Cannot add a S3 Bucket

[vuducanha2]

Hi guys,

I am trying to add an Amazon s3 bucket, I followed the instructions on the wiki page but in the Admin page (Configure/ Global Settings/ S3 Buckets) the add button is disappear, I tried adding it in Zimbra Suit Plus/HSM but it was all saying "S3 Bucket is not valid.".

I am using Zimbra suit plus with trial license.

Sorry for my English skills.

Thanks for reading.
