Frequently Asked Question

Is there a way out to copy Lotus Notes email folder to another without using Lotus script?

Off course. You can copy one NSF to another using NSF merge Software.
Earlier I used createDocument to copy mail, where email formatting lost. So I used the Script where I get retained properties of mail. But new issue arises, it is taking too much time to copy mail from one nsf to another
Don't worry, the NSF Merge software is too fast to join & combine NSF Files. It just take 15 minutes to move 650 MB of NSF to another having 5000 emails.

Would I be able to move emails, contacts, calendar, notes & task from another NSF database ?

Yes, these all items you will get in your new NSF file
One more issue I have faced when I move my Lotus Notes database to another NSF, I found various duplicate email in another NSF
When you move your one NSF file to another using the SysTools NSF Merge software, it provide you the "Remove Duplicate". By checking this option you will get the new merged NSF file without having any duplicate items
Would I get the previous rule migrated too in my NEW NSF File ?
No, the software has nothing to do with the internal Lotus Notes settings. You need to add the rules manually

How do I combine my archived Lotus Notes .nsf files so that I am only left with 1 file?

You will have to combine the NSF files and achieve the desired output. However, being the end user, you have the complete freedom to choose between joining and merging NSF files.
What is the difference between these two options?
When you merge your NSF files, you get a common folder with the same name, for example: if both the NSF files have inbox folder then they will be listed in same Inbox folder.
OK, Single Inbox in a single NSF file?
Yes, exactly, both the Inbox folders will merged together & listed but within a Single INBOX of an individual source NSF file only. Great, now I got your point!

Can I merge my password protected NSF files?

No, the software does not support password protected NSF file for merging.
How to know which NSF files are password protected or not? I have a folder in which there are multiple NSF files & I am unaware about the ones that are and are not password protected. If I try to merge a set of password protected NSF files with unprotected NSF files, would I encounter any error message?
No, the NSF Merge Tool simply skips the password protected NSF files & merges the rest of the files.

My NSF file size increases tremendously after merging 100 NSF files. Is there a way to optimize its file size?

While merging NSF files, did all the files contain deleted items? How frequently do you empty your trash folder?
No, I haven't cleared my trash folder yet because I did not feel the need. However, after merging, I feel like removing them all at once.
Yes, you can do that. The software features an option to exclude deleted items. After doing that, you will notice that your NSF file has comparatively shrunk in size.
Thank you so much for adding this needful feature.

Is it possible to combine two address books of Lotus Notes together? I joined a new workplace where there are around 200 employees. They have this custom of introducing new employees to all the office members through mail. I do not want to type all the email IDs manually.

You can ask one of your colleagues for their address book (Names.nsf), which will be storing all the contacts.
Agreed, but I can't touch the names.nsf file without overwriting the other. In addition, I have my personal contacts too. I'll lose them if I overwrite the names.nsf.
Then in this case SysTools NSF Merge is the best option, because it merges two address book of Lotus Notes, without overwriting, & you won't have to lose any of your contacts in the process.

Will I be able to merge Domino database having the file extension .nsf with an existing .nsf file? Will I be able to access all the emails in Lotus Notes?

Yes, in offline mode you can copy the NSF file of Domino server to your target PC in order to merge two NSF Files together. For the software both files are NSF files so there will be no issue in merging these two files.
I am unable to find the contacts of Domino server in my NSF file?
Yes, because your contacts are stored separately in Domino Server as names.nsf. Browse Names.nsf files on the software and Lotus Notes contacts will be listed in a single Address book.
