I have been an advocate of Lotus Organizer for many years and I was wondering if anyone knows if it's compatible with IBM Notes or even better with IBM Verse?
As far as I know, IBM Lotus Organizer has been discontinued some time ago, while both IBM Notes and Verse are still being developed, so getting them to work together may be an issue. However, my advice to you is to contact IBM directly by going to this URL: https://www.ibm.com/contact/us/en/?lnk=flg-cont-usen?lnk=flg and selecting the option that best describes your region and requirement. The company's tech support will give you all the compatibility information that you require.
