The information you are requesting is based on a lot of factors.<br />
<br />
First, What is that script doing,<br />
How that script is put together and how it calls the applications it uses.<br />
<br />
A good example of this is a script that is querying all the objects and properties for those objects in AD is going to run significantly more memory that a script that queries all the properties for a specific object.<br />
<br />
If you can provide a little more information we can help you, but this is a very open ended question with too board a scope to answer.

One limit to keep in mind is that you can run at most 3 remote sessions open for a single account. Which means that if you forget to remove session (Remove-PSSession) after you are done, you can easily block your access to Office 365 via PowerShell (at least until any active session expires).
