I was unable to send emails for an outlook.com account. When trying to send an email, it would indefinitely get stuck in the eM Client Outbox.
In addition, when going to the Calendar or Contacts pages, a red warning triangle with an exclamation mark would appear next to the outlook.com account name. Clicking on the red triangle did not resolve the issue.
After removing the outlook.com account from eM Client and re-adding the account, it has started working OK again. Therefore I’m reporting this for information only.
System Information:
eM Client - 10.0.3447 (d250ce6)
Windows 11 - 23H2 (22631.3880)
