Reminder from already deleted calendar appointment keeps on popping up

  • Hi,

    since a few days, I have a reminder that pops up every couple of minutes in WebApp. This refers to a calendar appointment that I deleted more than a week ago.

    It does not let me finally close nor delete it.

    In addition, there are several task entries in the To-Do list that also refer to previously flagged messages that are already deleted.

    Hopefully, it is not a secondary effect of deleting or fixing several corrupt database entries as described here

    Maybe there is a possibility to fix these entries ?

    I am currently using core- together with webapp-

  • Oops, it happened again.

    Even after recreation of the database, there is a reminder that keeps on popping up for another item that has been deleted a couple of days ago.


  • We have seen this problem as well with Kopano 8.4, what I’m about to tell you doesn’t make a lot of sense to me but it appeared to work. After running kopano-fsck and working to delete the appointment out softdelete and make sure its truly gone it was still reappearing in both WebApp and Outlook. Doing an Outlook.exe /cleaneminders resolved the problem.

  • I had this problem too. Currently using

    Those reminders pop up in both Outlook as well as in WebApp. Opening the reminder then tells me the message (which probably means the calendar entry) does no longer exist or there are not sufficient rights to it. Checking the calendar for the date in question does not show the appointment for which the non-delete-able reminder pops up. It was really annoying :-)

    I ran kopano-fsck -u username --autofix yes --autodel yes --all
    And it did not fix the problem

    Then I ran:
    kopano-admin --purge-softdelete 0
    and now the defective reminder it seems to be gone (at least in WebApp - did not check Outlook yet!)…
    Lets hope it stays this way.

    WebApp gets which elements to remind about from a searchfolder, so rebuilding those could potentially help here as well:

    from man kopano-server

           --restart-searches, -R
               Rebuild all search folders. This may take some time and is only needed when your search folders have become out-of-sync with the actual data in the database. The sync will
               start synchronously at the start of the server, and you will have to wait for all searches to complete before connecting to the server.

    Since you mention outlook. If you are referring to the old Zarafa mapi client you could probably also fix this by opening outlook with the /cleanreminders switch. see for more information.

  • I had the same issue this morning. I got a reminder for an object which was deleted, but still in the softdelete folder. As a result, WebApp kept bugging me with a reminder which could not be closed, as the appointment was not in the calendar.

    Purging the softdelete fixed it.

    To me, this sounds like a bug: either there should be no reminder (because there is no appointment in the calender), or dismissing a reminder must look in the calender as well as in the softdelete area.

    Kopano Core: 8.5.4

  • Same problem today for one user. Purging the softdelete finally fixed it for me too.

    Kopano Core: 8.5.5

  • Have this too on 3 installations

    Kopano Core: 8.5.5

  • I also had this issue - running
    kopano-admin --purge-softdelete 1 -v
    fixed it :-)

  • @anotherandy

    but if running purge-softdelete the users are not able to restore items am i right ?


  • Hi,
    if I understand this here right:

    than there is no restore possible.

    But how exactly softdelete ist working - I am not sure, what you can see here:
    best regards

  • Hello together,

    if you delete an item, this item is not deleted for real but get the “softdelete-flag”. this is used to hide this item under the deleted path and show it under “restore items”.
    by default kopano-server is configured to harddelete all softdeleted items older than 30 days. After that you cant restore this item without having external backup or archiving. (wich is highly recommended and even more nessercary when looking at DSGVO etc., comeing this year)
    e.g. mariadb working with innodb wont free the physical disk space from disk, but will allocate new items etc. within this space.
    After deleteing a hugh ammount of items (had this case with over 1.9 mio elements) i cleaned up my db by using the command described later in the posted link from @AnotherAndy.
    the result was a cleaned up and much better performing db :)
    but be careful, you need the physical diskspace from the biggest table stored within your data directory additionaly on your disk.
    the sqlcheck will copy every table file per file and create a new one, replacing the current.


  • Good afternoon,

    Following problem:

    I have a reminder, I click “Dismiss” and I get:

    Cannot dismiss the reminder. You may be reminded again.

    This has happened only recently, I never had this issue before.

    The event was added to the calendar well after the upgrade of Kopano core and after the recent update of Webapp.

    Current versions:

    Kopano Core:

    If I click “Dismiss” or “Dismiss All” I get the error message and the event keeps coming up.

    I have tried with the old zarafa webaccess (which still runs on my server) and the reminder comes up but clicking “Dismiss” nothing happens and the event stays up.

    The event was created via z-push on my android phone.

    Manually deleting the event in the calendar didn’t solve the issue at all, although the event is gone in the calendar, reminders still come up.

    In the end the only way to fix it was to purge-softdelete with 0 as a parameter.

    Something is broken somewhere… Particularly as a number of people noticed it so far.

    Perhaps the latest version of z-push prod, not sure. This is the first time that I see this happening on my system.

  • As far as I can see it seems to be a privilege problem. I came across the same error when I deleted an event (and also when I changed another) on another user’s calendar. We have mutual mailbox access, but I never bothered with setting the correct privileges for me since I’m also administrator and the force is with me. After changing the privileges for the relevant items (set mailbox and calendar to “full access”, so no refined research for now) deleting an event on the other calendar worked as expected: No more reminder!

  • Second user with this problem.
    The reminder is comming every few seconds for an older element.

    There seams to be an issue with this.

  • @Jo-TL,

    which z-push version do you use - also 2.4.0?
    and from where did you create this calendar item?


  • Kopano

    This is a known issue in the 8.5 release of kopano and most likely linked to kc-1074. The latter has received a fix yesterday. After it has received some testing we are going to put out a new 8.5 update.

  • @andreas_mueller

    Mine wasn’t a cross user event. It was something that I created myself in my own inbox just a couple of days earlier and then the problem occurred.
