Please feel free to

[suniljain]

Please feel free to schedule at your convenience.
Please feel free to schedule as per your convenience.

Are these sentences OK and do they convey the same meaning?

 

[Tarheel]

No, when you schedule you have to schedule something. Perhaps:

Please feel free to schedule an appointment at your convenience.

 

[suniljain]

Please feel free to schedule an appointment at your convenience.

Can I write as below:

Please feel free to schedule an appointment as per your convenience.

 

[Tarheel]

You can write what you want, but I'm not sure what "as per your convenience" means.

 

[Rover_KE]

It is hardly ever necessary to write 'as per'.

It's a throwback to antiquated business jargon. Let it die a natural death by the use of plain English.
