Hello, For the past few days, I have received a “500, Internal Server Error“ message (that I have listed in my Subject Heading).  I have attached four sequential error message details for you.   I hope that you can help me. Sincerely,  

Bruce Glazer 

My own appointments are viewed as external appointments in the app after being entered in Outlook on my laptop and then synchronized on my smartphone. Although I don't invite anyone to the appointments and only use them as reminders for myself. I can then falsely confirm or reject them. If I do this, the app returns problems. When I enter the same appointments directly in the app it works perfectly normal. I recently added a new calendar to one of my synronized accounts and since then I am experiencing this problem.

I am using version 5.6.0 (400201) on a Samsung

Prima Kalender aber leider kann man keine Aufgaben erstellen!

Je suis connecté avec mon compte apple et j'ai un compte onecalendar pro. Aujourd'hui j'ai ajouté un événement sur mon Iphone et un sur mon ordinateur(Windows) et ca ne s'est pas synchronisé ni d'un côté ni de l'autre.

When opening an appointment's details window, I can't change the size of the window. I put a lot of details in my "description" box, and it's super small in the window that opens.

During the sync. proces this message appears:

unique constraint failed ciexpanded_data.uniquemodelid

Since a couple of weeks i got a sync issue with an outlook calendar. All items (as far as i can see) do sync however after a while a sync / constraint error is reported.

Reinstalling the app does not solve the issue, also no issues appear with other mailboxes.

Any idea what is causing it or more importantly how i can resolve it. 

Thanks in advance for your support!

Best regards,

Albert

I am assuming this error is related to the sync problem that Microsoft created on 3/8/23. The content of the error is below. Any help is appreciated if this is an unrelated event.
