Managing Shared Mailbox Signatures and Sent Items in a Departmental Setup (Outlook Classic)

Question

Hi all,

We have the following setup and requirements:

• Each user has their own individual work email account.
• Certain departments share a common email (e.g., ******@company.com) that is accessed by all members of that department.
• When replying to emails from the shared departmental email, we need the sent emails to be stored in the shared email's Sent Items folder, so all members can see the replies.
• We do not want emails to be sent "on behalf of"; the recipient should see the email as coming directly from the department email address.
• We understand that a shared mailbox doesn’t support a default signature for everyone, but we need a way for each user to use their own signatures when sending from the shared mailbox.

Additional Context:

• We are currently using Outlook Classic due to compatibility requirements with our internal MS Access applications while sending emails. Until we can fully migrate to web apps, we need to continue using Outlook Classic.

Issues we've encountered:

• We’ve had problems in the past where signatures for two users in the shared mailbox synced and one overwrote the other in the default signature, while the rest of the department did not experience this issue. It seems some users successfully set up their signature settings locally, which prevented syncing issues.
• Emails sent from the shared email are going into the personal Sent Items folder of the user. We've only granted "Send As" permissions in the past, but we're now experimenting with a shared mailbox setup where replies are copied to the shared mailbox's Sent Items folder. This seems to work, but we're still concerned about the signature issue.

Our questions:

1. Is there a reliable way to ensure that each user can use their own individual signatures when sending emails from a shared mailbox, particularly in Outlook Classic?
2. What is the best practice for managing shared mailboxes in Outlook Classic so that sent emails go to the shared mailbox's Sent Items and not the personal Sent Items, while also allowing for individual signatures?
3. We’re open to allowing users to log into their own and the department accounts separately, as long as signatures and sending behavior function correctly. Currently, the departmental account appears automatically when it detects "Send As" permissions—should we change this approach?

Thanks for any advice or solutions you can provide!

Hello Joel Cheah,

Thank you for your follow-up question. The approach you’re considering—keeping the departmental mailbox as a regular user mailbox and providing credentials to all users who need access—can indeed address some of the challenges you’re facing with sent items and signatures.

1. Sent Items:

• Automatic Storage in the Departmental Mailbox’s Sent Items:
  • When users sign in directly to the departmental mailbox as a second account in Outlook Classic, any emails they send from that account will naturally be saved in that mailbox’s Sent Items folder. This happens because Outlook treats it as a separate account, and all sent emails are stored according to the mailbox from which they were sent.
  • This approach would eliminate the need for any rules or additional configuration to move sent items, ensuring that all departmental emails are centralized in one place.

2. Signatures:

• Using the Correct Signature:
  • Since users would be signed in directly to the departmental account, they can set up a specific signature for that account within Outlook Classic.
  • Steps:
    • Users can go to File > Options > Mail > Signatures to create a unique signature for the departmental account.
    • Outlook allows users to set different default signatures for each account they have added, so they could use their personal signature for their personal account and the departmental signature for the departmental account.
• This means that the correct signature would automatically be applied when sending emails from the departmental mailbox, without the need for manual selection or third-party tools.

Considerations:

• Access Management:

Sharing the credentials of a regular user mailbox among multiple users requires careful management of those credentials to ensure security and compliance. It’s important to keep track of who has access and to periodically change the password if necessary.

Sharing credentials for a user mailbox may pose security risks, as all users with access can see each other's emails and make changes to the account settings.

• Maintenance: Managing a shared user mailbox can be more complicated than a shared mailbox, especially if users make changes to the account settings or delete emails accidentally.

Mailbox Limits:

• Regular user mailboxes may have different storage limits compared to shared mailboxes, depending on your organization’s licensing and settings. Ensure that the mailbox has sufficient storage, especially if it’s heavily used by multiple users.

Conclusion:

If you're willing to accept these potential drawbacks, using a regular user mailbox with shared credentials can be a viable alternative to address your concerns about sent items and signatures. Just ensure that users understand the importance of handling the shared account with care.

This approach can be a viable alternative to using a shared mailbox, especially for resolving issues related to sent items and signatures. It leverages the built-in functionality of Outlook Classic to keep sent items and signatures correctly managed without the need for additional tools.

If you decide to move forward with this setup and need further guidance, feel free to ask!

Appreciate your kind understanding. Have a great day!

Hello Eleni,

I have a follow-up question: Instead of converting the mailbox to a shared mailbox, what if we keep it as a regular user mailbox and provide the credentials to all users who need access? This way, each user would sign in to two accounts within Outlook Classic—their personal account and the departmental account.

Would this approach help in solving the issues we're facing with the location of sent items and the use of appropriate signatures? Specifically:

1. Sent Items: Would emails sent from the departmental mailbox be saved in that mailbox’s Sent Items folder automatically?
2. Signatures: Since users would be signed in directly to the departmental account, would they be able to use the correct signature for emails sent from that account without needing third-party tools?

