Users see a different calendar than the user itself sees

Hi,

Today I ran into a strange problem. Users have added user X's calendar using the GAL, however the calendar that they see does not match the calendar that user X sees in his Outlook our Webmail.

When troubleshooting, I gave myself permissions to the user's mailbox. After I've did that the calendar matches what user X sees himself. After removing the permissions, I saw the same again as everyone else in the organization.

I have no idea where to look next. It think that user X has created a new agenda and has removed the default agenda, but I can't find it anywhere. Where does the calendar in the GAL come from and how do I check that?

Hopefully one of you can help me!

Hi,

Thanks for the tip. I ran this one, but all values ​​were correct and there was no calendar anywhere else. The problem has now been resolved.

The solution:
I have reset the permissions from the calendar for the whole organization. After changing those permissions, the correct calendar was visible.

My guess is that there was a synchronization problem somewhere. Who will say.

Thanks for thinking along!

Hi @DylanHanssen-3657,

Users have added user X's calendar using the GAL, however the calendar that they see does not match the calendar that user X sees in his Outlook our Webmail

The calendar added via GAL is the default calendar of the user. So agree with the assumption you mentioned that the calendar which user X sees is a different calendar created by himself/herself, rather than the primary calendar of the mailbox.

Normally, we are not able to delete the default calendar, the "delete calendar" option is grayed out for the primary calendar:

But by "can't find it anywhere", do you mean you cannot see the default calendar even when you are granted permissions to user X's mailbox? How about user X himself/herself, can he/she see the default calendar that the others users see?

If the the mysterious is not visible anywhere, I'd recommend trying to connect to Exchange Online powershell(assuming the mailbox is hosted in exchange online as noticed you are using the Exchange online related tag), then run the command below to see if you can see the calendar folder:

 Get-MailboxFolderStatistics -Identity UserX | Select FolderPath

Hi,

Thank you for your answer.

As you also indicated, the option to delete the calendar is grayed out for user X. The calendar that user X sees is different from the default calendar in the GAL. However, I cannot find another calendar within Outlook as you can see in the picture below. The strange thing also is that the name is "calendar 1 - ..." as I stated before the gives me the inpression that is is not the default calendar.

Running the cmdlet specifies that there is only a \\calendar folderpath and no other.

Thanks in advance.

Hi @DylanHanssen-3657,

Yes, this doesn't look like a default calendar.

Also from the screenshot you shared, user X is using a different display language from English, right? If there are other users using the same language as user X, would you mind checking the display name of their default calendar, is it "Calendar" or "Agenda"?

Furthermore, I’d suggest downloading and extract the MFCMAPI tool on user X's machine, then follow the steps in the document below to see if a default calendar folder can be found using the tool. If it's indeed listed there, make sure the PR_ATTR_HIDDEN property of the folder is set to false:
Default folder is missing in Outlook and Outlook on the web
