Moved shared mailbox (calendar) from Exchange 2007 to 2013, now it doesn't work.

We have a few mailboxes that are used for their calendars only so that staff on the road can update their whereabouts. This worked fine in Exchange 2007, but once I moved this mailbox to 2013, it stopped working. People can connect to the calendar, but it doesn't show any of the entries, except for a few recurring appointments.

At first I thought it had to do with the ActiveSync settings, so I changed it from the default of 10 users to 50 users via new-throttlingpolicy, but that didn't seem to work. (Granted, I didn't get a chance to restart IIS or such, so maybe all that's needed is that?)

Perhaps it's some other setting that needs to be changed?

I guess ultimately I should set this up differently as well (public folders?), so I"m open to suggestions here, assuming I can easily move over what's already in place.

any chance that the calendar entries are published as private meetings?

I've found issues viewing shared calendars when someone pops a private meeting onto a calendar and everyone else is viewing it by adding it as a secondary mailbox to their profile. View it directly it's ok, view it as a secondary all private are blank.

They're not private. Everyone can see the appointments fine if accessed via other methods, such as through Outlook or OWA. It's just with the phone that there's issues.
Eric WoodfordSoftware Systems Specialist 3Commented:
Just checking, because you said they can see some of the appointments but not all. I've seen more than my fair share of private meeting being invisible. I've gone as far as setting shared/resource calendar options to block booking private meetings.

Also missed that is was an activesync only issue. If so, I doubt Exchange 2013 public folders will resolve this issue for you. Most cell phones don't even know what a PF is, and in 2013, they look like mailboxes.

Device OS? iPhone/Android/WP/Palm?  each supports AS differently and you could get varying results. Using a 3rd party app may be your best solution.

Most of the phones we use are iPhone, but it's affecting all devices, including my Android.

Are the users with the devices still on 2007? Sometimes I have seen issues if a shared mailbox is moved to 2013 before the users that access it.
ruhkusAuthor Commented:
This is affecting all users, those on 2007 and those (most) on 2013.

As noted, I did update the throttling policy, but haven't restarted any services (I'm still actively moving mailboxes and didn't want to stop this process). I'm wondering if this could be the issue, although I see no mention of needing to do a restart.

I finally got it working. I needed to edit the RCAMaxConcurrency in the throttling policy, as opposed to the activesync settings, as I was initially doing.
