Certificate renewal for Office 3. Azure AD users. Overview. For successful federation between Azure Active Directory (Azure AD) and Active Directory Federation Services (AD FS), the certificates used by AD FS to sign security tokens to Azure AD should match what is configured in Azure AD. Any mismatch can lead to broken trust. Azure AD ensures that this information is kept in sync when you deploy AD FS and Web Application Proxy (for extranet access). This article provides you additional information to manage your token signing certificates and keep them in sync with Azure AD, in the following cases: You are not deploying the Web Application Proxy, and therefore the federation metadata is not available in the extranet. You are not using the default configuration of AD FS for token signing certificates. You are using a third- party identity provider. Default configuration of AD FS for token signing certificates. The token signing and token decrypting certificates are usually self- signed certificates, and are good for one year. By default, AD FS includes an auto- renewal process called Auto. Certificate. Rollover. If you are using AD FS 2. Office 3. 65 and Azure AD automatically update your certificate before it expires. Renewal notification from the Office 3. Note. If you received an email or a portal notification asking you to renew your certificate for Office, see Managing changes to token signing certificates to check if you need to take any action. Microsoft is aware of a possible issue that can lead to notifications for certificate renewal being sent, even when no action is required. Azure AD attempts to monitor the federation metadata, and update the token signing certificates as indicated by this metadata. Azure AD checks if new certificates are available by polling the federation metadata. If it can successfully poll the federation metadata and retrieve the new certificates, no email notification or warning in the Office 3. If it cannot retrieve the new token signing certificates, either because the federation metadata is not reachable or automatic certificate rollover is not enabled, Azure AD issues an email notification and a warning in the Office 3. Check if the certificates need to be updated Step 1: Check the Auto. Certificate. Rollover state. On your AD FS server, open Power. Shell. Check that the Auto.
Certificate. Rollover value is set to True. Get- Adfsproperties. Note. If you are using AD FS 2. Add- Pssnapin Microsoft. Adfs. Powershell. Step 2: Confirm that AD FS and Azure AD are in sync. On your AD FS server, open the Azure AD Power. Shell prompt, and connect to Azure AD. Note. You can download Azure AD Power. Shell here. Connect- Msol. Service. Check the certificates configured in AD FS and Azure AD trust properties for the specified domain. Get- Msol. Federation. Property - Domain. Name < domain. The AD FS property Auto. Certificate. Rollover must be set to True. This indicates that AD FS will automatically generate new token signing and token decryption certificates, before the old ones expire. The AD FS federation metadata is publicly accessible. Check that your federation metadata is publicly accessible by navigating to the following URL from a computer on the public internet (off of the corporate network): https: //(your. For example, the following scenarios might work better for manual renewal: Token signing certificates are not self- signed certificates. The most common reason for this is that your organization manages AD FS certificates enrolled from an organizational certificate authority. Network security does not allow the federation metadata to be publicly available. In these scenarios, every time you update the token signing certificates, you must also update your Office 3. Power. Shell command, Update- Msol. Federated. Domain. Step 1: Ensure that AD FS has new token signing certificates. Non- default configuration. If you are using a non- default configuration of AD FS (where Auto. Certificate. Rollover is set to False), you are probably using custom certificates (not self- signed). For more information about how to renew the AD FS token signing certificates, see Guidance for customers not using AD FS self- signed certificates. Federation metadata is not publicly available. On the other hand, if Auto. Certificate. Rollover is set to True, but your federation metadata is not publicly accessible, first make sure that new token signing certificates have been generated by AD FS. Confirm you have new token signing certificates by taking the following steps: Verify that you are logged on to the primary AD FS server. Check the current signing certificates in AD FS by opening a Power. Shell command window, and running the following command: PS C: > Get- ADFSCertificate –Certificate. Type token- signing. Note. If you are using AD FS 2. Add- Pssnapin Microsoft. Adfs. Powershell first. Look at the command output at any certificates listed.

