How to unblock third party apps on mobile phone through Exchange 2010

Tim asked
Last Modified: 2017-06-20
Recently we migrated from Exchange 2003 to Exchange 2010. I have moved my mailbox from 2003 to 2010 about a week ago but yesterday my phone as well as my bosses phone all lost their third party apps. When I go to Google Play store it shows that I have the applications but they are disabled. When I try to enable nothing happens. I think this is a symptom of this new exchange server however when I go to Active Sync there are no settings stating that third party apps should be blocked or at least I don't see it. In any case both phones cannot access any third party apps and if we start moving more users to this server I am afraid they will lose all their apps as well.

How do I fix this. I am at the point of putting my phone back to factory settings but in doing so will erase everything on my phone and I don't want to do that yet.

I don't see this issue related to Exchange. Exchange doesn't have such feature to remove 3rd party application in your mobile. It could be some other application, which could be doing it. Try to reset one phone and check the result.

When I add the email to my phone it tells me that exchange has to control some of my security features and that is why I think it did this plus my boss had the same issue occur to his phone and he has a different phone than me.

When you stood up your new exchange environment did you do any active-sync policies or just enabled it?

Take a look here to see the policies that you can enable and control:

I just enabled it however we do have a consultant working for us that knows more about Exchange 2010 and might have enabled some policy that did that. When I look at the ActiveSync tab is just shows the default policy which shows no security applied to the phones however after doing some testing found out that Exchange is making these changes. My boss was doing some testing and found a security setting on his phone where Exchange controls phone security which he turned off and all this third part apps became available but lost his ability to sync with email and his calendar. Then when he re-added the account to his phone it pushed down the security settings again and he lost all his third party apps. Do I need to make a new policy then apply the security settings? Is so what settings do I need to activate so that it does not block third-party apps?

You can create a new policy and only configure the policies that you want like timeout, passcode etc and then apply it to your phone.

I would also talk to your consultant to see what he is doing in the backend

This solution proved to be the best solution due to the mail client on the andriod phone and working with the new Exchange 2010 server would erase all third party apps no matter what policies I set on the new exchange server.
