My client has been using Office 365 since early 2012. They have an internal SMTP Service running on a server which their MFP devices use internally to allow the users to scan to email. Setup in the correct manner (IIS 6 SMTP Service with relay to Office 365 configured over port 587 and using a fully licenses Office 365 user).
It’s been working fine until about a month ago users started to report delays in receiving their scans. It used to take 1-3 minutes depending on the size of the scan but not even a one page 30KB scan can take up to 30 minutes to each the user.
Nothing has change on the clients side in the last 6 months (I know for fact as all changes come through me).
Wondered if anyone else has come access this?
