Known Incompatibilities and Known Issues

Updated: (7.30.2018)

Even the best of technologies can at times be troublesome.
Known Issues:  http://support.diditbetter.com/kb/a2e_168.aspx

Note:  The above error is not directly related to a sync stopping issue, but only to opening up the Console. 
TIP: If Add2Exchange is stopping, and you have Outlook installed on the replication server to sync to Exchange 2013, 2016 or Office 365, it is most likely you are logging off as the service account,  so don’t.  It still runs as a service, but recent MS updates made the system unable to log off.  Keep the service account logged in and lock the machine with that user on and you should be fine.  If rebooting though, have to log in and stop and start the Service and then lock as that user.

The following is a historical listing of otherissues and other relevant information.

There are a few known incompatibilities we have found.  We are working hard to fix these, but in the interim these links should prove helpful:

Migration Wiz and Skykick Issues when migrating to O365

- 3/17/2017 update - Applicable for any folder type and for many to one or full mesh Contacts Relationship sync.  Some New features will match existing Contact items stripped of named properties.  However, this is only possible for one to one relationships.  Submit a support request for us to do a "preflight" for your ideal Migration plan!

https://www.migrationwiz.com/ 
3/15/16 Named properties and custom fields are not migrated with Migration Wiz or Skykick migration tools- It is critical to upgrade to Add2Exchange Enterprise and sync once prior to using this tool to migrate to Office 365 or hosted Exchange.  Our recommended option is to  dereplicate prior to the use of the tool for migration.  If dereplication is not done prior, the A2O Toolkit is required to remove Add2Exchange Copies in the destination folders.  It has been updated to accommodate the fact that Migration Wiz or Skykick does not sync named properties, the keys we use to determine our copies from originals. Use this link for further information. 

We were told this mailbox migration utility service WILL have functionality for an inplace migration of named properties, at the end of April 2013, yet does not have it as of March 2018. Be very careful when using these tools.

Presently, they are not compatible because they do not copy over the "named properties" of the copied items, so we completely lose control of them.  A local to hosted migration with this tool is not possible without dereplicating Calendars, Notes, Tasks,  Notes and depending on your configuration, Contact relationships. 
Export the setup in the Add2Exchange Console (Help Export Setup) and save it offline to make note of the current relationships, dereplicate prior and then install and license Add2Exchange Enterprise O365,  and set them up again using this new sync technology after the migration.   If Add2Exchange is installed on a Hub or Exchange Server, you will need to move it off to a virgin machine.   If you have migrated using this technology or premigrated and did not dereplicate prior, please contact technical support for the migration assistance immediately before you finalize the migration. 

With a proper onboarding process to O365, it is possible to dereplicate the appropriate relationships and keep some if not all Contact data in place, thereby not losing the Outlook type ahead of those users.   Please schedule a preflight BEFORE migration or presync of related folders.

Google sync

If you are using Google sync, and have bidirectional relationships, this second sync could cause items to revert back to original date or edit.  It is best practices not to have this service turned off.

Changed Items are Reverting Back

It could be that the relationships are not set to copy changes back, so make the relationships to sync back to the source and always overwrite the source with those changes,

It may also be cause by a third party product updating the items.  Please refer to the links provided below as they may help to solve this problem.
