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:

  • 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.

  • When I open Mail the screen flickers random blue and gray appeared on the screen. I took a video too. Will that happen again? Is it hardware problem? This ipad2 32GB was replaced yesterday and I think it is refurbished. Are replace product refurbished?

    I got my ipad2 replaced yesterday. And this new ipad started giving me problem by crashing aps. Then I restored the ipad twice but the problem was still there. I called apple and they fixed it by doing Reset All Settings. But now I have this weird problem. When I open Mail the screen flickers random blue and gray appeared on the screen. I took a video too. Will that happen again? Is it hardware problem? This ipad2 32GB was replaced yesterday and I think it is refurbished. Are replace product refurbished?

    There is no way for anyone here to know if your replacement iPad is a refurbished unit.  Per Apple's replacement policy, replacements can be refurbished units.  If you feel the unit is not working correctly, take it back, let them check it out and if found defective, they will replace that unit.

  • How to make a Shared mailbox folder appear on everyones mailbox automatically

    Hello, I need to find a way for a Shared mailbox
    folder to appear in everyone’s mailbox automatically – preferably in their favorites. We currently have a Public Folder where everyone in the company can drag or email any suspicious, fishing, etc.
    emails. Unfortunately that is not good enough for our company's upper management. They
    wants me to find a way to add a folder on everyone’s mailbox so they can easily find it under their favorites and drag any questionable messages to it.
    I created a Shared mailbox for this purpose and a folder and I gave everyone access to it. Now
    I’m not sure how to make this folder appear automatically in everyone’s mailbox favorites. If there is a way to accomplish this I would appreciate any suggestions.  I wonder if there is a
    powershellcmdlet that can help me do this. Any assistance will be greatly appreciated. For now we are running on a mix environment Exchange 2010/2013, but pretty soon it will be 2013 only. Thanks in advance for your assistance.
     

    I wouldn't recommend this method, trust me this might become mess if doesn't go to right direction. People might use this shared mailbox for their
    own use. Best practice is to create a shared mailbox with some sensible name like [email protected] or
    something like that and then share it on the announcement board or send an announcement mail to all users and ask them to forward their spam, suspicious, fishing mails to this address.

  • Shared 2010 Calendar Color Categories not appearing in Outlook 2007

    I have a SBS 2003 (exchange 2007) environment wih a mixed Outlook use between 2007 and 2010. One 2010 Outlook client has shared a calendar to several 2007 users and they swear that when they received the email invite to view this shared 2010 calendar, the
    color categories list in their Outlook changed to match the shared calendar without any interaction from the users. A new hire was given the same invite to view this shared calendar, she accepted, the calendar is visible however, the color categories
    are not appearing.
    I've tried setting an appointment in the 2010 Outlook shared calendar with all the color categories in the list, then going to the client's 2007 Outlook and updating the color categories in her mailbox but nothing changes.
    I've read about 20-30 blogs, tech form and MS tech answers on this subject and I get conflicting solutions. One states that you can't transfer the master color category list, you have to change it on each Outlook client while others state the use of an appointment
    and upgrading the categories from the properties in the client's mailbox (which didn't work) or using a third party add-in to manage a "Master Color Category list" (which costs money). I would like a straight answer to my question, which is,
    "why can't the Outlook 2007 client see the color categories in the 2010 shared calendar?" and "How to I fix this?".
    This questions has been asked in so many different ways that I'm not sure if someone will help me without having to call MS support and pay for it. This has got to have a simple solution that I don't need to pay for it, yes?
    Anyone, please help me.....

    Hey mate i had the same issue and was dumb founded till i came up with a solution that worked for me, and possibly someone out there looking for the same solution. Half the info i looked up was all bullshit and took me months to come up with a fix as
    im busy with other priorities.
    still busy so ill be quick...and not gonna get too technical just gonna lay it all out in steps
    1. create a mail account in exchange eg.
    [email protected]
    2. log into the account through outlook and share the calendars you set up.
    3. go to the exchange management console on the 'server ' right click the created
    [email protected] mailbox > manage full access permissions> and start adding the users who need access. (only thing that worked for me)
    4. close and reopen outlook on the users computer and then you should see the colour co-ordinated catergories that you assigned for scheduling that they can all access and book appointments in a easy colour co-ordinated layout.
    if it dosent show up try - *on the users computer* start >run>cmd>gpupdate/force
    this will force the update on some computer that didnt show up with the effect. only had this problem with 1 user and this fixed it :)
    hopefully this idea helps you! as it did me cause no geek out there never gave me this easy fix option, instead right properties and blah blah blah technical crap that dosent work, wankers!
    thanks :) 
    P.S this worked between 2010 and 2007 microsoft outlook

  • Prevent MAC Mini from appearing on the shared network

    Hi,
    As above, how do I go about hidding the MAC Mini from appearing on the shared network which is able to seem by other? I had already disable the file sharing under the sharing? What I want to achieve is to totally prevent the MAC Mini from appearing on the shared network as the network I am connecting to is public network. Between I am runnning OS X.
    Thanks in advance!

    Hi,
    As far as I'm aware of you can't without disabling a couple of things that'll also prevent any internet usage, since it's all tied together now.

  • My wife has shared her calendars but they won't appear.

    My wife has shared her calendars with me and they show up on the side bar of the calendar as shared.  Her calendar items do not show up in my calendar.  I have "checked" the highlighted calendars I want to see on my calendars.  Mine show up but not the calendars she has shared. What am I doing wrong?

    Try this support article > iCloud: Share a calendar with others
    Might be a private or publc issue.

  • How do I get reminders to show up from Tasks I have created in a shared mailbox?

