Microsoft’s documentation does not confirm that every current Outlook client has a command literally named “Forms Manager,” so the steps below apply to classic Outlook and should not be assumed to work unchanged in new Outlook, Outlook on the web, or Outlook for Mac.
What “Forms Manager” means in Outlook
Outlook custom forms are reusable layouts for items such as messages, posts, contacts, tasks, and journal entries. In the documented classic interface, there is not a universally verified command called Forms Manager. Instead, management is handled through the Developer tab, the folder’s Actions menu, and the Choose Form dialog.
The Microsoft Learn guidance on publishing locations applies to Outlook for Microsoft 365, Outlook 2021, Outlook 2019, and Outlook 2016. Other clients may expose different commands or omit classic custom-form features.
Create a custom form in classic Outlook
1. Start with a standard Outlook form
Custom forms must be based on a standard form. Choose the standard mail-message form for an email distributed to recipients, or the standard post form for an item posted in a public folder. Other standard forms support scenarios such as contacts, tasks, and journal entries.

2. Open the form designer
- Enable the Developer tab if it is not visible.
- Select Developer > Custom Forms > Design a Form.
- Choose the standard form that matches the item you are creating.
- Add fields, controls, additional pages, and any supported code, then set the form’s attributes.
3. Decide where the form belongs
Publishing location determines who can use the form and how they open it. Select a folder when the form belongs to one folder, Personal Forms Library for your own use, or Organizational Forms Library for centrally managed organization-wide use.
Where should you publish the form?
| Location | Best fit | Access and limitations |
|---|---|---|
| Folder Forms Library | A form used mainly with one folder, including common Contact, Post, Task, and Journal scenarios. | The form is available with that folder and appears on its Actions menu. A public-folder form is available to people who have access to that folder. |
| Personal Forms Library | A form used by one person. | Stored as a hidden item in the root of the default mailbox or PST. Open it through Choose Form. |
| Organizational Forms Library | A form reused across folders or shared throughout an organization. | Stored on an Exchange Server-based computer. An administrator must grant access and publishing permission. Open it through Choose Form. |
Microsoft’s selection factors include whether the solution is folder-based or message-based, how many people need it, how often it changes, offline availability, whether recipients are inside or outside the organization, and how users will open it.
Publish and open a form
Publish to a folder
- In the form designer, choose the folder as the publishing location and publish the form.
- Open that folder in Outlook.
- Use the folder’s Actions menu to select the published form.
This approach ties the form to that folder. It is useful when the folder itself defines the workflow, but it is less convenient when the same form must be reused in several folders.
Publish to Personal or Organizational Forms Library
- Publish the form to the appropriate library.
- In classic Outlook, expose Choose Form on the Developer tab if necessary.
- Select Developer > Choose Form.
- Choose Personal Forms Library or Organizational Forms Library, select the form, and open it.
Forms stored in either library are designed to be accessed through the Choose Form dialog. Organizational publishing requires the relevant Exchange configuration and administrator permissions; a user cannot bypass those requirements from Outlook alone.

Update an existing custom form
- Go to Developer > Choose Form and select the customized form.
- Open it in design mode and make the required changes.
- Select Developer > Publish > Publish Form to republish the updated form.
This documented republishing route applies to forms customized with form pages. Form regions cannot be published to the server through this method; Microsoft says they must be deployed through an add-in.
Storage, templates, and version pitfalls
When a form is published in a forms library, Outlook typically stores one copy and items refer to it through a Message Class field. Microsoft says this can reduce resource and bandwidth use compared with storing a separate form in every item.
You can save a form as an Outlook Template (.oft) for sending or backup. Treating a file-system copy or a folder item as the normal deployment method is risky: those copies become one-off forms and can lead to accidental deletion, version clutter, and unwanted side effects. If a centrally published form is also published to a folder for easier access, redeploy updates to both locations to reduce Outlook forms-cache problems.
Choosing the right management approach
- One folder, one workflow: use the Folder Forms Library and open the form from that folder’s Actions menu.
- One person: use the Personal Forms Library and Choose Form.
- Several folders or many users: use the Organizational Forms Library when Exchange and administrator permissions are available.
- Recipients outside the organization: check how the form will be delivered and whether the recipient’s Outlook environment supports the custom form.
- Frequent changes: prefer a centrally maintained library and republish updates rather than distributing many independent copies.
- Form regions: plan add-in deployment instead of relying on the form-page publishing route.
If you cannot find “Forms Manager”
First verify that you are using classic Outlook and that the Developer tab is enabled. Look for Custom Forms, Design a Form, and Choose Form rather than relying on a command named Forms Manager. If you are using new Outlook, Outlook on the web, or Outlook for Mac, the classic commands may not be present; the documented workflow does not establish cross-client support.
