I have set the Message History setting to delete messages after 30 days. Since doing this, Messages app is quite buggy.

Question

I have no need to keep huge, old Messages conversations, so I recently set the Message History to delete messages after 30 days. Since doing this, however, I have noticed that the Messages app has become fairly buggy. Sometimes I'll open the app and it will look like there's no conversations, and the app prompts me to send a new message. Sometimes, I'll open the app to reply to an incoming message and my response will hang at 90% sent and then when I go back to the conversation list, it displays my outgoing, as-yet-unsent response as a new message, complete with little blue new message marker. The only way I have found to temporarily resolve these issues is to restart the phone. What's going on here?

Hi,
According to your description, I understand that you need to apply a rule to delete messages older than 30 days for all mailboxes in your environment. Is it right? If I misunderstand, please point it out.
As all above suggestions, we can use retention tags and retention policies in Exchange 2013 to achieve it. To apply it, we can try the following steps:
1. Login to Exchange Admin Center(EAC) in Exchange 2013 as an administrator.
2. Click compliance management > retention tags.
3. Click New Tag > applied automatically to entire mailbox(default).
4. Edit the Name, Retention action and Retention period(30 days), then
Save it.
5. Click Retention Policies tab > New.
6. Edit Name and add the Retention tags you created a moment ago. And
Save it.
7. Navigate to Recipients > Mailboxes.
8. In the list view, use the Shift or Ctrl keys to select multiple mailboxes.
9. In the details pane, click More options.
10. Under Retention Policy, click Update.
11. In Bulk Assign Retention Policy, select the retention policy you created to apply to the mailboxes, and then click
Save.
Hope it helps.
Thanks,
