Have you also got many sites in your tenant? Write-Progress is the bare minimum in a script that goes through all sites. But there is also another nice way to make easier to see the progress - estimated completion time.
Although the idea comes from another blog post (My life is a message), I thought it could be worth sharing it again, especially in the cloud context.
Here is a bit simplified scenario: Getting information for every site. The status message in Write-Progress contains also the estimated completion time.
I included the comments, and it should be straight forward to follow the logic in the script. Every iteration tries to estimate time, by calculating the average time of time per site, mulplying it by the remainder of the sites and adding it to the current time. The more sites are processed, the more accurate is the estimation.
