    Hello Evaline Liu

    From the screenshot, Outlook on the web is returning:

    outlook.office.com can't currently handle this request

    HTTP ERROR 500

    An HTTP 500 error is typically a server-side error, meaning Outlook successfully received the request but encountered a problem while processing it.

    First, I have a few questions to help narrow down the issue:

    • Is this a personal Microsoft account (Outlook.com/Hotmail/Live) or a work or school account? If the account belongs to an organization, is anyone else in the organization experiencing the same issue?
    • Can you sign in successfully and access other Microsoft 365 apps (Excel, Word, PowerPoint, etc.)?
    • Have you been able to use Outlook on the web with this account before, or is this the first time?

    In the meantime, you can try a few simple troubleshooting steps yourself:

    1/ Try Outlook in a private/incognito window

    User's image

    2/ You can also try using a different browser, such as Microsoft Edge, instead of your current browser to see whether the issue persists.

    I look forward to hearing from you again.

    Kind regards,
