Thank you for posting your query on Microsoft Q&A, from above description I could conclude that you are looking to upload certificate chain via single .P7b file in Azure Key Vault.
Please do correct me if this is not the by responding in the comments section:
Else follow the below actions:
- You need to Create and merge a certificate signing request in Key Vault.
- Add certificates in Key Vault
For partnered CAs (Digicert etc)
For non-partnered CAs(On-Prem)
- On the Certificate Operation tab, select Download CSR.
- Have the CA sign the CSR (.csr).
- After the request is signed, select Merge Signed Request on the Certificate Operation tab to add the signed certificate to Key Vault. it will merge the entire chain, provided the user has brought back a .p7b file to merge.
Thanks,
