Certificate Error
Couple of my users are receiving this error for outlook.office365.com in Outlook 2010. Any ideas?

We have a couple of clients with this error. They have two different Internet Service PRoviders, one active and one of backup. Booth customers had the same ISP active, we change to the backup ISP for all out connections.
We check DNS, SPN, outlook´s updates, etc..
The issue was fixed changing the ISP .
Greats
