Get a report about people using other version of outlook when connecting to exchange 365

Frequent Contributor

Hi all,

We want to know how many people are trying to access Exchange 365 from other version of outlook, excluding Microsoft 365 version.

I tried checking Microsoft reports but they don't give that information on a per user basis. I found the RPC report but that is not enough. Is there a way to create a report , alert or a daily summary about users using other versions of outlook?

Hope the question is understandable.

If you want information about specific Outlook versions, your best best is to use the mailbox audit logs/Unified audit log.
Thanks Vasil, Here is what I ended up doing with PS based on your suggestion:
Search-UnifiedAuditLog -StartDate (get-date).AddDays(-8) -EndDate (get-date) -Operations Create -RecordType ExchangeItem -FreeText "OUTLOOK.EXE" -ResultSize 5000 | foreach {$_.AuditData | ConvertFrom-Json} | ? ClientVersion -notlike "16.0.13*" | select UserId,ClientIP,ClientVersion
