It is possible to access a server using two or more Outlook clients at the same time. When an item (contact, event, etc.) is opened in the first client, and changed in the second one, you can select how the conflict will be resolved:

• Server wins: the data on the server are used.

• Client wins: the data changed in client are used.

If a folder contains the indicated or lower number of emails, the emails are synchronized. If the email quantity in folder exceeds the indicated number, Outlook Sync does not loop over all messages, it checks only the emails that are in a change report from Outlook. However, Outlook does not always reports about the changes, some emails may be missed. 100% functionality is guaranteed only if Outlook Sync checks all emails.

We do not recommend setting this value much higher than 1024 because the processing consumes a lot of CPU resources.

If an email size does not exceed the indicated number, the whole email is downloaded. If the email size exceeds this number, only email header is downloaded. The whole email is downloaded only if you click it. This field is enabled only when the Custom option (see lower) is selected.

Select one of the following:

• Custom: only emails that do not exceed the email size specified in Threshold for full download will be downloaded in full during synchronization.

• Headers: only email headers will be downloaded during synchronization.

• Full: all email content will be downloaded during synchronization.

Check to apply threshold to messages that are already in your mailbox.

Outlook Sync will synchronize only those items that were changed during N days after the last synchronization.

Specify a pause between processing of single items.

Check to skip Trash folder check when you start Outlook.

Specify the SMTP server port for outgoing messages.

Specify the POP3 server port for incoming messages.

Click buttons to start/stop the auxiliary POP3/SMTP server.
