My company's O365 account has it, but my student (also 0365) and classic Outlook account doesn't. If you already have access to your company shared mailbox in Outlook, the steps are rather simple: Signatures and Stationery window, on the E-mail Signature tab, click. It's a new feature that is not available for everyone yet. For this, you need to add a shared mailbox to your Outlook as a second account. Therefore, you should consider creating an additional signature for the Outlook Web App.

So, how I can modify the already existing signature? Or, how I can create a new signature? Open Outlook on the web and click on the gear icon in the top right corner. But I can't find find any information about that. At the upper right on the Outlook browser interface, click Options > Settings > Mail Type in and format your signature in the E-mail signature. You need to copy your email signature with all styles. I can see that now, it's possible to manage multiples signatures in OWA.

Today, I was trying to update my signature with PowerShell but nothing happened, the signature in the browser is not changed at all.īut if I use Get-MailboxMessageConfiguration, the new signature is there:

On the Message menu, select Signature > Signatures. No permission problems, no configuration problems, nothing. Create your signature and choose when Outlook adds a signature to your messages Open a new email message. To add a specified signature to a message manually, select the ellipsis icon (.) at the top of the message and then insert signature. Here, you can select the signature you want. Until now, I was using Set-MailboxMessageConfiguration in PowerShell to change OWA's signatures and it worked perfectly. First, log into your Outlook account on a computer and go to Settings > Options > Email Signature.
