I had to download the authentication app for my work. Since doing that I cannot access any email I received prior to the new app. I am getting new email, but I need access to the old ones

    Hi @Angela ,

    Does this problem occur in Outlook desktop client? If so, it is recommended that you create a new profile and re-add your account and check your email sync settings.

    To check the Outlook cached mode time, you can follow these steps:

    • Click File > Account Settings > Account Settings.
    • Select an Exchange or Microsoft 365 account, and then click Change.
    • Under Offline Settings, move the slider to the desired amount of time.

    Besides, log in to the web version to check whether this problem exists.

    If the issue occurs in outlook for mobile, please kindly understand that here we mainly focus on general issues about Outlook desktop client and know little about Outlook for mobile. So, in order to better solve your issue, it is suggested for you to try contacting the in-app support (see Get in-app help for Outlook for iOS and Android) or post a new thread to the dedicated forum for Outlook for mobile.
