Top 10 ActiveSync errors and troubleshooting information

Microsoft Windows Mobile version 5.0 support codeWindows Mobile 2003 support code (if different)Error messageTroubleshooting information
0x850200030x8004225EThe server could not be reached. This can be caused by temporary network conditions.The connection to Microsoft Exchange Server was lost. Typically, this condition is temporary. Try to synchronize again later.
0x80072efdThe server could not be reached. This can be caused by temporary network conditions.Typically, this condition is temporary. Try to synchronize again later.
0x8502000f
0x850100140x80042235ActiveSync encountered a problem on the server.A synchronization source, either Exchange Server or Microsoft Office Outlook, reported an internal error. Typically, this condition is temporary. Try to synchronize again later. However, if the condition persists, you may have to contact an administrator.
0x80072ee4The server could not be reached. This can be caused by temporary network conditions.Exchange Server reports an internal error. Typically, this condition is temporary. Try to synchronize again later.
0x850200020x800422BDThe server could not be reached. This can be caused by temporary network conditions.The connection to Exchange Server was lost. Typically, this condition is temporary. Try to synchronize again later.
0x8500200cSynchronization timed out waiting for user input (usually credentials)Try to resynchronize and look for information that the device-side synchronization is requesting, such as the user ID and the password.
0x85010005The server that ActiveSync queried returned a 404 error. Usually, this means that the server is not a valid Exchange front-end (which is usually due to the user entering the wrong server address).Confirm that the server address and other Exchange Server information is correct.
0x8502000eThe device attempted to synchronize when the phone was off.Confirm that the telephone is not in flight mode and that the network signal is strong enough.
0x86000209There was a synchronization error, and the device will now resynchronize all of the data to recover.

ActiveSync error code and troubleshooting information

Windows Mobile version 5.0 support codeWindows Mobile 2003 support code (if different)Error messageTroubleshooting information
0x85002000Not available.ActiveSync ran out of storage. Try to synchronize again after you free more memory.
0x850020020x80042001There is not enough free memory on your device to synchronize information. Delete unused files from your device or close programs that are running to free up memory.ActiveSync ran out of storage. Try to synchronize again after you free more storage.
0x850020030x80042002The server could not be reached. This can be caused by temporary network conditions.Synchronization was not completed because the device had to wait too long to establish a connection with Exchange Server. Try to synchronize again later.
0x85002004You have stopped synchronization.This is an informative message and does not indicate an error. Synchronization was manually stopped.
0x850020070x80042006ActiveSync encountered a problem on the server.A temporary problem exists with the server. Try again later. If the problem persists, you may have to contact an administrator.
0x85002008ActiveSync encountered a problem with the following item:This is an error synchronizing a single item. This error is also known as a "per-item" error. You usually can only correct this error by removing the item that caused the error. If you decide to synchronize the device again to determine whether the error persists, items that cause this kind of error will be skipped and will not appear again.
[Item Type]: [Item Name]
If the error persists, you may need to delete the item.
0x85002009Not available.A previous synchronization error requires that synchronized data be removed. However, that removal cannot be completed. Try to synchronize again. The removal should complete correctly.
0x8500200A0x80042009Your account information could not be detected. Choose Configure Server on the ActiveSync menu to check your Exchange Server credentials.When synchronization was set up with Exchange Server, the credentials page was left blank. Correct the credentials, or set up the device to only synchronize with a desktop computer. Then, try to synchronize again.
0x8500200B0x800421D9The server could not be reached. This can be caused by temporary network conditions.This message is frequently returned when Exchange Server is overloaded. Try to synchronize again later.
0x8500200D0x8004200CThe device timed out waiting for you to supply credentials.The Exchange Server credentials page was left open too long. Re-enter the Exchange Server credentials, and then try to synchronize again.
0x8500200FYou have canceled synchronization.This error usually occurs when you cancel the Exchange Server credentials page. Make sure that you are set up correctly to synchronize with the desktop computer or with Exchange Server. Then, try to synchronize again.
0x85010000Not available.This error code could be one of several minor Internet errors. Try to synchronize again later.
0x850100020x800421D2Access was denied. Choose Configure Server on the ActiveSync menu to check your server username and password.If you synchronize on a schedule, the synchronization has been changed to manual. After you reestablish access to Exchange Server, you can set up the synchronization schedule.
0x850100080x800421D8The proxy server you have specified is incompatible with your device. Specify the correct proxy server in your connection configuration.If you synchronize on a schedule, the synchronization has been changed to manual. After you successfully synchronize with Exchange Server, you can set up the synchronization schedule.
0x850100090x800421D9The server could not be reached. This can be caused by temporary network conditions.Because of poor network conditions, synchronization with Exchange Server could not be completed. Typically, this condition is temporary. Try to synchronize again later.
0x850100140x80042235ActiveSync encountered a problem on the server.A synchronization source, either Exchange Server or Outlook, reported an internal error. Typically, this condition is temporary. This condition has three known causes:

1) The initial synchronization with the device occurred when Outlook was offline. To work offline, Outlook must be configured for Cache mode. To quickly determine whether this is true, verify that the Work Offline command is on the File menu.

2) Outlook is not your primary e-mail client.

3) Antivirus programs are causing script blocking. Script blocking against Outlook prevents ActiveSync from accessing the Object Model in Outlook by intercepting all the ActiveSync calls to Outlook. If a user turns off the script-blocking feature in the antivirus program, users should be able toto synchronize successfully. This resolution only applies to users who perform desktop synchronization.

Installing ActiveSync 4.1 should resolve this error.
0x850100150x80042236ActiveSync encountered network problems or an internal server error while synchronizing.This kind of error is frequently returned when Exchange Server runs out of memory. Typically, this condition is temporary. Try to synchronize again later.
0x850100160x80042237ActiveSync encountered network problems or an internal server error while synchronizing.The network returned an error message. Typically, this condition is temporary. Try to synchronize again later.
0x850100170x80042238ActiveSync encountered a problem on the server.The desktop returns a "503 (too busy)" error whenever a pending request is already in the system. This behavior occurs because the desktop only accepts one request at a time. In this case, the device request takes too long to process or more than two minutes. The device sends another request, and the request causes the 503 error. To work around this problem, use one of the following methods:

Let synchronization fail the first time. Do not restart the computer, reconnect the device, and then give the synchronization process time to finish.

Or, the customer may have an item that causes ActiveSync to spend lots of time trying to synchronize. In this scenario, the customer must determine what item is causing the problem.
