Hello, I’m Virginia a fellow Outlook user.

Have you tried deleting the account & adding it again?

Is the app/program running the latest version? How old is the app/program?

Is the Mac OS up to date/running the latest version? How old is the Mac?

Please check the suggestions here for that error message:

Check the webmail version of Outlook to see if anything is showing in the outbox which hasn’t synced to the app.

If clearing the cache doesn’t help then try checking the disk for errors or try uninstalling & reinstalling the Outlook app.

I would try adding the account to the default/inbuilt email app to see if the problem occurs there too, if an email shows then are you using any adblocker &/or VPN which may be interfering with sync?

All you should need to do is enter the username & password & Outlook will fill in the details - is this not happening? Can you choose the email provider - Outlook/Hotmail etc?

When you enter the details is there a manual option after the two choices?

Have you tried adding the account to the inbuilt email client?

Hi Virginia,

Many thanks for the Message. I am running Outlook 16.110.2 on Tahoe 26.5.2 on a MacBook Air M1 2020.

I have checked the Webmail and Outlook and there are no unsent messages !!!Never had an issue before. I run Mail on both an iPhone & iPad with the same account and have no issues so guess it is an Outlook problem. Reluctant to delete and reinstall account as I do not want to lose any mails

I’m sorry to see that you’ve marked my reply as not helpful. Please note we’re not Microsoft but fellow Windows users like yourself & as we cannot see the problem/s first-hand we can only make suggestions for you to try which may or may not work.

If the account is set up as IMAP then the emails remain on the server until deleted from the app, however if you prefer not to do this then please try the instructions in those links as well as adding the account to the inbuilt email app, if the problem doesn’t occur then it is an Outlook problem imo.

What happens when you follow the suggestion to just enter your username & password or choose the email provider? Is there any error message?

Have you tried adding the account to the inbuilt email client rather than the Outlook app?

As you have posted in the Outlook legacy community then this suggest your Outlook is too old, in this case you can use a more modern email client like Thunderbird.

I have tried to add an IMAP/POP account. I finds all the details and displays them correctly but the "Add Account" button does not function

Try either just adding your email address & password & allowing the app to add the server details or choose Outlook/Hotmail from the list.

Is 2 factor authentication active on the account? If yes then when entering the details are you being taken to your account online to verify adding the email? If not then try creating an app specific password - log into your account & go to Security>Manage how I sign in>scroll down to App passwords>Create a new password.

Many thanks where do I find the "inbuilt email client"?

There should be an email icon for the inbuilt email app (icon has a pale blue envelope on a sky blue background), if not the search for it, if nothing is found then you may need to download it from the Apple App Store. If you still cannot use this then the third party option is the only option & has worked for other users when they cannot add/use their MS email in Outlook or their inbuilt email client.
