ShareGate Migrate release notes

The release notes for the 10 most recent ShareGate Migrate releases

Updated today


ShareGate Migrate 26.4.4

17 April 2026

What's new

  • Resource mailboxes (room and equipment) are now supported with Copy mailboxes. Released via an online feature flag on April 20.

    • They appear with direct type-to-type mapping at the destination.

    • Emails, calendar events, booking policies, and calendar processing settings are copied.

    • Incremental migration is supported via the app and PowerShell.

What's fixed or improved

  • We fixed an issue where users without full SharePoint Admin permissions could not start their migrations, resulting in an unauthorized error.

  • We resolved a problem that caused PowerShell scripts using the Add-SiteCollectionAdministrator command to trigger browser re-authentication requests when running in a loop.

  • We’ve updated Azure Active Directory references to Entra ID in some error messages to align with Microsoft's current terminology.


ShareGate Migrate 26.4.3

14 April 2026

What's new

  • We've added a Rerun as incremental button to the Copy summary screen of any completed Copy mailboxes and Copy from Gmail migration task.

  • We've added a Last run date and Status column in the Copy mailboxes and Copy from Gmail source selection screen to provide visibility into which mailboxes were already included in a previous migration.

What's fixed or improved

  • When the app encounters specific connection or validation delays during sign-in, it will now automatically retry with increasing wait times, helping you stay connected in environments with intermittent network latency.


ShareGate Migrate 26.4.2

7 April 2026

What's fixed or improved


ShareGate Migrate 26.4.1

1 April 2026

What's fixed or improved

  • We've improved the handling of attachments with Copy mailboxes to mitigate hanging issues.


ShareGate Migrate 26.3.7

30 March 2026

What's fixed or improved

  • You can import CSV mapping files to replicate previous Copy identities operations.

  • You will get a proper error message when copying Mail rules with a Before or After condition, or a Pin to Top action with Copy mailboxes.

    • This update addresses a recent Microsoft change that affected how unsupported mail rules are handled during migration.

  • We removed a permission from the general ShareGate Migrate permission consent set for the new consent of the Entra Enterprise app.

    • This only affects the new consent of the app; the permission remains in the old version of the enterprise app for compatibility.


ShareGate Migrate 26.3.6

25 March 2026

What's new

  • Workspace admins with a ShareGate Enterprise subscription can select how activations are distributed across their workspace using new Seat allocation mode settings in ShareGate Home starting tomorrow. This release includes new activation messaging for this change.

What's fixed or improved

  • We fixed an issue that caused SharePoint connections using modern authentication to incorrectly prompt for consent again after it had already been granted.

  • We've improved the error messages you get when copying calendar attachments that are too large with Copy from Gmail and Copy mailboxes.


ShareGate Migrate 26.3.5

23 March 2026

What's new

  • Copy Entra ID users and groups with Copy identities (currently in beta for ShareGate Pro and Enterprise subscribers) to reduce manual setup and streamline your migration preparation.

  • You can now copy group calendars with Copy mailboxes.

What's fixed or improved

  • A proper message is displayed instead of a generic null reference error when trying to use Modern authentication to connect to an on-premises SharePoint environment, which is not supported.

  • We fixed an issue that would cause reports to fail with a user not found exception error when certain files reported on were checked out by users who have since been deleted.


ShareGate Migrate 26.3.4

13 March 2026

What's fixed or improved

  • We fixed an issue that would cause Google Calendar migrations to fail with the error, There’s no repository factory supporting the authentication type: Google at the start of the process when launching a Copy from Gmail migration.

  • We solved a problem that would cause files with the hash symbol (#) in their name to fail copying in Normal mode.


ShareGate Migrate 26.3.3

10 March 2026

What's fixed or improved

  • We solved an issue that prevented emails from being migrated when copying archive mailboxes with the error Failed to create mail message.


ShareGate Migrate 26.3.2

9 March 2026

What’s new

  • Modern authentication is now available to connect to your Microsoft 365 tenant across the app.

What's fixed or improved

  • When a source user is identified as external, and the same external user exists at the destination, they are automatically mapped together to ensure correct permission assignment when they are not mapped manually.

  • Fixed an error that could occur when forwarding external calendar events with Copy mailboxes, preventing ToRecipient cannot be empty errors during migration.
