Can EdbMails migrate Lotus Notes NSF files directly to Office 365?

Yes. EdbMails reads accessible offline NSF mailbox files and migrates supported Notes email and other mailbox items directly to a mapped Microsoft 365 destination without first exporting the source to PST. See the Lotus Notes migration guide .

What must I install before performing NSF to Microsoft 365 migration?

The EdbMails guide requires IBM Lotus Notes to be installed for source NSF access. You also need the EdbMails application, readable NSF files, internet connectivity and prepared Exchange Online destination mailboxes. Unlike NSF-to-PST export, this direct migration does not require an Outlook PST stage. Review the prerequisites .

How do I migrate NSF mailboxes to Microsoft 365 with EdbMails?

Open EdbMails, choose NSF Export and Migration, select NSF to Office 365 and add the source NSF files. Preview the available data, connect to the destination using its supported Microsoft Entra ID registration and consent workflow, map the target mailboxes, optionally filter the data and start the migration. Review logs and target content afterward. See the step-by-step instructions .

How should I prepare the target Microsoft 365 mailboxes?

Provision the required Exchange Online users and licenses, make sure mailbox access works, and identify which destination mailbox corresponds to each source NSF file. Check quotas and any archive requirements before migrating large Notes mailboxes. See the Microsoft 365 preparation steps .

Does NSF migration use OAuth 2.0 and Microsoft Entra ID?

EdbMails uses the documented Microsoft 365 destination registration and permissions workflow, including Auto Registration or Manual Registration where supported. Complete tenant consent with the appropriate administrative account and check that the destination mailboxes load successfully. See target Office 365 connection guidance .

Can I migrate multiple NSF files to different Office 365 users?

Yes. EdbMails supports adding multiple NSF files and mapping each source to the corresponding Microsoft 365 destination mailbox. Verify every assignment before migration, especially if users have changed names or email domains. Review source and destination mapping .

Can EdbMails migrate Lotus Notes contacts, calendars and tasks?

EdbMails documents migration of supported NSF mailbox data, including emails, contacts, calendars, tasks and attachments. The exact results depend on the data available and supported in each NSF. Custom Notes databases, forms or application workflows should not be assumed to convert into Microsoft 365 equivalents. See supported items .

Can I migrate only selected NSF folders or dates?

Yes. EdbMails lets you select relevant source items and apply supported filters such as date, sender or subject to limit the migration scope. Review the settings before starting and compare the target with the selected source preview. See the filtering options .

Can I repeat an NSF to Microsoft 365 migration incrementally?

Yes. EdbMails supports repeat incremental migration passes using maintained job state for eligible new or changed items. Use the same source-to-target mapping and make sure any newly added messages are actually present in the NSF files selected for the next run. Read incremental migration guidance .

What if a Notes NSF file is inaccessible or damaged?

Preserve a copy of the source and first verify that IBM Notes can access it with the correct user authorization. EdbMails can process supported, readable NSF data, but it cannot guarantee recovery of data that is absent, severely corrupted or protected by an unavailable credential. Preview the source before migration.

What is included in the EdbMails NSF migration free trial?

The trial allows you to scan and preview NSF mailbox content and test the workflow with the published limited item allowance for supported mailbox operations, normally 30 items per folder. Use the test to confirm destination mapping and sample content. Download the trial .

How do I verify migrated Lotus Notes data in Microsoft 365?

Check EdbMails migration logs, inspect selected destination mailboxes and compare representative emails, attachments, contacts, calendar items and folders with the source preview. If expected content is missing, review source availability, filters and mapping before another pass. See the guide .
