365 Pro Toolkit Release Notes

2.0.5 (7/23/2026)

Create group page (Tools > Groups > Create group): build any group type from one screen, covering all four types (Microsoft 365, Security, Distribution list, Mail-enabled security).
Group email address with domain picker for mail-enabled group types.
Microsoft 365 style slide-out picker for choosing owners and members: search by name or UPN, check people from the list, and review your choices in the Selected panel.

Bulk update members runs in parallel: a 120 member run that took nearly two minutes now finishes in around 30 seconds, and it keeps scaling for larger jobs.
Remove selected on Groups > members is parallelized too, turning a multi minute job into seconds.
Group Members export drops straight in: the bulk importer matches columns by header name (Group, Member, Action) and ignores the rest.
Flexible member matching: members resolve by display name, user principal name, email address, or object ID.
Add or Remove toggle: if a bulk file has no Action column, pick the action once and it applies to the whole file. Semicolon separated members in one cell are still supported.

Remove multiple group members at once. The Members tab in Tools > Groups now has checkboxes and a “Remove selected” button, so you can remove several members in one action instead of one at a time.

Bulk update members is smarter about existing membership: adding a user who is already in a group (or removing one who isn’t) now counts as a success instead of an error, so re-running a file no longer reports false failures.
Failed rows in Bulk update members now show the actual reason from Exchange (and log the full detail), instead of a generic message.
Clicking Apply on Bulk update members now shows a spinner and updates each row as it completes, so it no longer looks frozen while it works.

Convert to shared mailbox: Convert a user mailbox to shared right from Tools > Mailboxes (and in bulk from Stale Accounts), with an option to remove the user’s license in the same step to free up the seat.
Stale Accounts, new views: Added Inactive Mailboxes and Stale OneDrive alongside the existing user views, so you can find unused mailboxes and OneDrive accounts by inactivity.
Stale Accounts, remove license: Select disabled or inactive accounts still holding a license and remove it in bulk to reclaim seats.

Stale Accounts now handles very large tenants efficiently, loading results a page at a time instead of pulling every account into memory.
Sync all in the Sync Manager runs sources in parallel again, so a full sync completes faster and shows progress instead of appearing to hang.

Disabling or deleting an account on the Stale Accounts page now updates its status immediately, without a page refresh.
The user count on report pages no longer drifts to the far right when a filter sits next to the search box.
Fresh installs could fail to start the database on servers missing the Microsoft Visual C++ runtime. The runtime is now included with the installer.

Updated the authorization page and moved the GCC checkbox below the “Authorize Now” button.

Fixed – Error input string was not in a correct format. This error would randomly popup. It has been fixed.
