I have also seen this but have no explanation, it works for one user but not for another.
Do you see any further errors in mailbox.log when the guest user accepts the share?
When the guest user klicks the link i get the following in mailbox.log:
ERROR ..... share - Unable to handle request
com.zimbra.common.service.ServiceException: invalid request: no shares discovered
followed by many many many java-messages.
But in the meantime i found another error.
When creating a folder i get the error:
(Timer-Zimbra) share - Error during ACL push for mailbox 1 (-> or mailbox 2, mailbox 3)
com.zimbra.cs.ldap.LdapException$LdapEntryNotFoundException: entry not found - unable to create entry: no such object
Caused by: LDAPException(resultCode=32 (no such object), errorMessage='no such object', matchedDN='cn=files,cn=tenants,cn=hzndata')
In the web client the folder seems to be created normally and i even can upload files to it.
Hello Did you install 1.8.1 server directly or was your server at a lower version upgraded to 1.8.1? If it's an upgrade, can you tell us what you were running before?
it was a fresh install of v1.5, then updatet to 1.8, followed by installing the heartbleed-patch and closed with updating to 1.8.1.
Unfortunately i don't know at which step the error occured. Mentionable that there where problems updating the vApp. Had to restart the update two or three times.
Just for testing I've installed a second vApp now with version 1.8.1 fresh install and there everything works fine.
It looks like the multiple trials of update caused some problems. Are you okay with using the new install or do you still need to use updated instance?
For this time its OK to use / to do a completely fresh reinstall. But in a few days we start the productive environment and then the updates have to work! I also don't really know, what was the problem with updating.
For the updates:
will there be the possibility to download the update files and then do the update from a local ressource?
