Shielding Your Office 365 by Keeping Abreast of Mailbox Permissions Changes

What do you need to improve email security? Full control over access to mailboxes is probably at the top of your list. You need to keep an eye on every change to Office 365 mailbox permissions, because any unwarranted privilege escalation could threaten your data. Specifically, to ensure that no Office 365 users obtain inappropriate email permissions, you need a way to efficiently monitor who changes what mailbox permissions and when and where it happens, so you can quickly remediate suspicious alterations in order to protect sensitive mailbox content and prevent data leakage.

Tracking Office 365 shared mailbox permissions and mailbox permissions with native tools

When someone adds, removes or modifies mailbox or shared mailbox permissions in Office 365, you need to be the first one to know about it, so you can immediately detect and block external attacks or malicious user behavior. You can monitor Office 365 mailbox permissions using built-in tools. However, be ready to spend significant time in the audit search, playing with filters and digging around until you find the information you need, always dreading that a suspicious change will go unnoticed. Since there are no predefined reports on mailbox permissions in Office 365, every time you need to see who changed what permissions, you’ll have to generate a search, manually export the audit data into Excel format and then work at making it at least a bit easier to read.  Do you really have time for that? Isn’t there a more efficient way to identify suspicious activity that could threaten your email content?
