Outlook.com account can't send

jeffj · August 7, 2024, 6:08pm

Have been running version 10 for a while. No problems after update - until recently. For the last few days, I have been unable to send email with my outlook.com account. Can still receive emails and calendar syncs OK.

Sent messages never leave the outbox. On each connection attempt, even when there is no message to send, there is a message like this in the log:

11:05:05 AM [email protected] [AirSync] MailClient.Accounts.ConnectionException: Found invalid data while decoding.

Any idea? Is this affecting more than me? Has happened with both the previous update and the current one (3447) - I did an update to see if that would fix it. No luck.

Have been running version 10 for a while. No problems after update - until recently. For the last few days, I have been unable to send email with my outlook.com account. Can still receive emails and calendar syncs OK.

As it’s been a few days and you are still getting sending mail problems with your Outlook.com account even with the latest V10.0.3447 release, then i would suggest doing either of the following.

1). If you have been making regular eM Client V10 backups prior to the update when it was working ok, then suggest to try restoring a recent dated backup via “Menu / File / Restore” and any new Outlook.com emails since the restore point will update when eM Client syncs.

2). If you don’t have any recent eM Client backups and you have only IMAP, Exchange, Office 365, or iCloud (Non POP) accounts and “nothing in Local folders at the bottom left”, then suggest to just remove and readd your Outlook account via the automatic account wizard via “Menu / Accounts”.

Check (after the account is resetup) in the “General Tab” of your Outlook account under “Services” near the bottom, that “AirSync” is still enabled. Then save accounts and try sending mail again.

If you then still have the same sending issues, other things that can sometimes affect outgoing mail is eg: Optionally installed Firewall Security Programs, or Optionally installed Antivirus programs or VPNs. So if you have anything like that installed “other than what comes default with the OS”, try completely disabling those to test.

Apart from that there could be a possible actual Outlook SMTP current server technical problem affecting where you send through from your country. Those sort of things usually resolve within a day or so, so it’s not likely it’s a Server problem.

Removing and recreating the account seems to have worked - can send now, and clean logs. Wonder what was messed up before? I did notice that it asked for additional permissions from live.com again.

V10 required “reauthorization after upgrade” as in a blog I read on the upgrade, where a browser window normally appears to click allow etc, so at a guess could that part then didn’t reauthorize 100% for some reason and then had the sending problem. So good it’s now sending mail ok now.
