Outlook webpage refreshes whenever emails with attachments are opened or writing new emails

Just as the title says, this began for the first time this morning. My Outlook webpage will refresh within seconds of opening any emails with attachments or opening up a new email to write regardless of email account or browser. I've tried on Microsoft Edge, Firefox, and my main browser, Chrome, to no avail. Have not found any solutions including clearing browsing history/cache/cookies, disabling any and all extensions, and even removing extensions from my browser entirely. I've also reset my password twice, restarted my computer, and don't know what to do from here.

    This issue occurs when authentication partially times out, such as when an attachment is being fetched in the background and fails with a 440 error. The current workaround is to sign out and sign back into your Microsoft account.

    It’s frustrating that end-users constantly have to provide detailed instructions and reproduction steps when these issues should be identifiable within your code. It feels like all responsibility is shifted onto users while little effort is made on your end to proactively resolve them.

    Microsoft still struggles with proper session management. For example in Teams, even after a session has expired across all devices, users may still receive mobile notifications, even though re-authentication is required. An absolutely trash implementation.

    This issue seems to extend here as well. The session appears to be in a partially logged-in/logged-out state: you can browse and refresh your emails, but when attempting to open one and fetch an attachment, an error occurs. The Web App then attempts to resolve it by refreshing the page, assuming the sign-in page will appear if the session has expired.

    This is the workaround I've settled on:

    • Continue to use Chrome as my main browser
    • Use Firefox for email only
    • Every time this issue crops up (which it continues to do, even in Firefox), apply the short-term fix of clearing Firefox's cache & cookies. This way I don't have to deal with collateral damage to the rest of my browsing landscape, which is in Chrome.
    • Divest from MSFT

    I have two separate Chrome browsers running at once on the same laptop.

    One work email has this issue, the other work email is fine. (Two separate businesses.)

    Mine doesn't seem to care if there is an attachment or not. Reply/Reply All/Forward all cause an immediate refresh.

    Clearing my cache is the only thing that works and it only works for a day.

    Really hope this gets fixed soon because I can't keep wasting my time and my bosses time with all the multi-factor crap I have to do to sign back in every day.

    Apologies, I meant to reply to Yolanda.

    Thank you for the suggestion. Unfortunately, cleaning the cache, closing the browser, and rebooting my Mac did not resolve the issue.
