How I can switch from working offline to working online in outlook?

I have this same problem and unable to fix. Were you able to get a response as to how to repair. Thank you

I'm unable to connect to working on line. I have followed previous messages. Outlook is off line clicked to try and work on line to get messages but still not working. I hit send and receive and still stuck offine. Therefore not updating emails. At first it disconnected from WIFI then once connected will not work on line. Is there someone that can help?

Thank you so frustrated

The online/offline radio button does not work in my Outlook from Office 2021. All my email *.ost files are on my local drive. Surely there is a way to log into either the Live account or the web Outlook account & change to online from there. If there isn't, & I'm yet to fine it, then why not. It's a failure on Microsoft's part for not having some sort of alternate way of changing from online to offline & back.

My question is this. Can I uninstall/reinstall Office 2021 & re-create my email accounts, a mixture of Outlook & Gmail accounts, & not lose any emails? More importantly, will this fix the offline issue?

Kind regards, Ian

I had this problem with being stuck in Offline mode. I followed the instructions above and they did not work - no amount of clicking on the Offline button in send/receive would change my email to Online.

I went to File/Account Settings/Repair, clicked, and then received my mail.

The Work Offline button in Send/Receive is very problematic - it button is always a globe with a red x, even if you're actually working Online and you cannot click to get a drop down menu for the preferences.

The work offline button always has a red x. When active, the button has an outline and turns grey as shown in the screen shot below:
