Synchronization failure settings
There are options you can choose whenever a synchronization fails. E-mails that fail to synchronize can be moved to a specified folder. Or, you can enable the option to notify specific users via e-mail of the failed synchronization.
Send error messages to the users by e-mail: It is not recommended to use this option
without enabling Move unsuccessfully synchronized e-mails to the following subfolder as
well. Connector stores the last reason for a failure on the message level
(mmSyncStatus property) and would not send another error message unless
the error reason changes, but in a scenario where connector is not able to access the
mmSyncStatus property (e.g. if decoding of e-mail fails), it would keep
sending error messages over and over.
For further details, see Sending warning and error messages to users.
Move unsuccessfully synchronized e-mails to the following subfolder: If this option
is enabled, e-mails which could not be synchronized are moved to the specified subfolder of
the synchronization folder. For example, if you have defined
/<inbox>/crm as the synchronization folder and
Sync_Failure as the failure folder, the connector creates a folder
/<inbox>/crm/Sync_Failure and moves the e-mails into this folder.
The Connector no longer tries to synchronize these e-mails.
