Hiii, i am new to this site so hello to everybody and thanks for the good job done.
I am confused if i can use the following sentence.
I would kindly ask your availability to arrange a meeting between You, our Team Leader and Myself.
I am not sure if Myself in the end of the sentence is Okay.
Many thanks in advance for your efforts.
The simply answer is that "myself" is not correct in this context wherever you put it in the sentence. The meeting will consist of "you, our team leader and me".
I would say "I am trying to organise a meeting for/between you, our team leader and me. Please let me know your availability next week".
Please see my other amendments to your post above in red.
There is no problem with "myself" at the end of a sentence when it's the correct word. "My boss was going to do it but he delayed for so long that I ended up doing it myself".
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
