Is there a limit to the number of shared mailboxes? [Microsoft 365]

Shared mailboxes are a fantastic way to set up a shared email-based communication network. Multiple users you need to communicate with can use a shared mailbox. This will allow you to communicate with every one of those members without any issues. However, are there any limits on how many shared mailboxes you can have? What will happen if you go beyond this limit. Have a read through our content and see if there is a limit on how many shared mailboxes you can create.

There isn’t a limited number of how many mailboxes you can have. Microsoft has not given any information on how many shared mailboxes you can create. This implies that you can create as many shared mailbox accounts as possible. Your limitation imposed here is your storage capacity for your Microsoft 365 account. For example, if you have a storage capacity of 50GB and then that’s the limit of how many mailboxes you will be able to create. If you do not have any storage left to create the shared mailbox, you will not be able to proceed with creating one. 

It is good to check and have enough storage to create shared mailboxes. Read through our guide and see what steps you need to take to check how much storage you have left for email-based activities. We have up to 50GB to use for email-based activities on our plan. You may have a different total cap, so check this information.

  • Firstly, open Office 365 from your browser. 
  • Now click on the launcher, which is illustrated by nine dots. 
  • From the launcher, click on the option for “Admin.” 
  • Now select the option for “Reports.” 
  • Now click on “Usage.” 
  • Find the option for “Email activity.” 
  • Now click on “View more.” 
  • Click on “Mailbox usage.” 
  • On the storage graph, hover over the current month. 

Once the process above has been done, you will have successfully checked how much storage you have left for email-based activities in Office 365. The process shown above will give you a breakdown of how much storage has been used up to this point for email-based activities. Microsoft has gone even further and split the different email-based activities to better understand how much storage is used and where. Simply navigate the mailbox option if you need to check how much storage you have left for mailboxes. This graph will keep updating as you create and delete mailboxes regularly. So it is a great idea to keep an eye on how much storage you have used and compare it to how much storage you have left.

Further limitations imposed on the creation of shared mailboxes

Users of Office 365 shared mailboxes are limited to 50 GB of storage capacity, but no license is required. To increase storage capacity, the Administrator must assign an Exchange Online Plan license, which provides users with more storage space and the option of archives and litigation hold. Furthermore, the account’s data will be deleted if the mailbox capacity is exceeded.

In some cases, the Administrator will change the ex-email employee’s to a shared mailbox, allowing other employees to access his or her data without difficulty. When the Admin tries to do the same, however, there is a potential that a configuration issue will develop.
