Outlook does not reconnect after waking from sleep mode

Hi,

When I leave my computer idle so it enters sleep mode outlook does not reconnect to server and cannot update the latest emails. Closing the program down and starting again means that outlook will not even open. The only way I can get outlook to open up again properly is to restart the PC.

Is there a better fix than this, as it is rather annoying than to have to restart all the time.

I can confirm I have the latest updates for windows 11 and Microsoft office programs.

Thanks

Thanks so much for involving yourself in this craziness. I appreciate it, and I appreciate you.

While I am a Dell user (XPS 15 9570), I don't run ExpresConnect. I hope those who do will find your tack useful and effective.

Again, thank you. I promise to share whatever I find out here.

    It seems that the fix in my case ended up being removing other versions.

    There were 4 versions installed:

    • Microsoft 365 en-us
    • Microsoft 365 es-es
    • Microsoft 365 fr-fr
    • Microsoft 365 for enterprise en-us

    I removed all but the for enterprise version and ran a quick repair on enterprise and this seems to have worked.

    At first we thought it was a sleep issue but it happened once when a user was still active. Hopefully this fix works for more of you. Fwiw our systems are deployed via intune autopilot so I'm not sure if someone screwed up on the deployment and pushed multiple versions

    I have the same issue. It's becoming progressively worse and more frequent.

    I will try the two solutions suggested above by you and Jim_111.

    Fingers crossed Microsoft can resolve this so we all stop being so disrupted by it.

    I have been troubleshooting this as a license issue as our group uses individual licenses, based on email addresses. I used the steps below to strip out license information from the Office product and it will prompt for re-licensing information upon opening Outlook. It has helped in several instances.

    1. Reset the Office activation state.  So, it clears all credentials.

    https://learn.microsoft.com/en-us/office/troubleshoot/activation/reset-office-365-proplus-activation-state

    Download the UI Version and run it – this will clear out the licensing information for the product

    1. Before opening any office product, add the following registry keys:

    To resolve this issue, use one of the following methods.

    Use ExcludeLastKnownGoodUrl to prevent Outlook from using the last known good AutoDiscover URL

    Configure one of the following registry subkeys as follows:

    HKEY_CURRENT_USER\Software\Microsoft\Office<x.0>\Outlook\Autodiscover
    DWORD: ExcludeLastKnownGoodUrl Value: 1

    HKEY_CURRENT_USER\Software\Policies\Microsoft\Office<x.0>\Outlook\Autodiscover
    DWORD: ExcludeLastKnownGoodUrl Value: 1

    1. Open Outlook and authenticate to re-license the Office applications

    I fixed mine by disabling my hyper-v network adapters. I had noticed Windows network awareness thought I was not connected after sleeping even though I was on the internet. Disabled the hyper-v nics and networks in settings showed me connected after without rebooting then Outlook connected.

    Does this issue remain fixed for you? And did you only disable the Hyper-V network adapters or did you remove Hyper-V completely?

    Does anyone else have any other comments on fixes that worked? I have two users both have issues with Outlook and Teams after being idle for a while.
