I am planning to deploy Deploy Office Online Server with SharePoint 2019. I found this below link and have to provide timelines to my client. is there any standard timelines by Microsoft where this work can be finished. for example, 1 month, 6 months etc.
I am looking forward for any blog by Microsoft for the standard timelines to complete this activity. I have given an estimate of 2.5 months which is not acceptable to client. Please advise.
