Segmented GAL and Office 365

[clareq]

I have successfully created a segmented GAL, so students can no longer see all the mailing lists we don't want them to see. This has worked well in testing, so I've rolled it out to all students and staff. We are now seeing some instances where the new OAB isn't autoupdating. Staff have access to Outlook, and so can go to Send and Receive - send and receive All and the OAB updates. Students only have access to outlook on-line, and some can no longer type a name into the To field and find a staff member's address. If they go into the Directory, and the Staff address list, the staff member is there. Other students see exactly the same in the Directory, but the address autofills for them. How can the affected students update their OAB?

Anyone?

When I rolled out the separate GAL's and then updated them, I had to reset all the students back to the default GAL and back to the custom one the following day. The OAB only generally updates overnight in Office 365.

As it's only a few students, I'll try resetting them - thanks.
