[Dr. Stephan Frisch]

Guten Tag, 
Hi, 

Ich bin vom 23.03.2023 bis 02.04.2023 nicht im Büro und kann die Emails nur sehr unregelmäßig lesen und beantworten. Die Emails werden auch nicht weitergeleitet.  

I am out of the office from 03/23/2023 to 04/022023 and can only read and answer emails very sporadically. The emails are also not being forwarded.  

Viele Grüße / Best regards
Stephan Frisch
