When users try adding their email accounts to Pipedrive using the exact same Exchange settings as work for other programs (such as Windows Mail and the built-in mail in iPhones), they get an error saying "We are unable to connect to your mail server. Please check your email address and password."
Other devices, clients or applications capable of Exchange ActiveSync or SyncML synchronization are not supported by Traveler at this time. On Android, in particular, only the Verse Mobile application is supported. The HCL Traveler team continually evaluates additional devices and applications for potential support in future releases.
