Sehr geehrter Herr Robert
(s)eit zwei Wochen.....
Mit freundlichen Gruessen
Should I capitalize the (s) or not? In many video I saw it wasn't capitalize, so it that the general rule?

Sign up to join this communityIt depends on the punctuation you use at the end of the greeting line, "Sehr geehrter Herr Robert".
As it stands, you don't have any, which is wrong anyway. You can either end it with an exclamation mark (old style), in which case you have to start the first word of the text "Seit" with a capital "S". Or you end it with a comma (current style), in which case the first word of the text is not capitalized.
So either you write:
Sehr geehrter Herr Robert!
Seit zwei Wochen ...
Or:
Sehr geehrter Herr Robert,
seit zwei Wochen ...
It depends - on the punctuation.
If the address of the person is - as usual and recommended - separated by a comma, then the sentence just continues and 'seit' is not the first word of a new sentence:
Sehr geehrter Herr Robert,
seit zwei Wochen..
One can use an exclamation mark at the end of the address to the person. That's meanwhile uncommon and considered deprecated. In that case 'Seit' starts a new sentence and hence is capitalized:
Sehr geehrter Herr Robert!
Seit zwei Wochen...
Still just one person’s opinion there
- considering that almost everything written on StackExchange is more or less the opinion of the respective author, and very few SE's formally require citations or justifications of any kind, that seems not particularly important... the voting mechanism will take care of that.
In German, that letter is not capitalized.
The first word of the first sentence of the letter is "Sehr", which is capitalized, while "seit" is in the middle of that sentence.
