E-Mail Notification not working anymore (Office 365)

Added by Mark Renton 12 months ago

Hi,

since about 2 weeks, the E-Mail Notifications doesn't work anymore. I am using Redmine 3.4.3 and the SMTP Office 365 Server. I haven't made any changes in the configuration, before it has been wokring fine.
Could it be related to this:

What TLS Version is used for Redmine?

Thank for your help!
