We have our exchange 2010 setup in a hybrid configuration with o365. I have a number of users with on prem primary mailboxes and an online archive in o365. The first time they connect to their online archive through outlook they are prompted for their password, if they check the save password box it doesn't ask again.
We have dirsync and ADFS setup, this is happening on both office 2010 and 2013.
But when they change their password, it seems like they are prompted for days even when clicking save password before it stops prompting them. Anyone else having this issues? We have multiple domains but only one forest. I was thinking it maybe replication if it was only for a few hours, but its days.
