The Mobile Worker

Add2Exchange is used by mobile workers who need their company contacts and work calendars accessible for viewing on smartphones and tablets when away from the office. Add2Exchange synchronizes and copies appointments and contacts from the selected Microsoft Exchange public folders (or the GAL) to your local mailbox folders where it needs to be for mobile device access. You can also easily sync new items made or edited on your mobile back to Exchange public folders (and even to other users).

Key Features

Group relationship lists and templates help you automatically create relationships based on distribution lists. One of the more popular features of Add2Exchange is the built in Relationship Group Manager which entirely eliminates creating individual relationships one at a time. Somewhere between creating your 20th and 100th relationship, we figured you would prefer a quicker, better way to do this with less fuss and this is it! With the Relationship Group Manager, you can use Exchange distribution groups and create relationship templates, attach to the group to make and remove relationships automatically based on the inclusion or exclusion in the list. Creating new relationships is done by adding users to the distribution group. The next time Add2Exchange syncs, it creates each relationship and can even create new folders for you, if necessary. Group relationships save you time by helping you manage large number of relationships on an on-going basis with relationship templates and distribution lists rather than creating each sync relationship pair, one at a time.

Global address list sync. Use the Add2Exchange GAL Sync Manager to automatically replicate your global address list to selected users’ local mailbox contacts for viewing on smartphones. To initialize GAL synchronization, the contacts from your active directory will populate into a ‘GAL Cache’ folder (ex. a public folder or other Outlook folder such as private mailbox or resource folder dedicated for caching the GAL contents). Once the GAL synchronization is initialized, you’ll set up your sync relationships from the source folder (GAL Cache folder) to the destination folders for each of the users you want to share and replicate it to. The GAL contacts will automatically sync down to each of the selected users’ personal folders and from there the device’s sync software takes over for viewing on the phone.

Central management with built in console. Easily add and remove users from the sync mix, or modify replication settings with just a few clicks.


Integrated folder cloning. Make individual folders automatically for any new relationships. Folder cloning creates a mirror image of the folder structure from a template account to multiple destination mailboxes. This is useful when creating a new folder structure for sync purposes when you want a separate, non-default folder to receive the contents of synchronization from a source folder, but you do not have the desired folder structure made in the destinations yet.

Custom form support. Works with your Outlook custom forms when published to both locations.


Relationship Attributes. Once installed, configure the folder relationship with the type of replication needed for additions, modifications, and deletions. For example, if the source item is deleted, the destination item can be deleted or marked as deleted, or set to do nothing at all. If users make changes to their own copy of the item, settings in the folder relationship within Add2Exchange can be set to untie the original copy to preserve the changes made in the private copy and then make a new tied copy from the source, overwrite the changed copy, or do nothing.

Date range control for past and future calendar recurrences. Specify how far into the past and future to sync recurring appointments. The “Sliding Date Range” feature for recurring appointments saves replication time by reducing the number of items to process when replicating items very far in the past. Add2Exchange copies all items within the date range specified from the source to destination folder(s), will copy recurring items, and handle exceptions to recurring items if the original recurring item is within the replication period.

Powerful add-on tools. Essential tools for your IT/Exchange administrator to better support your Add2Exchange installation —  the Recovery and Migration Manager (RMM) and the ToolKit. The Recovery and Migration Manager tool is useful for easily repairing of systems due to Exchange migrations or Add2Exchange migrations, troubleshooting alerted relationships, or fixing something as common as an active relationship in alert when, for example, someone gets married (or divorced) and changes their email address. The ToolKit offers a wide range of special functions such as the global forms replacement, advanced reset and ‘start over’ options, and higher level reporting and analytical tools.

  • Scalable and flexible. License one folder type (Calendars or Contacts) or the Sync Suite (Contacts, GAL Sync Manager, Calendars, Tasks, Posts, Notes). Our licensing is simple. We offer the following licensing tiers —  20, 50, and unlimited relationships. The unlimited relationship license covers one replication machine so you can create ‘relationships’ as needed when adding new users or folders to the sync mix. If Calendars and Contacts are required and synced at different intervals, discounted licenses are available for additional installations when purchased with the main license.  Smaller licenses are available – call for pricing.

What is a relationship? Every source to destination combination (folder pair) equals one relationship. The source is the folder the items are created in and the destination is the folder you want these items to sync to.
