Outlook emails not sending (Error code: 0x80070005-0x000004dc-0x00000524)
Hi Lisa! Thank you for the idea! Unfortunately, that is not it either. It happens when sending to individuals, groups, even myself. I have tried the removing of auto-complete options and it does not change the issue. :(
How many people are you sending this email to at one time? There are limits, so maybe that's one of the issues.
Thank you for the additional tip. Unfortunately, that's not it either though. It happens when just sending to one person (incl. myself), as well as with any other number of people on the email. :(
Ok well now it's down to what's going on with the computer.
Antivirus? What product do you have? If free McAfee, Avast, Avira...those are culprits. Paid can cause Outlook issues as well.
What version of Outlook? Product? Subscription?
Windows updates. Have you completely updated?
Firewall?
VPN?
Thank you for continuing to support me here!
Windows 11 and it's up-to-date, M365 Family subscription (and office is up to date). Using Windows Defender firewall and Windows Security for antivirus (no 3rd party products). No active VPN. ...and no major changes lately on any of it either. I am really stuck.
Note: problem does not persist in OWA or Outlook mobile (iOS)...just the Windows client.
