Hi,

I have one calendar event that I tin can't delete.

What I have tried:

Delete through Outlook, get error ''the client functioning failed''
Delete through OWA --> tin delete, but when refresh the page it comes back.
Delete using the search-mailbox powershell command (search-mailbox -identity <mailbox> -searchquery 'Field of study:"Subject"' -Deletecontent)
Delete using the remove calendarevent powershell command (remove-calendarevents -identity <mailbox> -cancelorganizedmeetings -querystartdate "v/26/2021" -querywindowindays 1)

I tin't open up the calendar outcome, get the following fault --> there is currently a problem opening item. this may be temporary, but if it happens over again, you lot may need to restart outlook. the client performance failed

The irritating function is that ever a calender event reminder pops up in outlook.

Can someone help me aid in this?
thanks in advance.

Answer 1

Unfortunately that doesn't help.

All steps done, all the same result, exept step 6.
When step 6 is executed, the event will be removed from the local outlook client, when i accept enabled cache mode.
Notwithstanding, that modify never get synced with exchange, i still see the same outcome in OWA.
Fifty-fifty later doing step half dozen, my outlook profile keeps crashing, can't open my mailbox on any client anymore.

Correction, can open my outlook profile

Accept you created a new Outlook contour? Is the item all the same there after that? (Check OWA again and try to delete it if so)

How-do-you-do @j586-7834 ,

Could it be canceled by the organizer if it's a meeting event?
Does this issue only occur on specific user? If and so, delight try disable calendar repair and so endeavour deleting the outcome.

                                      Fix-Mailbox -Identity <mailbox> -CalendarRepairDisabled $truthful

In addition to the methods provided by Andy and AlexC, I think you could also try moving this problematic user to some other database or import this mailbox to another business relationship to test.

As y'all couldn't delete it on OWA, I suspect this could be a server side error or the mailbox itself.

Answer 3

As information technology turns out, I am able to open the calendar event when I use enshroud manner.
I tin can also delete the calendar event from outlook, but that never gets synced to exchange, because information technology keeps present in OWA.

When I employ exchange online, I'm not able to open the event at all.

Unfortunately I tried creating a new outlook profile, didn't work.
also tried outlook.exe /cleanreminders --> nil changes

Set-Mailbox -Identity <mailbox> -CalendarRepairDisabled $true --> Unfortunately also no alter

I only received a message that another user has the same problem, so I have two users with this problem.
I got this trouble likewise on a test account of me, just past accepting the calendar invite that doesn't want to be removed from the fist user. (it's the same calendar event)

I'm currently looking how to calendar effect menstruation has happened with the user.

If yous need more info, feel free to inquire.

Answer 4

I accept looked a little deeper into it and it looks like the meeting was created from a shared mailbox, and the users where invited.
Yet, when looking at the event in the shared mailbox, I see that it is an appointment with no members.

I used the following command to get more info about the calendar effect: get-calendardiagnosticobjects -identity <mailbox> -subject "<subject field>"

Below is the data about the calendar effect of a detail user:

Hither is the information from the same calendar event now from the shared mailbox

Afterward doing this, I noticed that the outcome is deleted from the shared mailbox. I don't know if a user did this on coincidence. --> turns out the user deleted the upshot on the shared mailbox.

Hi @j586-7834 ,

I noticed the create time of this issue is 3/xvi/2021, and last modified time 3/10/2021 with LogTriggerAction: Create, which is to say the event was created on 3/10/2021, and no inverse has been made by now.

I think you could run the remove-calendarevents with -QueryStartDate 3/16/2021 to test.

Hi @ZhengqiLou-MSFT ,

Meet the answers to your questions below:

Equally y'all said, y'all deleted this event from your shared mailbox. Could it be canceled by the host?

the issue was created on the shared mailbox, and there it is deleted, I can't abolish the event, because I see the event simply on the detail user where I can't fifty-fifty open the issue.

Are there any users using the third-party mail clients with your shared mailbox? Such as gmail or hotmail?

I don't know exactly, but it is certainly possible they take connected the shared mailbox on other devices such as mobile.

And could you see this event in your shared mailbox using MFCMAPI?

Using MFCMAPI I tin't see the calendar event, thats probably considering the outcome was already deleted from the shared mailbox.

Is there a manner to delete this detail calendar event from exchange, even bij powershell or another script?

Thanks for all your help so far
