I'm trying to get a remote user setup with emails from exchange. He is outside our normal ecosystem and just using the Windows 10 Mail app to connect to Exchange 2016.
It's all up and running fine, however it is only syncing emails from the last month. When looking in the Sync Options, under "Download email from" the longest option is "the last month", however other gmail/hotmail accounts have an option for "any time"?
Any ideas on how to get the "any time" option within the Mail app?
