Exchange online archive file management help
Hi, I hope someone can lend me a hand. I run a computer service company in a very rural area. Most of my customers are home users with the exception for a few businesses I take care of in my area. One of my customers had to upgrade to a new program that had to integrated with Office 365 and using Outlook. This happened in 2017. No problems till now. The archive file on the exchange server is at its limit of 50G and starting to cause mail issues mostly warnings. I have never had reason to learn Exchange since none of my other customers use it and we have not had any problems till now. I am the Exchange Admin and have access to the Admin Center on line. I have had training in a few different programming languages, but trying to follow Microsoft's documentation for access and commands to manage then backup the archive files, lastly to remove it opening the storage space back up. I have a support request but what he sends does not work nor screen shots match. SO my question is can someone help me with needed commands or direct me to a complete example of commands to log into the server and then execute the commands to backup these 10 users accounts and then clean them up. If I knew about this file I might have been able to locate a class to learn Exchange server about this maintenance, but seeing it is a problem right now I have to deal with it now and not in 3 to 6 months. Any help is very appreciated.
