Lotus Notes Calendars to ICS FAQs

1. Do I need to have IBM / HCL Lotus Notes installed on my PC to convert calendars to ICS?

Yes. Lotus Notes needs to be installed on the PC for NSF conversion, and the NSF file should not be encrypted.

2. Can I import the converted .ICS calendar file into Google Calendar and Apple iPhone/Mac Calendar?

Yes — Google Calendar, Yahoo calendars, Thunderbird, and MS Outlook all work with the ICS files, and you can open them in Gmail too. Apple Calendar / iPhone / Mac aren’t called out by name here; if those apps accept standard ICS, you can try importing there.

3. Does the software support recurring events, meeting reminders, and timezone specifications?

It exports appointments, meetings, events, alerts, and recurrence, and keeps calendar meta properties intact. Separate timezone-offset or reminder-alarm controls beyond alerts aren’t listed as their own options.

4. Can I export all Lotus Notes calendar events into a single consolidated master .ICS file?

You get one ICS file for every calendar in the NSF, and you can convert a single calendar or several in the same batch. There isn’t a separate “one master ICS for the whole NSF” mode beyond that.

5. Will the conversion process preserve attendee lists, meeting descriptions, and organizer details?

Complete calendar data and meta properties stay intact — appointments, meetings, events, alerts, and recurrence are covered. Attendee lists, organizer fields, and description labels aren’t called out as separate fields.

6. Which versions of IBM / HCL Lotus Notes (e.g., v14, 12, 11, 10, 9.x) are supported?

It works with all Lotus Notes versions. We don’t list separate badges for HCL Notes 14, 12, 11, 10, or 9.x.

7. Can I extract calendar entries from heavily sized or archived Lotus Notes NSF databases?

There’s no file-size limit for NSF to ICS conversion. The NSF must not be encrypted. Archived NSF isn’t listed as a separate mode beyond that.

8. What are the specific capabilities and export limitations of the free trial demo version?

The free demo exports up to 10 items so you can test the conversion. The full license removes the limit and starts from $29.
