Dear Community,
our users are getting this error message, while trying to open a specific shared mailbox via OWA > open another mailbox...
Error Message:

I already checked the permissions. All users have full access permissions for this shared mailbox. All users are licensed via Office 365 E3 License and OWA is enabled.
I even tested two Browsers (Chrome and Edge) on different computers with different users > error message shows up on every computer. I even cleared cache and everything but nothing changed.
Thanks in advance for your help :) Tell me if you need more information and I'll try to provide :)

Hi @Hülya Fidan
Welcome to our forum!
For better research, I would like to know how long this issue has been happening?
Is the error code the same for all users?
Can you provide a screenshot of this error? Please be careful to hide your private information.
Hi @Hülya Fidan
Haven't received your message for a long time.
Do you have any further issue on this topic?

Hi Hülya,
I suggest you run the following cmdlet Get-CASMailbox MailboxName | fl Name,OWAEnabled in Exchange Powershell to check if OWA is enabled for the shared mailbox.
Also try to access the shared mailbox in Outlook Web by Adding Shared Folder to see if it works.
Thank you for the answer I found out that somehow outlook on web was deactivated I didn't see it the first time last week, but today as I looked at the mailbox in the exchange admin centre again I saw that owa was disabled > so I enabled outlook on web and I'll test tomorrow again
Hi @Hülya Fidan
Is there any update on this case?
Please feel free to drop us a note if there is any update.
Hi @SokiGuo-MSFT ,
sorry for my late response I wasn't around that's why I didn't see your response. The issue is known and happening since 16.05.2024. The error code is the same for all users. One of the users told me he only has issues with this one shared mailbox. With another shared mailbox there are no problems.
Thank you for your response!
