A few special options cannot be set in TbSync directly and must be set in Thunderbird's advanced options. You can find them here:
Defines the maximum time to wait for an answer from the server, in milliseconds. If that timeout is reached sync stops with an timeout error.
Options for Exchange ActiveSync
Defines how many old events should be synced from the server to Thunderbird. The following integer values are allowed:
- 0 (all)
- 4 (2 weeks)
- 5 (1 month)
- 6 (3 month)
- 7 (6 month)
Defines the maximum items transmitted per request.
