[SOGo] Missing own availability in invitation form

[breit...@picoquant.com]

Hello,

We are running a Mailcow/Sogo server (v. 5.12.3). When I setup an new 
event in my calendar in the web client and invite some other internal 
users I can see their availability but not my own. If I do the same in 
Thunderbird it works.

This happens with different users and browsers/operating systems on 
client side. Has anybody seen this before? What do we have to do to 
correct it?

Thanks

Jürgen
