    Do I understand correctly?

    From the Classic Outlook main menu, if you switch to the Send/Receive tab and click on the "Work Offline" button, it does not change from a grey background to a white background.

    In classic Outlook, a greyed or stuck Work Offline state usually means Outlook is not reconnecting properly, or the Send/Receive ribbon control is not behaving normally.

    Try these steps in order:

    1. Check the status bar at the bottom of Outlook
      • If it shows Working Offline, Disconnected, or Trying to connect…, Outlook is not connected to the mail server.
    2. Try toggling Work Offline again
      • Go to Send/Receive > Work Offline.
      • If the button background is shaded, Outlook is offline.
      • If the status still shows Working Offline, select Work Offline again until the status changes back to connected.
    3. Confirm internet and mailbox access outside Outlook
      • Open a browser and confirm internet access.
      • Sign in to the mailbox on the provider’s website and test sending/receiving there.
      • If mail works on the website, the issue is in the Outlook client rather than the mailbox service.
    4. Check whether the Send/Receive ribbon needs to be reset
      • If the Work Offline option is missing or not usable, right-click the ribbon.
      • Select Customize Ribbon.
      • Go to Main Tabs > Send/Receive > Reset.
      • Then test Send/Receive > Work Offline again.
    5. Install Outlook updates
      • Install any available Office/Outlook updates, then restart Outlook and test again.
    6. Create a new Outlook profile
      • A damaged profile can keep Outlook disconnected.
      • Create a new profile, open Outlook with it, and test the account there.
      • If the new profile still shows disconnected, remove the account and add it again.
    7. Test Outlook in Safe Mode
      • If Outlook connects in Safe Mode, an add-in may be interfering.
      • This is especially useful when the offline state appears stuck even though internet and webmail work.

    Important note:

    • If Outlook was offline while items were deleted or moved, some deleted items can reappear after Outlook reconnects. That behavior is expected during resync.
