Microsoft Exchange synchronization.


synchronize public folders with your mailbox Cross-Domain Cross-Forest

Synchronization of any Exchange folder with one or many mailboxes makes it easy to synchronize for example public folders with your smartphone like iPhone or Android.

This service enables you to synchronize calendars, contacts, tasks, emails and other default elements of the Exchange server.

ExMixedFolders is a system service for Exchange Server which can synchronize folders within the Exchange server structure or it can synchronize folders, folder hierarchy or mailboxes with a second Exchange server. The service can be installed remotely, for example to access the Exchange online server or it can be installed directly on the Exchange server. The user whose Outlook folder is synchronized has no contact with the service, as it can be configured by an administrator. However, it is also conceivable to use the service without the help of the IT expert, since this can be set up via Autodiscover similar to the configuration of an account in Outlook. If you only need access to one mailbox, the license is free.

ExMixedFolders can be used by anyone who has access to the Exchange web service of their Exchange server. You can establish the connection to the server either with your own access data or by impersonation, on behalf of others.

1. Public folder synchronization with mailbox folders

Exchange public folder sync

Synchronization of public folders with local mailbox folders enables the user to synchronize public folders with smartphones, because Exchange Active Sync (EAS) can't sync it directly to the phone.

You can share a public contact-folder with all your team-members and change it for example.

In case you want to sync one or more public folder(s) with one mailbox, there is already a free license for it inside.

2. Exchange synchronization across different servers

Sync Exchange folders across different servers Cross-Domain Cross-Forest

Synchronization of folders between two Exchange servers, for example synchronization of public folders between two companies with different domains. You can sync mailboxes between domains as well for example if somebody works for different companies. Also migration between domains is imaginable.

3. Synchronization of Office 365 or other Exchange Online server contents

synchronize Exchange with Office365

You can use this program in order to sync Microsoft 365 or any other Exchange Online Providers (which activates EWS) between each others. You can synchronize content from one mailbox to another or from public folders to a mailbox.

As well you can use it to migrate between local Exchange and Exchange online, while the sync is running you can work on both systems.

It would, for example, be possible to offer your clients the service from your own cloud in the form of a subscription service. Also there are sceneries imaginable where you migrate mailboxes from and to Exchange Online.

4. Global Address List or ActiveDirectpry contactsynchronization

GAL Sync / ActiveDirectory Contactsync

In your phone which supports ActiveSync you have the possibility to search trough your Global Addresslist, but there is no built in function which shows you the profile if a number of those lists is calling. With ExMixedFolders you can sync these lists into your own mailbox contacts, which enables you this functionality

In order to provide your users the ActiveDirectory contacts you are now able to create synctasks which can sync GAL, ActiveDirectory or Office 365 contacts into the mailboxes. You can select the address-lists from AD or you can filter the addresses by your own filters.

5. Backup and recover Exchange folders

Backup and recover Exchange folders

Since Exchange 2010, you can also use ExMixedFolders to back up any Exchangefolder or folder structure. If necessary, you can restore them in an empty folder.

6. Import from other data sources

CSV Excel import to Exchange folders


If you need to import data from other databases by CSV or from an Excelfile, the import-task from ExMixedFolders is the right one for it. You can point to a file which contains the contacts, appointments or tasks and every time this file is changing, the import to Exchange will start again to update the selected Exchange folder.


With the ODBC Database Import task, you can specify a database as a source and a query to access the data you need.

iCal files into Exchange Calendar

With the Import-task "CSV, iCal, Excel ...." it's possible to import iCalendar files into an Exchange calendarfolder. The task runs in an interval which you can set. With this task you can import Google-calendars or for example holiday-calendars.

Additional job types (currently in beta status)


The software allows you to create multiple Exchange connections, so that the service has access to different Exchange servers, or mailboxes.

In order to build a connection between folders or even mailboxes you can build one or more service-connections. After you have successfully connected to your server, you can create synchronisationtasks which are dependent from the serviceconnections.



The software enables you to set up several Exchange connections. Thus, the service can access different Exchange servers or mailboxes.

Build folder pairs

Set up synchronization jobs, which create folder pairs. The folder pairs can be connected uni- or bidirectionally. A filter enables you to only synchronize elements of a certain category.

Synchronization method

Choose the synchronization method that suits you best:

  • Unidirectional

    With the right arrow, all new and changed elements are transferred to the folder configured on the right; deleted elements are also deleted there. When additional elements are created on the right side, these are not taken into account. The left arrow has the same function, only in the opposite direction.

  • Bidirectional

    The double-arrow synchronizes both folders in such a way that changes are taken into account and processed on both sides.

  • Mirroring

    The red arrow has a similar effect to the green arrow, with the difference that the elements created, changed or deleted to the right are undone. Newly created elements on the right side are deleted.

Minimum system requirements:

Exchange Server 2007 SP1 / 2010 / 2013 / 2016 / 2019 / Office365 and

OS: Windows Server 2008 R2 SP1, Server 2012, Server 2012 R2, Server 2016, Server  2019, Windows 7, Windows 8.1, Windows 10, Windows 11.