    I have tasks set in a shared mailbox.   They have reminders set in them.  I do not get the reminders.  Running Windows 7, Office 2010 Plus. 
    I have also tested this with meetings from the Shared Calendar and it does not work.
    Is there a setting that needs to be changed or something I can do to start getting these reminders, as well as the ones in my own mailbox?  Or even better have an automated e-mail sent to me when one of these tasks become due?

    I have found my way to this topic also through the outlook forum and am surprised that you guys are sending Gabe H back to the outlook forum once more... this looks to be a little bit like we users are dealing with a bureaucratic government desk?!?
    Anyways...
    In our office we have the same issue... reminders and notifications don't work from a shared calendar. Also, it is impossible for items in a shared calendar to appear in the "to do bar" in the email-viewpane. For that issue a ticket was created all
    the way back in 2010 on
    Shared calendar items in "to do bar"
    and users are still discussing and asking questions on it without any solution from you guys at Microsoft. Thats almost
    5 years without a solution. The two issues are clearly related and they exist at least since Office 2007 and still remain unsolved in Office 2013 which our office is using.
    Now... in stead of referring and rereferring this issue from forum to forum and refrain from answering at all on the other... maybe you could put your heads together, brains in gear, try to think out of the box for a change and help out all those millions
    of outlook users which would love to use shared calendars in the proper way.

  • Do Office365 shared mailboxes require an AD user?

    If you have the account disabled in AD and the shared mailbox is OK I'd say its probably OK to delete.
    Only catch may be that if you delete the AD user and you manage group membership on the AD side you'll no longer be able to nest the shared user in a group (because AD won't know anything about it).
    May well be a non issue for you but it did come up for us when someone asked if their team's shared mailbox could be added to a distribution group.  I've been keeping the "shared" users in their own OU, with a random strong password set that no one knows (not even me!).  Going forward I may try disabling them - I'm guessing the group membership will still sync through to 365, even for disabled members.

    Some mailboxes had been converted to shared ones already.  While removing the O365 license is ok, is it also ok to purge the on-prem AD user associated with that shared mailbox?  (They are currently set to disabled.)
    Thank you!

  • How can I add a SHARED Outlook Calendar to my iPhone?

    I have Outlook for work. I have my personal calendar on there, along with my work calendar which is shared with my boss. When I sync my IPhone to Exchange, my personal calendar from Outlook syncs to my phone. The Shared calendar does not appear, however.
    I don't want to use an app (I have OWA and hate it) and I want the shared cal to appear on my calendar in my phone. I also need to do so without adding my boss's email account to my phone. Help!

    Depending on the version of Exchange in your environment you need to verify with your Exchange Admin that iCal publishing is enabled (Exchange 2010 or 2013) then you could send an email with a link to the shared calendar then subscribe to
    it.  Below is a link on how send the link once it's enabled and one for your Exchange Admin on how to enable iCal.
    Send email to shared calendar:

    Enable iCal on Exchange 2010:

  • TS4118 How do I stop sharing my calendar with someone I now share it with?

    I do not know how to remove someone from sharing on of my calendars on my iphone 4.

    Stop sharing a calendar
    Click the Share button to the right of the calendar’s name.
    Do one or both of the following:
    Deselect the checkbox to the left of Private Calendar.
    Deselect the checkbox to the left of Public Calendar.
    Click OK, then click Stop Sharing in the dialog that appears.
    A private calendar becomes unavailable to all participants. A public calendar is removed from its URL and becomes unavailable.

  • Shared mailbox and personal mailbox showing identical content in Outlook

    I have one user on Outlook 2010 who has Full Access permissions to a shared mailbox. In OWA, everything looks fine, but in Outlook, the shared mailbox shows the contents of her personal mailbox instead of the content of the shared mailbox.
    If she views the shared mailbox's Inbox, it shows her the contents of her own Inbox instead of the shared mailbox. If she attempts to view the shared mailbox's Calendar, it shows her nothing at all. There are no error messages.
    I configured a separate Mail profile (via Control Panel) for the shared mailbox, and that works fine also.
    I deleted her Mail profile and all cached Outlook data, then created a new profile, and let Outlook recache all the data. Same problem.
    Any ideas what is going on or how to fix it?

    Finally some moderately helpful info:
    The end user logs into a computer on an untrusted, foreign AD domain (domain2.com) using an account from that domain. She then logs into her Exchange mailbox in Outlook using her domain.com account.
    Every domain2.com computer she logs into gives her the same random mailbox mirroring problem.
    I had her log into Outlook on a computer on domain.com located in my office and leave it running for 3 days. Every time her Outlook client on her regular computer would start or stop mirroring mailboxes, she would let me know, and I'd check the computer
    in my office and find no problem.
    So the problem is something in the foreign domain or something that that domain's administrators are doing to the computers. Unfortunately, several other people on that domain are using mailboxes and shared mailboxes on my Exchange servers in the exact same
    configuration and are not having this problem. It is only this one user.
    I am pretty sure they are not using roaming profiles. I know they are not using mandatory profiles.

  • From field in shared mailbox displays LegacyexchangeDN instead of person's email address.

    We have a situation where a group of users who utilize a shared mailbox are getting a weird issue from time to time.  They will take mail from their own mailbox and drag it to the shared mailbox.  Sometimes the email show up fine, other times the
    from field shows the GUID of the person's mailbox rather than their email address after they move it.  See attached pictures.  Any idea what would cause this and how I would fix it?  It appears this way in everyone's Outlook and OWA.  

    Hi,
    DisplayName is an Active Directory property which represents the display name of a recipient in an appropriate format to display to the end-user. This is a Unicode property which may contain non-ASCII characters so that a user name may contain DBCS characters.
    In your case, you need to create a registry entry on Outlook side.
    For more information, here is a helpful thread for your reference. (Note: Though it is Exchange 2010, it also replies to Exchange 2013 about this issue.)

  • 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.
