iPhone won't download from Exchange

Dashrender

I had a user bring me their new phone today tell me they weren't getting any email and their contacts and calendar wasn't syncing.

So I deleted the connection to Exchange and re set it up. Two hours later same problem. It never synced.

I found these directions online and thought I would share

Deleted the Exchange account from the device (iPhone)
Deleted the ActiveSync object from the users Active Directory user object (will need to be done by your IT Department)

In Active Directory Users and Computers
A. View --> Check: Users, Contacts, Groups and Computers as Containers
B. Find the user account and expand the container
C. Delete the ActiveSync object linked to the user

Re-added the Exchange mail account to the device (iPhone)

But did they work?

Dashrender

Yes, removing all the entries there then re-adding the phone worked.

That makes sense. Thanks for posting the directions!

This makes me wonder if there is a limit to the number of devices you can attach to an Exchange account?

Probably a practical number, but I doubt that there is a hard one.

I wish I would have noted how many that user had. They had at least 6, maybe more.

That is not so high that I would expect a problem. I've probably had nearly six.

It can be, but you have to change the throttling policy.

By default, the maximum is set to 10.

LOL, thanks, you gave me the exact result my post of 20 was wanting, links to where you found the info about a limit of 10.

I fought a similar battle yesterday and after an hour of mental gymnastics, I found the solution.

In my case, I discovered Event 1053 in the Application Logs on my Exchange box.
Resolution was two part

To work around this issue, assign the Exchange Servers group the right to change permissions against msExchActiveSyncDevices objects. To do this, follow these steps:

Start Active Directory Users and Computers.

Click View, and then click to enable Advanced Features.

Right-click the object where you want to change the Exchange Server permissions, and then click Properties.

Note You can change permissions against a user, an organizational unit, or a domain.
4. On the Security tab, click Advanced.
5. Click Add, type Exchange Servers, and then click OK.
6. In the Apply to box, click Descendant msExchActiveSyncDevices objects.
7. Under Permissions, click to enable Modify Permissions.
8. Click OK three times.

Are you trying to setup a new ActiveSync device?
If so, please check the following in your active directory:

Open the Active Directory Users and Computers and go to “View” and select “Advanced Features”

After that, find the user who is not able to use the ActiveSync, and double-click him, and go to “Security” tab then click “Advanced”…

Then just check the ckeck-box “Include inheritable permissions from this object’s parent” and click OK to close all the other windows…

After this, the user should be able to connect to the server using ActuveSync with no problems…

Check your event log with Powershell:

Get-EventLog -LogName 'Application' -Newest 1 -EntryType 'Error' -Source 'MSExchange ActiveSync' | Select EventID,EntryType,TimeGenerated,Category,Message | FL
