If this is your first time using Add2Exchange or you are upgrading or migrating, post here.
Even the best of technologies can at times be troublesome.
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:

3/15/16 Items Not migrated with Migration Wiz - 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 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 2016.
At present it is not compatible because it DOES NOT copy over the named properties of the copied items, so we lose control of them. A local to hosted migration with this tool is not possible, Export the setup in the Add2Exchange Console (Help Export Setup) and save it offline to make note of the relationships, dereplicate prior and then crossgrade to Add2Outlook and set them up again using this new sync technology after the migration. If you have migrated using this technology and did not dereplicate prior, please contact technical support or license the Add2Outlook Toolkit for Migrationwiz migration assistance immediately so we can dereplicate the prior configuration before your users start using the migrated to technology.
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.
*update* iOS update 6.0.1 is now out and most of the bugs have been fixed. You can read about it here: http://updates.gizmodo.com/post/34769325331/ios-update-6-0-1-is-out-and-its-mostly-bug
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.
