Is EasySync Pro supported if it is used with customized Lotus Notes mail templates?
No, synchronizing customized Notes mail templates with EasySync Pro is not supported.
If no significant changes are made to the Calendar, To Do, and Mail forms, EasySync Pro will generally still be able to sync with databases that use customized templates. However, it is difficult to anticipate how changes may affect synchronization. Therefore, IBM/Lotus does not support this.
As a general rule, deleting fields from forms or changing the manner in which data is stored in the documents will cause problems when synchronizing with EasySync Pro.