Latest bug fixes for Microsoft Windows, including fixes for some possible DoS attacks. If AD FS has generated a new certificate, you should see two certificates in the output: one for which the Is. Primary value is True and the Not. After date is within 5 days, and one for which Is. Primary is False and Not. Microsoft Office Certificates TemplatesAfter is about a year in the future. If you only see one certificate, and the Not. After date is within 5 days, you need to generate a new certificate. To generate a new certificate, execute the following command at a Power. Shell command prompt: PS C: \> Update- ADFSCertificate –Certificate. Type token- signing. Verify the update by running the following command again: PS C: > Get- ADFSCertificate –Certificate. Type token- signing. Two certificates should be listed now, one of which has a Not. After date of approximately one year in the future, and for which the Is. Primary value is False. Step 2: Update the new token signing certificates for the Office 3. Update Office 3. 65 with the new token signing certificates to be used for the trust, as follows. Open the Microsoft Azure Active Directory Module for Windows Power. Shell. Run $cred=Get- Credential. When this cmdlet prompts you for credentials, type your cloud service administrator account credentials. Run Connect- Msol. Service –Credential $cred. This cmdlet connects you to the cloud service. Creating a context that connects you to the cloud service is required before running any of the additional cmdlets installed by the tool. If you are running these commands on a computer that is not the AD FS primary federation server, run Set- MSOLAdfscontext - Computer , where is the internal FQDN name of the primary AD FS server. This cmdlet creates a context that connects you to AD FS. Run Update- MSOLFederated. Domain –Domain. Name . This cmdlet updates the settings from AD FS into the cloud service, and configures the trust relationship between the two. Note. If you need to support multiple top- level domains, such as contoso. Support. Multiple. Domain switch with any cmdlets. For more information, see Support for Multiple Top Level Domains. Repair Azure AD trust by using Azure AD Connect If you configured your AD FS farm and Azure AD trust by using Azure AD Connect, you can use Azure AD Connect to detect if you need to take any action for your token signing certificates. If you need to renew the certificates, you can use Azure AD Connect to do so. For more information, see Repairing the trust. Digital signatures and certificates - Office Support. More and more people and organizations are using digital documents instead of paper documents to conduct day- to- day transactions. By reducing dependency on paper documents, we are protecting the environment and saving the planet’s resources. Digital signatures support this change by providing assurances about the validity and authenticity of a digital document. For more information, see Add or remove a digital signature in Office files. What do you want to do? What is a digital signature? Signing certificate and certificate authority. Digital signature assurances. What is a digital signature? A digital signature is an electronic, encrypted, stamp of authentication on digital information such as email messages, macros, or electronic documents. A signature confirms that the information originated from the signer and has not been altered. The following is an example of a signature line. Top of Page. Signing certificate and certificate authority. Signing certificate To create a digital signature, you need a signing certificate, which proves identity. When you send a digitally- signed macro or document, you also send your certificate and public key. Certificates are issued by a certification authority, and like a driver’s license, can be revoked. A certificate is usually valid for a year, after which, the signer must renew, or get a new, signing certificate to establish identity. Note: You can learn more about public and private keys in this article. Certificate authority (CA) A certificate authority is an entity similar to a notary public. It issues digital certificates, signs certificates to verify their validity and tracks which certificates have been revoked or have expired. Top of Page. Digital signature assurances. The following terms and definitions show what assurances are provided by digital signatures. Authenticity The signer is confirmed as the signer. Integrity The content has not been changed or tampered with since it was digitally signed. Non- repudiation Proves to all parties the origin of the signed content. Repudiation refers to the act of a signer denying any association with the signed content. Notarization Signatures in Microsoft Word, Microsoft Excel, or Microsoft Power. Point files, which are time stamped by a secure time- stamp server, under certain circumstances, have the validity of a notarization. To make these assurances, the content creator must digitally sign the content by using a signature that satisfies the following criteria: The digital signature is valid. The certificate associated with the digital signature is current (not expired). The signing person or organization, known as the publisher, is trusted. Important: Signed documents, which have a valid time stamp, are considered to have valid signatures, regardless of the age of the signing certificate. The certificate associated with the digital signature is issued to the signing publisher by a reputable certificate authority (CA).