I look forward to your advice on whether this approach might be a viable alternative.

Hello Joel Cheah,

Good day! Thank you for reaching out to the Microsoft Community.

Thank you for reaching out with your detailed query about managing shared mailboxes and signatures in Outlook Classic. I understand the complexities involved in ensuring proper handling of sent items and signatures in a departmental setup, and I'm happy to assist.

You’re facing a couple of key issues with shared mailboxes in Outlook Classic:

1. Signatures: Users need to use their own individual signatures when sending emails from the shared departmental mailbox.
2. Sent Items Location: Emails sent from the shared mailbox should appear in the shared mailbox's Sent Items folder, rather than each user's personal Sent Items folder.

Given that you're using Outlook Classic due to compatibility with internal Microsoft Access applications, I recognize the need for a solution that fits within this environment while addressing the specific challenges you're encountering.

Outlook Classic does not support setting different signatures for shared mailboxes directly.

However, here is a workaround you can use:

When sending an email from a shared mailbox in Outlook, the signature that appears is typically the one associated with the individual user, not the shared mailbox. This can indeed cause issues when a unified or specific signature is required for emails sent from the shared mailbox.

Using a Third-Party Tool (e.g., CodeTwo):Company-wide email signature management for your business (codetwo.com)

One effective solution is to use a third-party tool like CodeTwo. These tools are designed to manage and apply email signatures at the server level rather than relying on Outlook’s local signature settings. Here’s how using such a tool can address the issue:

Centralized Signature Management:

• CodeTwo and similar tools allow you to create and manage signatures centrally. This means that regardless of which user is sending the email from the shared mailbox, the appropriate signature can be automatically applied based on predefined rules.

Signature Syncing:

• The tool syncs the signature at the server level, ensuring that the correct signature is applied for the shared mailbox when emails are sent. This avoids the problem of users' individual signatures being used by default.

Customization and Flexibility:

• You can configure different signatures for different scenarios, such as when sending as a shared mailbox or as an individual user. This level of customization ensures that each email is branded correctly, regardless of the sender.

Steps to Implement This:

• Set Up CodeTwo (or Similar Tool):
  • Install and configure CodeTwo according to your organization’s requirements.
  • Define rules for when and how signatures should be applied, particularly for emails sent from shared mailboxes.
• Disable Local Outlook Signatures:
  • Since CodeTwo will handle the signature insertion, you can disable or remove local signature settings in Outlook to prevent conflicts.
• Testing:
  • Ensure that the setup works as expected by sending test emails from the shared mailbox and verifying that the correct signature is applied.

You can explore and get more information about CodeTwo's solutions for managing email signatures, disclaimers, and other features on their official website.Company-wide email signature management for your business (codetwo.com)

By using a third-party tool like CodeTwo, you can bypass the limitations of Outlook's local signature settings and ensure consistent, professional signatures across all emails sent from your shared mailbox. This solution is particularly useful in environments with strict branding requirements.

Another Option: Since Outlook Classic does not support automatic signature syncing for shared mailboxes, each user must manually configure their signature for the shared mailbox

• Open Outlook Classic.
• Go to File > Options > Mail > Signatures.
• In the Signatures and Stationery window, click New to create a new signature.
• Name the signature appropriately (e.g., "Department Shared Mailbox").
• Craft the signature using the available formatting tools.
• In the Choose default signature section, select the shared mailbox from the dropdown menu and specify if the signature should appear in new messages, replies, and forwards.

Create Custom Templates: Each user can create email templates with their individual signatures. When sending emails from the shared mailbox, users can use these templates to ensure their signatures are included.

• Steps to Create and Use Templates:
  1. Open Outlook Classic and compose a new email.
  2. Add your signature and any other content you want to include.
  3. Save the email as a template by clicking File > Save As, then choose Outlook Template (*.oft) as the file type.
  4. When composing an email from the shared mailbox, use this template to maintain the desired signature.

Save Replies in Shared Mailbox

If you aren;t an Admin, please contact your Admin or IT personal.

By default, the emails sent via a shared mailbox or reply to a message received in the shared mailbox are saved in the user's Sent Items folder. One of the best practices is to keep a copy of messages or emails sent via shared mailbox within share mailbox. To do this, follow these steps:

• Login to Microsoft or Office 365 admin portal and click Teams & groups > Shared mailboxes.

Then click on your Shared mailbox.

• Click on the Edit button below Sent items.

Enable the Copy items sent as this mailbox and Copy items sent on behalf of this mailbox options and click 'Save.'

Once enabled, emails sent by any user on behalf of the shared mailbox are also saved within the mailbox. This will help others check if the messages are sent and queries are resolved, preventing duplicate responses or messages.

Additionally, you can refer to this article;Open and use a shared mailbox in Outlook - Microsoft Support

Consider exploring upgrades or alternative solutions if feasible, as newer versions or web applications might offer more robust features for handling shared mailboxes and signatures.
