Microsoft 365 Online Email Archiving

What is Microsoft 365 online email archiving?

• Online Archive is for customers who have uncommonly large mailboxes. A user’s Online Archive acts somewhat like a second account in Outlook with its own folder structure. As a result, it isn’t included in searches performed from the Inbox.
• Once Online Archive is enabled, any message that is over 2 years old will be automatically be moved to the online archive.
• This policy can be changed once the archive has been enabled.
• Please note: once an online archive has been created, the user will need to run a search in the archive to find any messages that have been moved into the archive. The overall Outlook search will not automatically search the archive for messages.
