IBM Lotus Notes/Domino Limits


Maintained as a general resource for IBM Lotus Notes/Domino developers and administrators, with information coming from Lotus Notes Help, IBM technotes, as well as developers and admins like you! If any limits seem wrong to you, or if you have experience that says the IBM documentation is wrong, let me know. Email me about additional limits we should include, or with general suggestions for how to make this resource better. For suggested changes to specific limits, or to note bugs or caveats, click on the symbol next to each entry.

This is not official documentation, although much of it is based on official documentation. It is what you can expect from IBM Lotus Notes/Domino by way of limitations, if you don't know better. If you do know better, we'd like to! Limits that are unverified are usually marked as such.

If this is helpful to you, please share this resource with others:
