New outlook update not accessing account

Geoff Naumann 20

An auto update of outlook occurred yesterday on MacBook. I’m using sequoia is 15.8. On opening outlook I have a blank Microsoft screen. When I try to add email account I revive a ‘not online’ message. When I try to click to login it uploads a marketing screen to sell 365 and I cannot go further. ??? Thanks

Try these checks in order:

Verify Outlook is not offline. On the Outlook menu, make sure Work Offline is not checked. If it is checked, click it to go back online.

Confirm the Mac has network access. Open a web browser and verify that websites load. If the Mac is not connected, Outlook for Mac can show a not online message.

This did not assist. WorkOffline IS ticked but is grey. I cannot access it.

That sounds like a recent bug in Outlook for Mac 16.113

Prompted for a Microsoft 365 subscription
Can not switch out of Legacy mode
Outlook stuck offline

Fixed in the latest release - Version 16.113.1 (26091740) from the App Store.

Welcome Geoff Naumann,

Thank you for the additional information. Since Outlook is showing a blank Microsoft screen, reports that you are "not online," and the "Work Offline" option is checked but grayed out, I'd like to gather a bit more information while also trying a couple of quick checks.

Can you confirm whether your Mac can access Microsoft websites in Safari, such as: https://outlook.live.com/ or Microsoft Account?
Are you able to sign in to your email account through Outlook on the web, or does the issue only occur in the Outlook app?
Please completely quit Outlook, then restart your Mac and test Outlook again.
If the issue persists, try starting Outlook while your Mac is connected to a different network (for example, a mobile hotspot) to rule out a connection-related issue.

Looking forward to your update.

Hello. Thx for the contact. Yes I can access safari. Yes I can sign in to outlook on safari. I actually removed the outlook app and reloaded it, so it’s new and updated. I have ensured Mac was all updated and rebooted. All other ‘connections’ to server are functioning. ??? Many thanks Geoff

Hello Geoff Naumann,

Thank you for the update. Since Outlook on the web works and you've already reinstalled Outlook, please try one additional test:

Create a new macOS user account

Sign in to the new account

Install/open Outlook and add your Outlook account

Hello Emma. Others in the web community had similar issues. Someone pointed me to a further update 16.113.1 which corrects the auto update 16.113 so I am now operating Outlook again, the older version. Hopefully Microsoft will continue to test before releasing updates. Thanks for your contact, Geoff
