).

Hello,
We are currently experiencing some weird behaviour in Outlook 2013 since we added Shared Mailboxes.
When we run Outlook 2013 with cached mode
enabled:
- I create a new e-mail and send it.
- The e-mail goes to the outbox, and get's 'send'.
- None of the recipients receives the e-mail.
When we run Outlook 2013 with cached mode
disabled:
- I create a new e-mail and send it.
- The e-mail goes to the outbox, but remains there.
Now to make things even more bizarre:
When I switch from 'cached'-mode to 'non cached'-mode, I see all the e-mail that were 'send' in cached-mode stuck in the outbox.
Note: The DNS server configuration in Exchange is correct.

Hi,
How about sending on OWA? Does the issue exist?
To troubleshoot the issue, let's run Outlook in Safe Mode to determine if 3rd-party add-ins are related:
Press Win + R and type “outlook.exe /safe” in the blank box, then press Enter.
If there’s no problem sending emails in Safe Mode, disable the suspicious add-ins to verify which add-ins caused this issue.
Please also disable the firewall and anti-virus program to send the emails again, in many scenarios the protection may cause the issue.
Please also keep Exchange and Outlook patched to the latest.

Shared Mailboxes Send on Behalf

I have created shared mailbox and Grant Send On Behalf permission for John.
John sends email on behalf to shared mailbox but messages look like John send message himself (Send AS). But John have only Grant Send on Behalf permission not SendAS.
Exchange 2013 CU2.
Truly, Valery Tyurin

Hello,
I have similar issue but in reversal, I have a shared mailbox. I want to send an email on behalf of shared mailbox but I do not want the recipients to see the email has been sent by "User on behalf of shared mailbox". I have been added as a delegate
with editor permissions in shared mailbox. If I send an email (From option: shared mailbox) from my outlook, receiver can see that the email has been sent on behalf. I do not want this. It should be visible as if the mail is sent from shared mailbox.
I saw some suggestions that adding permissions on exchange server will help but I dont know where to check in the system (perhaps I dont have admin rights). I have a colleague, they are just new, they dont know about email box too. My old friend who left
has configured the outlook for these new ladies. For them it is absolutely working fine. I dont know what he did but would not have used exchange server (as we dont have admin rights).
Please help!

Random Ad Hoc meetings appearing in a shared mailbox calendar

Every now and then we keep getting some random ad hoc meetings appearing in a shared mailbox that we use for our team. There doesn't seem to be any correlating factors between the users that send these in and the users themselves are not aware that
they are sending them. What could be causing these?

Hi,
Ask these users who have this issue to change their password then login again, see if the same issue will occur in future.
We may also ask the users to always start Outlook in Safe Mode, to determine if it's 3rd-party add-ins related:
Press Win + R and type “outlook.exe /safe” in the blank box, then press Enter.
If this issue doesn't happen for a period, we may assume it's caused by add-ins, disable the suspicious add-ins to verify that.
If we still can't figure out the reason, we may use Mailbox Audit Logging to monitor these users' mailboxes to find out the reason:
