Ymail user deletes appointment sent by Outlook 2010 user

Hello,
An Outlook 2010 user sent an appointment to about 20 individuals, some gmail, some ymail, some exchange users.  The ymail user deleted the appointment from their calendar because
they could not attend, and the deletion removed the appointment from the originating user (Exchange/outlook 2010) calendar, and automatically sent cancellation notices to all of the other users.
What is going on here?  Thanks in advance,

Hello,
Normally, the recipient will not delete appointment from the organizer's calendar.
Please make sure you use exchange version. If you use exchange 2010/2013, I recommend you use Get-MailboxFolderPermission -Identity the organizer's SMTP Address:\calendar | fl cmdlet to level permissions for a folder.
Besides, please check if the issue occurs when other users( such as gmail users or exchange users) delete appointment.

  • Outlook 2010 users getting Password Prompt until shared mailboxes are removed

    Hi,
    some (around 20) of my 3000 outlook 2010 users are getting Password Promts while using outlook.
    This started end of last week without any change to the environment.
    The prompt goes away if we unmount and remount additional mailboxes they have mounted.
    Any idea what could be causing this or where to start debugging?
    Backend is Exchange 2013 and 2007 in migration. 
    Thanks for every idea

    Hi,
    How did you mount additional mailboxes? Via File > Account Settings > Account Settings > Double-click the Exchange account > More Settings > Advanced tab > Add?
    Are the additional mailboxes hosted on the same version of Exchange server with thoese mailboxes with the password prompting issue? If this is the case, this issue often happens if you have a hybrid deployment of Exchange Server. To resolve the issue,
    please have a look at the following KB article and follow the instructions to fix it:
    https://support.microsoft.com/kb/2834139?wa=wsignin1.0
    Please let me know the result.

  • Delete Button Disabled in Outlook 2010 with Exchange 2013

    I recently switched from a 3rd party mail software to Microsoft Exchange.  I have had some users ask me why the Delete button is disabled.  I didn't enable any special policy to cause this, and the Delete key on the keyboard will delete messages. 
    The disabled Delete button I am referring to is in the Home ribbon and the right-click menu for selected e-mail(s).  Is this standard behavior for Exchange, and can it be changed?

    It so happens that I have an XP VM with Outlook 2007.  That having been said, as previously mentioned, before testing, I (thought I) could confirm the same consistent behavior in the following configurations:
    WinXP + Outlook 2003
    Win7 + Outlook 2010
    Each of these systems was using a different user account, and I have tried folderview repairs in EMC to no avail.
    Strangely, WinXP + Outlook 2007 does not appear to exhibit the behavior.  In this test case, the profile and OST were just created, but switching to folderview or moving the reading pane to the bottom did not affect the behavior.
    Given that information, I proceeded to re-verify, and I hadn't checked winXP + Outlook 2003 because the computer in question had been upgraded to Outlook 2010.  However, I verified the issue does still exist there.  Next, I proceeded to check another
    computer that I thought would be WinXP + Outlook 2003, but it had also been upgraded to Outlook 2010.  This computer did not have the issue, and this leads me to a new theory about the cause (but no closer to resolution).  For the record, of the
    three computers (two exhibiting the issue, one not), only one has the Adobe plugin mentioned in my last post in response to Diane Poremsky, so the issue doesn't appear to be related to that.
    That said, my theory follows:  This is somehow related to IMAP in Outlook 2010.  The computers that exhibit the issue were all previously running IMAP in Outlook 2010, and the IMAP PST filse were imported using the MailboxImportRequest feature. 
    I suspect this is related because of other issues that happen for these accounts.  For instance, all new e-mail was only visible in OWA and not Outlook on all folders on these accounts, and I have had to have the users reset filters in the view settings
    for each folder individually.  I don't remember exactly which filter was somehow imported, but it definitely had to do with IMAP.  This may be another red herring, but the behavior is consistent with it.  I should also note that this behavior
    did NOT exist when they were connected via IMAP to the old (non MS) server.  I should also note that the filter behavior is somehow stored on the server (and therefore I imagine the delete button behavior could be as well), because creating a new Windows
    Profile  (and as such, a new Outlook profile and OST file) on a new computer did not make the IMAP filters go away.

  • Very slow calendar sync with Outlook 2010 users.

    Hi guys.
    My company is running Office 365 with hosted Exchange. Most clients are using Outlook 2010 and are reporting that when trying to access shared calendars, all operations are incredibly slow and can take up to a few minutes to show any calendar items. I'm one
    of the only users on Outlook 2013 and the Outlook 2013 users don't seem to experience as much of an issue, but it is still there. Is there a way I can look into this to fix it?
    Having the calendar shared all over again doesn't seem to fix. It's been suggested that I should run the O365 setup from OWA again - is there any ground to this?
    Thanks for your help.

    Hi,
    Please follow the troubleshooting steps below on this issue:
    1. Disable the firewall and anti-virus program to test again.
    2. We may suspect there’s a 3rd-party add-ins that may be the possible reason, let's run Outlook in Safe Mode, to determine if it is 3rd-party add-ins related.
    Press Win + R and type “outlook.exe /safe” in the blank box, then press Enter.
    If there’s no problem in Safe Mode, disable the suspicious add-ins to verify which add-ins caused this issue.
    3. Go to File tab -> Account Settings ->
    Account Settings -> Double clicking on the account name ->
    More Settings -> Advanced tab ->
    Download shared folders, tick or untick the checkbox to check the result.
    4. If the steps above don't help, simply create a new profile to setup the account:

  • "changes to the public group membership cannot be saved" error from Outlook 2010 users, but no problem with Outlook 2003.

    We have the exact same issue as this but our groups are already universal security group and we still have problem:

    The distribution-groups were upgraded to Exchange 2010.  User A can update the group from Outlook 2003 or OWA 2010 but not from Outlook 2010.  Anyone know the solution?
    thanks

    Hi lilyl,
    For this issue, please refer to this document:
    How to Manage Groups that I already own in Exchange 2010?
    http://blogs.technet.com/b/exchange/archive/2009/11/18/3408844.aspx
    So what does the "Changes to the distribution list membership cannot be saved. You do not have sufficient permission to perform
    this operation on this object." error mean, when you are connecting to an Exchange 2010 server?
    It means Exchange 2010 is doing its job - as designed...

  • Cant delete task notification in Outlook 2010

    In my Office we use Outlook 2010 and I assign tasks to various people.  When they accept the task I receive a notification however in the last few days I have received a few notifications that I can't delete.  When I select the notification in
    my Inbox it says "This item cannot be displayed in the Reading Pane.  Open the item to read its contents" however if I try to open it I get "Cannot open this item.  The attempted operation failed.  An object could not be found."
    If I try to delete the task notification I get "The attempted operation failed. An object could not be found.".
    I've tried running the repair function but it didn't help.  How can I fix this so it doesn't happen going forward and delete these email?
    Thank you for the help!

    Hi,
    The first thing you need to do is to make sure Outlook is fully patched.
    Some anti-virus program may cause this issue, to verify that, please disable the firewall and anti-virus program, then start Outlook, check if the issue persists.
    You can also run 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 there’s no problem in Safe Mode, disable the suspicious add-ins to verify which add-ins caused this issue.
    Note For the steps above, I suggest you test with the new notifications.
    You can also try the following and check if it helps:
    Click on the File menu –> Options, navigate to Advanced tab and scrolled down to Send and receive section, then click on the Send/Receive button. In the ‘Send/Receive Groups’ window, click on Edit tab. In the 
    ‘Send/Receive Settings’ window, click to select the email account under ‘Accounts’ and then click to select the ‘Download Complete Items’ option. Make sure the option “Download only headers for items larger then” is unchecked/not selected and click on Ok.

  • Outlook 2010 User can't access free/busy info for one resource mailbox calendar

    There are a couple posts that are similar, but I haven't been able to solve this one yet.
    We just recently moved our conference room calendars from public folders to proper resource mailboxes. Aside from users not RTFM on how to use them the move has been fairly painless. Until now. I have one user that can't see the free/busy info on one of
    the room calendars. Just one. We are using Exchange 2010 and he is on Outlook 2010. When he tries to view a meeting in the calendar he gets an error, "Cannot open this Item. Cannot open the free/busy information."
    He has no problem opening meetings for that room on OWA, so it leads me to believe it involves some temp files or cached info on his machine. 
    I tried using /CleanFreeBusy on his computer and it did not remedy the situation. I removed his profile and added it again which appeared to work, but five minutes later when I got back to my desk he could no longer open the meetings. 
    Any insight would be much appreciated. I admit I am an amateur when it comes to Exchange admin.

    Remove and recreate the Outlook profile from their machine? I did this and it worked for a few minutes.
    By resetting his profile do you mean removing his profile from the machine and recreating it after backing up all his user data?

  • Issue with Exchange 2007 SP3/Outlook 2010 User account Auto accepting Appointments

                                
    0
    Hi
    I have an issue with 2 users who's appointments are being Auto-accepted or Auto Declined. As these are User Mailboxes there is no resource scheduling set on these. I've also checked for delegates (none), Rules (including running outlook.exe /cleanrules).
    If I send the user some test appointments when they are not logged into Outlook, the appointments are not processed. If the user logs in through OWA then the appointments are not processed. When the user logs into Outlook 2010 (using Mapi) the appointments
    are processed within 5-10 minutes. I started to think it may be a PC issue, something buried in the registry. But I give myself full access to the account and logged in from my machine using Outlook 2010, the appointments are auto processed, again, within
    5- 10 minutes .
    Lots of stuff on the internet all pointing to Resource scheduling, delegates or Rules but I have now discounted all of these.
    If I check the users MailboxCalendarSettings, AutomateProcessing is set to AutoUpdate and not AutoAccept. The Outlook Client has all settings in Resource Scheduling unticked.
    Thanks
    Darran

    Hi Darran,
    If there is no delegate configured, no rules and calendar processing is also set properly, please switch Outlook to Online mode to check whether the issue persists. Also close Outlook and receive test meeting request directly in OWA to double check the mailbox
    would not automatically process the meeting in OWA.
    If the issue happens in Outlook Online mode but not continues in OWA, please restart Outlook in safe mode or change a new computer with fresh Outlook 2010 to have a try.
    Thanks,

  • IPAD3 does not automatically update after deleting a contact from Outlook 2010 over ICloud

    I've noticed that when deleting a contact on my IPAD 3, it automatically deletes the contact on my PC (Outlook 2010 set up for ICloud).  However it doesn't work or update the other way around.
    I can edit an existing contact on Outlook, or add a new contact on Outlook, and that always updates on the IPAD3.. But it doesn't update on the IPAD when deleting from Outlook which is strange.
    If I delete all the contacts on the IPAD and then re-sync once again to ICloud, then it is as it should be and any previously deleted PC contacts, do not show on the IPAD. 
    Any thoughts as to what might be happening?

    Hi Kumar,
    Please remove the codeline $List.Update();, then run your code again, it works for me.
    You may need to firstly delete the synced contacts list within Outlook to remove those undeleted accounts, then re-connect the SharePoint contacts list to outlook, then run your modified Powershell code.

  • After Migrating To Exchange 2013 All Outlook 2010 Users Constantly Prompted For Password (BUT OUTLOOK WORKS).

    I have two servers.  One is Exchange 2010 and the other is Exchange 2013.
    Three of our users had mailboxes on Exchange 2013 for the last few weeks with no problems.  They used Outlook 2013 and Outlook 2010.  After moving the rest of our ~25 users to Exchange 2013 the users with Outlook 2010 began to be prompted for their
    password constantly.
    They try entering it and it immediately reappears.  
    The odd thing is it shows connected and they are able to send and receive emails correctly.  
    I've tested our exchange connectivity using www.testexchangeconnectivity.com and all is well there.
    I'm not really sure what's going on.
    Any help is appreciated.  
    Luke
    Thanks, Luke Pickard

    This can appear if Outlook clients are trying to connect to OAB virtual directory, and don't succeed for some reason. Mailbox and mailflow will work, but password prompt will appear when Outlook tries to contact OAB. Try to investigate in that direction.
    Also, perform Outlook Configuration test (right click Outlook icon in task bar while holding CTRL and select Test email autoconfiguration.

    My outlook is asking for username and password in outlook 2010 after installing the icloud for pc.   it says to use my apple id,  but that does not work.  Any suggestons?

  • Outlook 2010 - User tends to open many emails at a go but this may slow down the machine.

    Hi,
    My user tends to have this work habit of opening 8-10 emails at one go. She view this way of working as more efficient and faster. But this means that if outlook crashed, all the emails will be close as well, and this way of working tends to slow down the
    machine.
    Is there any way Outlook can users to open multiple emails without hording CPU page milage?
    Thank you.

    Hi Josh,
    Slow Outlook can be also harmful for your database and there are numbers of factor which slow down the MS-Outlook like:
    * Third Party Plug-ins
    * Slow internet connection
    * Antivirus/ Firewall Programs
    * Corruption or Error within Outlook
    So always try to open Microsoft Outlook in safe mode whenever you stuck in such problems. 
    How to optimize Outlook performance:
    * By Disabling add-ins
    * Check default account settings
    * Disabling Scanning programs
    * Scanpst.exe (Inbox Repair Tool)

  • Exchange 2003, SBS Server, Outlook 2010, User Over Limit, 2 GIgs

    I have a user's who's account is over limit. I have recently done a clean install of Windows 7 Professional and Office 2010. I keep trying to have his computer archive old emails but in the process the machine keeps hanging. I try to crash out Outlook
    but the outlook.exe process will not let me shut it down telling me access denied. The only way to recover is to completely shut down the computer (which I cannot do VIA the regular shutdown option because of outlook hanging). What do I have to do to resolve
    this problem? Kind of urgent as it's affecting his receiving emails.
    Vern

    Hello,
    According to your description, the issue seems to be related to outlook profile or your PC. I recommend you check if the issue occurs when other users use the PC. If the issue doesn't occurs, it means your outlook profile should be problem.
    If the issue persists, please check if there is related error in application log.
    If there is any update, please free let me know.
