mail fetching stop working

Question

Hi all,

We have project that is set to fetch emails from our on prem Exchange server. Everything worked fine until Saturday when it stoped with error:

Unable to find valid certification path to requested target

We are using Exchange on prem with enabled IMAPS protocol. Certificate for IMAPS is issued by corporate CA.

Once again, everything worked fine until last Saturday.

Any help here pleas, it is pretty urgent.

Hi Jack,

Thanks for response. It looks like certificate issue, that is true. But it just starts over the weekend. Worked fine for couple months. I am not sure if anything changed in this cloud edition during weekend.

This seems like a certificate issue. Here is an old thread that may provide some insight. If not you might contact Support directly or contact you IT group to check the certificate.
