Relevant Product: Exclaimer Cloud - Signatures for Office 365
You receive an alert similar to this from Microsoft:
"Mail flow connectors rely on valid certificates for authentication and attribution. If you let one of your certificates expire, mail flow could be disrupted, depending on how you have configured your connectors. Please renew any expiring certificates to avoid this."
What does this mean?
This message refers to the certificate used to securely route your emails back from Exclaimer Cloud to your Microsoft 365 tenancy.
Exclaimer Cloud automatically renews your certificate 14 days before it expires; however, Microsoft may send you an alert up to 30 days before your certificate expires.
What do I need to do?
Since the certificate is automatically renewed by Exclaimer Cloud, no action is required from you.
You can safely ignore these alerts.
