I don't use Owncloud.

I've never seen anything about xx users left ..

Really? When you had say 8 or 9 did it still show you have XX users left?
None of mine use outlook connector


Wait now I see its only saying Owncloud for home Remaining licenses:2

I've got 21 on the CE. There's no limit, it's just that the CE is aimed at around 10. If you want 25, just define them - just be aware that if you want to use zarafa for mail, only 3 (in the CE) can use the Outlook connector, the rest have to use IMAP/POP/SMTP.

Im running the Comm version. Is there any way around the limit of 10 users.
Im not running a buisness or big office. Just a family website for genealogy, mail etc.
I dont need all of the features of the pro version.
I just need to up my email users/users to about 25 from the limit of 10.
More kids in the family are coming of age and want to use the email domain but Im at my limit and have even had to tell some sorry I cant.
Any way

I don't use any alternative. I use straight-through connections.

Please what do you use alternative to proxy ?
thanks

I don't use the proxy so have not remembered the answer. You may find it by searching the forum. Try this, for example.

Dear Mr.Nick Howitt
Good evening sir,

We have disabled the cash totally and browsing get much faster
What is your advise regarding "proxy is not well tuned for a large number of users"
Thank in advanced

There is no hard limit. I believe the proxy is not well tuned for a large number of users but it won't stop working.
